WHAT WE OFFER
OUR SERVICES
Interfaces that stand out and are easy to use. The site you’re looking at right now is the proof.
Pages with one clear goal: enquiry, booking, sale. Built for load time and clarity rather than on a site-builder template that a thousand others use as well.
Interfaces for data and processes – bookings, customers, figures. Everything in one place instead of spread across five Excel files and three portals.
Three-dimensional scenes right in the browser, with no plugin and no download. Rotate products, walk through rooms, hold attention.
Motion that explains something instead of just flashing. Content unfolds as you scroll and leads through the story rather than showing everything at once.
A kit made of your own building blocks – colours, typefaces, buttons, cards. New pages come together faster and look the same everywhere.
Load time is a ranking factor and a reason to bounce at the same time. We measure what Google measures and optimise against exactly that.
Usable with the keyboard, readable with a screen reader, enough contrast for poor eyesight and bright sunlight. Widens the audience and lowers legal risk.
Systems that run reliably and grow with your business.
APIs & data modelling
The structure behind the interface: what the data looks like, how it relates, how other systems fetch it. Built cleanly means extended later rather than rebuilt.
Authentication & role systems
Login, passwords, sessions – and who may see and change what. From a single admin to a team with graded permissions.
Databases & migrations
Where your data lives and how it can be changed without anything getting lost. Every structural change is traceable and reversible.
VPS setup & deployment
Your own server instead of a rented site builder: set up, secured, with automatic HTTPS. New versions go live with a command, not an FTP upload.
CI/CD pipelines
Code only goes live once it builds and passes the checks. Fewer manual steps, fewer broken deployments, no ‘it worked on my machine’.
Security & hardening
Firewall, Fail2Ban, encrypted connections, validated input. Closing attack surfaces before anyone goes looking for them.
Monitoring & backups
You hear about an outage before your customer rings. And if something does break, there is a clean state from yesterday.
Maintenance & further development
Updates, security patches, new features. A website is not a piece of furniture – it needs looking after, or it quietly goes out of date.
Dull manual work out – processes that run by themselves.
Internal tools & dashboards
Tools for your day-to-day, not for the customer. Quotes, appointments, stock – in one place instead of spread across notes, spreadsheets and chat threads.
Integrations & data import
Fetch data from other systems and load it in automatically. No more copy and paste between portal, spreadsheet and website.
Recurring processes & cron jobs
What should happen every day at seven happens every day at seven. Backups, exports, reminders, price updates – without anyone having to think of it.
Reporting & exports
Figures as PDF, CSV or email, automatically at the end of the month. Instead of gathering them by hand every time.
Connecting your tools
An enquiry comes in, lands in the customer list, the confirmation goes out and the appointment is in the calendar – without anyone clicking in between. Your tools work together instead of side by side.
Notifications & bots
Alerts where you actually read them: via Telegram, email or push. A bot reports new enquiries, orders or anything unusual the moment it happens.
Market watch & price alerts
Keep an automatic eye on offers and prices online and get a message as soon as something suitable turns up. Only from sources whose terms allow it.
AI where it adds real value – not as a buzzword.
AI-assisted features
Suggesting copy, sorting content, triaging enquiries. AI where it takes work off your hands – not as a sticker on the home page.
Chat & assistant interfaces
An assistant that knows your own content and answers questions about it. For customers on the website or internally for the team.
AI agents for workflows
An agent works through tasks in several steps on its own: researching, sorting, drafting. Where a person should decide, it stops and asks.
Voice assistants
An assistant you talk to instead of typing: it listens, understands the question and answers in its own voice.
Reading images & documents
The AI reads photos, receipts and PDFs and pulls out what matters – amounts, dates, names. Instead of typing them up by hand.
Bespoke web apps
When off-the-shelf software doesn’t fit: an application that maps exactly your workflow. No getting used to someone else’s logic, no paying for features you never use.
Progressive Web Apps
A website that behaves like an app – installable, offline-capable, with push notifications. No app store and no two separate builds.
