About
From incident response, I moved into cloud engineering and automation at TrustSoft, including work for Groupon. Now I bring that experience to product engineering at Glow.

How I got here
I came to engineering from economics, wanting to build real systems rather than model them. I started with Linux at Engeto in Prague, studied intensively on my own and moved into 24/7 production operations.
I stayed for the analytical challenge: something breaks in production, and you have to work out why.
The economics never went away. I still judge the work by the time it saves and what it costs to run.
Ronald Coase explained in Why Do Firms Exist? that companies exist to reduce coordination and transaction costs. That is why business automation and shared human-agent workflows make sense: what we build at Glow is about lowering the cost of coordinating work across people, AI agents and tools.
Career
- 2018–20
CDN77
Support
Two years co-leading a 24/7 operations team. Angry customers, 3am pages, real outages. It taught me what happens downstream of a bad decision.
- 2020–21
Leveris
Operations
At a banking software company, I kept internal systems running and automated repetitive work. I also led the ISO 27001 compliance program and wrote the team’s operating procedures.
- 2021–25
Engineering
At TrustSoft, I built a governance framework above Amazon's AWS Control Tower. It became the company's standard for almost all projects and the backbone of Cloud Foundation, used across 15+ enterprise estates.
- 2024–25
Engineering
A year and a half embedded on one long-running project through TrustSoft, automating how their teams got new cloud projects created.
- Dec 2024–Current role
Founding Product Engineer
I joined Glow as its fourth team member. I pushed for multiplayer so people and AI agents could build on a shared live canvas, with the automation taking shape in front of the user. I help define and test product behavior, work directly with clients and build automations.
I worked at Glow and TrustSoft in parallel after joining Glow in December 2024.

What I learn from
Courses, books and channels I keep coming back to, and what I use them for.
Where it started (2)
Engeto: the Linux course
coding school · PragueA classroom in Prague, evenings, before anyone would hire me. This is where IT caught me and did not let go.
Nick Saraev
business automation · YouTubeThe first automation channel I studied. Beyond practical, unedited builds, it helped me understand the business side of automation and how to judge what is worth automating for clients.
For the work (7)
Andrej Karpathy
AI & deep learning · YouTubeFirst-principles explanations of language models and how to build practical software with them.
Anthropic
AI architecture, courses & YouTubeEngineering talks on YouTube and courses on Anthropic Academy covering Claude, Model Context Protocol (MCP) and building reliable agent workflows.
DeepLearning.AI
courses · Andrew Ng and othersWhere the AI I put into automations stops being a black box. Short courses, done properly, on the parts I actually ship.
n8n · Make · Zapier · Gumloop
automation platformsTools I've used in practice and still study closely. Each one solved real problems well, and I like learning from what they do best.

Domain of Science
science · YouTubeI love this channel. Dominic Walliman's visual maps of physics, mathematics and computer science show how whole fields fit together.
Art of the Problem
history of computing & AI · YouTubeVisual histories of information theory, cryptography and neural networks, traced back to the original ideas.
Computerphile
computer science · YouTubeFor when I want to go full nerd on low-level computing, cryptography and strange corners of computer science.
Principles · Ray Dalio
systems & decision-making · YouTubeTreating life and work like a system: writing down clear principles, looking at mistakes without ego, and improving how decisions get made.
Music, unwinding & a little treat (5)
