Services & Expertise
Full-service development from web to mobile to hardware, backed by 25+ years of experience
Crafting lightning-fast, modern web applications with SvelteKit, TypeScript, and NodeJS. No bloated frameworks here—just clean, efficient code that actually works.
Building beautiful cross-platform apps with Flutter and Dart. Team up with my mate Eusebiu, and your app will be properly brilliant across iOS, Android, Win/Mac/Linux. I often do Capacitor hybrid apps, too.
Blazingly fast APIs with Hasura, GraphQL, and PostgreSQL. Wrote the book on it (literally—for Packt Publishing). Your backend will be sorted in no time (= cheap).
From smart locks to plant watering systems, I build IoT solutions that actually work. ESP32 specialist with hands-on soldering and product development experience.
Docker-based deployment solutions that won't keep you up at night. Reliable, scalable, and properly configured—because your app deserves a good home.
TDD, Agile, pair programming, code quality—all the good stuff. Happy to collaborate with your existing team or teach best practices. No jargon, just results.
I've built a solid boilerplate so your project is deployed and live within hours—signup, login, forgot password, email integration, file upload, and everything else almost every project needs. It includes comprehensive AI agentic instructions covering best practices and the full architecture. Once I've set it up manually, AI agents start planning, building, and testing your features while I orchestrate and correct. Over time the AI fully understands the project, and I'll train you to direct it for future changes—without things breaking.
AI that actually moves the needle.
We don't just talk AI — we build it, train your team to use it, and make sure it sticks. From Claude Code to agentic workflows, for non-technical individuals to enterprise teams. Stop paying to experiment. Start paying for results.

2h
free consultation to start
No coding background needed. I teach prompt engineering, Claude Code, and MCP server setup to non-technical individuals and teams. You'll go from zero to running AI agents in your own business — not just watching demos.
I design and build AI agents, n8n automations, and MCP-powered workflows that create real, measurable ROI. Before anything gets built, we find the 3–5 opportunities worth the investment — no science projects, no PowerPoint decks.
Shipping a demo isn't success. Adoption is. I work alongside your teams so AI systems are understood, trusted, and used every day. Claude Code, agentic AI, IoT smart solutions — tailored to your exact business.

A proper task management solution that bridges the gap between developers and clients
The Problem
Developers work in GitHub. Clients find it overwhelming. Trello costs a fortune for teams. Jira is overkill for most projects and far too complicated.
The Solution
A clean, intuitive Kanban board that syncs seamlessly with GitHub issues whilst providing a friendly interface that clients actually enjoy using. Best of both worlds.
How to use?
If you want to start using it yourself or with your team, there are three options: below are links to use it as a free cloud service, or you can download it from GitHub to set it up on your own server (instructions included). You can also contact me, and I'll set it up on your server for about £80 (server costs up to £3/month).
Voice & AI Integration
Dictate tasks and let AI correct and enhance your notes. Research mode for intelligent task creation.
True Multilingual
Not in your language? Use AI to translate initially, then refine it yourself. Proper international collaboration.
Everything You Need
Subtasks, file uploads, rich text, comments—all synced with GitHub. Your developers stay in their flow, clients get a lovely interface.

About Me
A fervent technology enthusiast dedicated to excellence
With over 25 years of software development under my belt, I've been turning ideas into reality since before "the cloud" was a thing (we just called it "someone else's computer" back then).
I'm a senior specialist in SvelteKit, TypeScript, and NodeJS. For mobile apps, I team up with my brilliant mate Eusebiu—together we craft exceptional Flutter applications that work beautifully across iOS and Android. We run Code New Ltd, a UK-registered company serving clients primarily across Britain.
When it comes to APIs, I'm properly quick with Hasura and GraphQL—so much so that I wrote a book about backend development for Packt Publishing. PostgreSQL, REST, PHP, Python, Rust—I've got you covered on the backend.
In the realm of IoT and hardware, I specialise in ESP32, C++, Arduino, and Raspberry Pi. From smart locks to automated plant watering, I build things that actually work in the real world—complete with hands-on soldering and product development.
Based in Estonia but with 7 years living in London and still visiting the UK 2-3 times yearly, I understand what British clients need. No faff, just quality code delivered on time.

Get started with Hasura in a short time and master your skills with more advanced custom business logic and SQL. Start developing complex and scalable real-world back-end APIs multiple times faster.
Wrote a comprehensive book on backend development for Packt Publishing, sharing expertise with the global developer community.
Leveraging the finest stack and techniques to deliver backend, API, and admin panel functionalities significantly faster than traditional approaches.
Passionate about research and innovative approaches to ensure rapid, secure, and bug-free delivery of software solutions.
Love getting hands-on with projects and pair programming with existing development teams to deliver the best results.
Why "e-Stonia"?
A bit of history behind the name and my connection to the UK
Back in 2004-2015, I ran a software development agency called e-Stonia. The name was a nod to Estonia's reputation as the world's most digitally advanced nation—the original e-country with e-governance, e-residency, and all that good stuff.
At the time, I was connecting British clients with talented Estonian developers. The hourly rates in Estonia were remarkably lower than what you'd pay in London (we're talking £££ versus what was essentially pocket change). Everyone was happy—clients got brilliant code without breaking the bank.
Fast forward a bit, and we evolved into CrewNew, a freelancer agency that grew to over 11 full-time programmers and hundreds of Eastern European freelancers (mostly from Romania and the Balkans). Quite the operation.
Since 2022, I've been back to my roots—working solo on most projects, occasionally teaming up with my brilliant mates for the bigger gigs.
"The rates aren't quite as bargain-basement as they were back in 2004, but you still get world-class development without the London price tag. Plus, I actually answer emails."

What services does e-Stonia offer?
e-Stonia offers full-stack web development (SvelteKit, TypeScript, NodeJS), cross-platform mobile apps (Flutter), fast APIs (Hasura, GraphQL, PostgreSQL), IoT and hardware development (ESP32), DevOps and deployment, plus AI training and automation — including Claude Code training, MCP server setup, and n8n workflow automation for teams and businesses.
Do you offer Claude Code and agentic AI training?
Yes. Kaspar teaches prompt engineering, Claude Code, and MCP server setup to both non-technical individuals and technical teams, then builds AI agents and n8n automations that deliver measurable ROI. Training takes you from zero to running AI agents in your own business, with support continuing from pilot through to full production adoption.
Can you build custom IoT and hardware solutions?
Yes. Kaspar is an ESP32 specialist with hands-on soldering and product-development experience. He builds smart locks, automated plant watering, smart booking and heating systems, connected vending machines, and other bespoke IoT devices using ESP32, C++, Arduino, and Raspberry Pi.
How much does it cost and how do we start?
The first 2 hours of work are free, and the initial consultation is a no-obligation 15–30 minute call. You get world-class development at Estonian rates rather than London prices — for example, self-hosting the open-source Kanban tool can be set up for around £80 plus roughly £3/month in server costs.