Desktop software
Programs for Windows that run on your own computer without a browser – when a task should stay local or has to work without an internet connection.
Visibility that can be measured – technical SEO, clean data, campaigns with figures behind them.
Search engine optimisation (SEO)
Technical foundations and content prepared so that search engines understand them: structure, load time, markup, internal linking.
Local SEO & Google Business Profile
Being found by people near you. Listings, map services, reviews – for everyone whose customers are local.
Analytics & conversion tracking
See where visitors come from and where they drop off. Measured in line with data protection law, so that decisions rest on figures rather than gut feeling.
Google Ads & paid search
Paid ads for search terms where waiting isn’t worth it. Set up, monitored and fine-tuned so the budget doesn’t fizzle out.
Social media marketing
Content and campaigns on the channels your customers are actually on. With a goal and measurement, not as an end in itself.
Hardware that works. Repair, build and setup – for private individuals and small businesses.
PC & laptop repair
Fault-finding on hardware and system: won’t start, runs too hot, has got slow over the years. Find the cause first, then repair – no swapping parts on a hunch.
Upgrades & new builds
More memory, a faster SSD, a new graphics card – or a completely new machine straight away, put together around what you really need rather than around the brochure.
Operating system & software
Windows or Linux set up cleanly, plus drivers, updates and the programs you work with. The machine comes back fully set up, not as a building site.
Data transfer & backup
Files, emails and settings from the old machine to the new one. Plus a backup that runs by itself, so that a fault doesn’t cost you everything at once.
Network & Wi-Fi
Routers, repeaters, network sockets and shares – set up so that it works in every room and not every guest ends up on the company network.
System clean-up & protection
Removing malware, tidying up startup programs, setting updates and antivirus correctly. A machine that is fast again and stays that way.

// TOOLS OF THE TRADE
Tech stack
What it’s built with – no site builder, no theme.
FRONTEND
The skeleton of every website: the structure and meaning of the content. Clean HTML is the basis for search engines and screen readers understanding a page at all.
The presentation layer: colours, spacing, layout, motion. Modern techniques such as grid and container queries instead of the workarounds of ten years ago.
The language that brings websites to life in the browser. Interaction, logic and a response to everything the visitor does.
JavaScript with type checking. Errors show up while writing rather than in front of the customer, and the code still makes sense six months on.
The library behind most modern interfaces. Building blocks that are reused rather than pages that are copied.
The framework around React. Pages are pre-rendered, so they load faster and are readable for search engines.
A build tool for modern web interfaces. Changes show up in the browser at once during development, and the result is a lean bundle for delivery.
The technology that lets a website behave like an app: installable, with its own icon, usable without a connection. The service worker is the small program in the background that keeps the content ready for that.
STYLING & UI
Styling right on the element instead of in separate stylesheets. Quicker to build and without the legacy that nobody wants to touch later.
Ready-made components that are copied in rather than pulled in as a dependency. They live in your own project and can be changed freely, with no dependence on someone else’s design decisions.
The browser’s two-dimensional layout system. Complex grids that reflow cleanly on every screen, without workarounds.
Invisible primitives for menus, dialogs and switches – with correct keyboard handling and screen reader support out of the box.
Animation library for React. Transitions that feel fluid instead of hard jumps between two states.
A fixed set of colours, typefaces and building blocks. New pages look right automatically instead of being reinvented every time.
3D & MOTION
The standard library for 3D in the browser. Scene, light, camera and material – no plugin, right on the website.
Connects Three.js with React. 3D scenes are made from the same building blocks as the rest of the interface.
Small programs that run directly on the graphics card. They produce effects that would not be possible with images and CSS.
A tool for precise animation sequences. Especially for stories that unfold step by step as you scroll.
The interface through which the browser talks to the graphics card. The basis for everything that runs in 3D or with shaders.
Smooth scrolling with inertia. The difference between ‘works’ and ‘feels well made’.
The standard format for 3D models on the web. Tightly packed, so that even detailed objects load quickly.
