The Team Behind the Tools
Full-stack AI engineers who own every phase of the project lifecycle — from idea to production-ready systems, faster and more secure than traditional development.
Most of our time goes into our own self-service products — ChatKit and ToolKit — and we take on select custom development projects alongside them.
Why Our Approach Changes Everything
We combine years of full-stack experience with modern AI engineering practices — building faster, more securely, and with a level of ownership that traditional team structures simply cannot match.
Weeks, Not Months
What takes a traditional team months of back-and-forth, handoffs, and reviews, our engineers complete in weeks, smaller projects in days. Not by cutting corners — but by eliminating every inefficiency that slows conventional development down.
One Engineer. Full Lifecycle.
Most projects at M.D.N Tech are owned end-to-end by a single full-stack AI engineer — acting as architect, developer, and project lead at the same time. No translation loss between teams. No handoffs. One person with complete context, driving the project from discovery to production.
Production-Ready from Day One
We don't ship prototypes dressed as products. Features are tested, endpoints are secured, and deployments are validated before they go live. The result is software that works at scale — from day one.
Every Layer. One Team.
Front end, back end, mobile, infrastructure, design implementation, SEO — one team, no silos. Our engineers are built to own the whole product, which means faster decisions, cleaner architecture, and a final product that holds together under real-world conditions.
What We Build
We build across the full stack of modern product development. Whether you need an AI-powered platform, a Web3 system, a mobile app, or a production-ready web product — we have the depth to deliver it end to end.
Full-Stack Development
Scalable web platforms, APIs, and microservices built on a modern, proven stack: React, Next.js, TypeScript, Supabase, Railway, and Vercel. We write clean, maintainable code that performs under real traffic and scales without expensive rewrites.
Mobile Development
Native-quality iOS and Android apps built with React Native and Flutter. Full AI feature integration, mobile-optimized performance, Telegram Mini Apps, and Web3 wallet support. Enterprise-grade mobile, delivered by engineers who understand the full product.
Game Development
Unity and Unreal Engine 5 — from game mechanics and economy design to Web3 integrations and multiplayer systems. Built by developers who understand both the technical depth and the player experience.
UI/UX & Product Design
UX research, design systems, and pixel-perfect implementation from Figma designs. We handle the full design-to-code pipeline — including mobile optimization and SEO/GEO best practices — so nothing is lost between design intent and live product.
Blockchain & Web3
Smart contracts, DeFi systems, TGE launches, liquidity creation, and wallet integrations — built by engineers with hands-on experience across the full Web3 stack. Secure by design. Deployed with precision.
AI & Intelligent Systems
From intelligent automation to AI-native product features, we build systems that think, adapt, and operate without constant human input. Production-grade AI engineering — designed to solve real business problems at scale.
How We Build
Five phases. Full documentation. No phase begins until the previous one is approved — by our engineers and by you. We built this process to eliminate surprises, protect timelines, and ensure the final product matches what was agreed from day one.
1Discovery & Specification
- •Deep discovery session analyzing requirements and competitive landscape
- •Comprehensive specification document (SPEC.md) as single source of truth
- •Requirements, acceptance criteria, data models, API contracts documented
- •Explicit non-goals defined to eliminate scope creep
2Architecture & System Design
- •Complete system architecture: tech stack, database schema, API structure
- •Security model and AI integration points designed upfront
- •Every decision documented with rationale
- •Architecture validated against performance and scalability requirements
3Development & Execution
- •A dedicated engineer is assigned to lead the full build — responsible for every layer of the system
- •Our core team remains available throughout — ready to step in, review, or support where needed
- •Modern engineering tooling handles repetitive tasks; the engineer owns every decision and every line
- •Production-ready code with tests and documentation from the first commit
4Testing & Security Validation
- •Automated unit, integration, and end-to-end testing
- •AI-powered code review scanning for vulnerabilities
- •Test coverage and performance benchmarks
- •No code reaches production without passing quality gates
5Deployment & Continuous Improvement
- •Zero-downtime pipelines with automated rollback capability
- •Full observability: error tracking, performance monitoring, analytics
- •Proactive performance optimization post-launch
- •Ongoing support with rapid feature iteration

Enterprise Track Record
A Growing Team of AI Engineers
M.D.N Tech is a distributed team — five full-stack AI engineers today, working across time zones for B2B clients worldwide. We built our careers shipping enterprise systems, Web3 ecosystems and production apps, then rebuilt the way we work around Claude Code — the same expertise we publish as free skills in ToolKit.
Every project is owned end to end by one engineer with full context. And as new contracts land, the team grows — senior engineers, designers and marketers who work the same way.
Martin Jeřábek
Founder & CEO
Martin is the first point of contact for every project at M.D.N Tech — responsible for client relationships, project lifecycle oversight, and delivery confirmation. With 10 years in the blockchain and Web3 space, he brings strategic depth to every engagement: from scoping the right technical approach to ensuring the final product lands exactly as agreed.
