Hi, I'm
Senior Software Engineerfull-stack TypeScript · AI-first
I build web products end to end with AI agents in the loop - Node.js and TypeScript on the backend, React on the frontend, and the AWS infrastructure underneath. 14 years in, based in Prague.
01 · About
I'm a full-stack engineer who cares about code that is easy to read, easy to change and boring to run in production. I've led teams through big migrations (PHP to Node.js & React, on-premise to AWS), shipped SDKs used by over a million TV viewers, and today I work on one of the best-rated CRMs at Pipedrive.
AI is how I work now, at Pipedrive and on my own projects below. opinio.live is built and run by me and AI agents - they do the work, I stay in control - from the database to the Android app, including AI-written news, translations and content scoring in production.

Senior Software Engineer
- Present
Pipedrive is one of the best user-rated CRM tools, with a focus on small and mid-size companies. As they use the tribes & missions framework, I joined Prague's tribe (instead of a team).
As a full-stack JavaScript software developer, I work with Node.js and TypeScript on the backend and with React on the frontend. I am also part of the on-call team, which takes care of microservices running in production.
Since 2025 I've worked AI-first and I'm one of the heaviest AI users in my tribe. AI agents write, test and review most of my code - I steer them and stay in control of what ships.
GraphQL Software Developer
-
Nangu.tv's IPTV/OTT solution has more than 1 million users in Central Europe - it is used by major operators like O2 and Orange.
As part of the GraphQL team, I worked with Node.js and Apollo, and I was responsible for developing and maintaining a unified JavaScript SDK written in React/React Native for our clients' frontends.
Head of Development · Software Developer Lead

My first job in Prague was at Economia, one of the biggest Czech media houses, with brands like aktualne.cz, DVTV, Hospodářské noviny, and RESPEKT.
We decided to replace PHP with Node.js & React, move from on-premise to the cloud (AWS), and adopt DevOps. As a team leader, I drove those changes while coding and mentoring others. It took almost a year to accomplish at centrum.cz, and I gave a talk about it at ReactiveConf 2019.
Finally, after a few years, I moved into the Head of Development role to help roll out these changes company-wide.
Software Developer

AtNat was an ambitious startup. Back then, it was challenging to create an isomorphic JavaScript web application. It was my first encounter with Node.js and Angular.
Software Developer

Digital Solutions is a smaller IT company specializing in information systems (B2C), with clients like MMReality (the biggest real estate agency in the Czech Republic).
I spent most of my time working on MMReality's internal system, written in PHP and JavaScript, with a strong focus on code quality. It was my first real experience with advanced programming techniques like OOP, Clean Code, Agile, etc., and with document-based databases.
Junior Software Developer

My very first professional experience began at eBrana immediately after graduating from the University of Pardubice. I started with PHP and vanilla JavaScript, creating and updating features on clients' e-shops to fit their needs.
