The companies I've worked at.
Experience
Pipedrive
Senior Software Engineer
May 2021 - 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.

Other technologies I would like to mention related to my job at Pipedrive are Kubernetes and AI tools like Claude.

Nangu.TV
GraphQL Software Developer
Feb 2020 - May 2021

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.

Economia
Head of Development
Software Developer Lead
Oct 2015 - Feb 2020

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.

AtNat
Software Developer
Mar 2015 - Sep 2015

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.

I left after several months because I realized that startup culture does not suit me.

Digital Solutions
Software Developer
Apr 2013 - Mar 2015

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.

eBRANA
Junior Software Developer
Jul 2012 - Mar 2013

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.