Finishing the rendered 3D image: glow, blur, grain. The step that turns a clean scene into one with atmosphere.
BACKEND
JavaScript on the server. One language for interface and backend, and so less friction in the project.
A very lean server framework. Fast, light on resources and able to run on edge servers too.
Two ways for interface and server to talk to each other. REST as an open standard, tRPC when both sides come from one project and are meant to share types.
The tried and tested server framework for Node.js. Widely used, well documented, and there is a proven extension for almost any task.
A standing connection between browser and server. Messages and changes arrive at once, without reloading the page – the basis for chats and live displays.
A versatile programming language for automation, data processing and AI. Much of what should run by itself in the background can be built quickly and reliably with it.
A library for sign-in and sessions. Login, password reset and roles run inside your own project instead of at a third-party service.
DATA & SERVICES
The standard database for serious applications. Mature, reliable and able to take the load even with large volumes of data.
A database as a single file, with no server process of its own. Ideal for smaller projects and for backups that consist of copying a file.
Translates between database and code, with type checking. Queries are checked before they ever run.
A database that stores data as flexible documents instead of fixed tables. A good fit when entries are structured differently or their shape changes often.
A payment service for online shops and subscriptions. Cards, wallets and other payment methods run through one interface – the sensitive payment data stays with the provider.
A service for sending system emails: order confirmations, password links, notifications. Built so that such emails are delivered reliably.
SERVERS & HOSTING
Applications run in self-contained containers. What runs on the development machine runs identically on the server.
Web server with automatic HTTPS. Certificates are fetched and renewed on their own, without anyone having to think of it.
Classic web server and reverse proxy in front of the application. Proven, fast and configurable down to the detail.
Process manager for Node applications. Starts them again automatically after a crash or a server reboot.
A network in front of the site for DNS, delivery and attack mitigation. Content arrives closer to the visitor, attacks don’t get through in the first place.
The operating system most servers on the internet run on. Stable, frugal and configurable down to the last detail.
A computer the size of a credit card. Quiet, low on power and strong enough for a small server of your own or a controller that runs around the clock.
QUALITY & SECURITY
Version control: every change to the code is recorded, traceable and reversible. GitHub is where the code is kept safe and reviewed before it goes live.
Automated workflows on every code change: build, check, ship – no manual steps.
Automated tests in a real browser. A script clicks through the site like a visitor and reports when something stops working after a change.
Google’s measuring tools for load time, accessibility and search engine basics. They deliver figures instead of gut feeling, before and after every change.
End-to-end encryption right in the browser. Messages are encrypted on your own device and only become readable again at the recipient’s end – even the server in between cannot read them.
A modern VPN: an encrypted tunnel between two devices. It makes a server at home or in the office reachable on the go without exposing it to the open internet.
AI
Connection to the Claude models. For text processing, analysis and assistant features right inside the application.
Connection to the GPT models. A second source, so that a project doesn’t depend on a single provider.
The AI answers on the basis of your own documents instead of from general knowledge. Fewer made-up answers, more relevance to your own business.
Databases that search by meaning instead of by keyword. The basis for the AI finding the right passages at all.
Texts are translated into series of numbers that represent their meaning. That makes it possible to find content that is similar in substance automatically.
AI models that understand images. They recognise what a photo shows, read text in it and sort images by content.
AI AGENTS & VOICE
An AI assistant that works right inside the project: reading, changing and testing code. Routine work goes faster, the decisions are still made by a person.
A toolkit for building your own AI agents. It produces assistants that work through tasks in several steps and use tools along the way – with clear limits on what they may do.
Instructing models so that they reliably do the right thing. The difference between usable results and arbitrary ones.
Recurring parts of an AI request are cached instead of being processed anew each time. That makes answers faster and running costs lower.
Speech output with natural-sounding voices. Texts are read aloud, and an assistant gets a voice of its own.
Small programs that send messages and take commands via Telegram. Handy for alerts on your phone as soon as something important happens.
Nothing is impossible – that is the starting point for every project.
