I build things, break most of them, and write down what I learn.
I'm Ladi, Ladislav Martincik. You're probably here to decide something — hire, contract, build together — so this page skips adjectives and keeps receipts: a game shipped on Steam, a Chrome product with its revenue verified in public, agent infrastructure I use every day, and a post-mortem for every project, including the killed ones. Czechia, CET, on a deliberate sabbatical, building AI-first tools solo.

- ex-CTO · now solo
I've never been able to sit still on one stack. I caught Rails early, when the Czech ecosystem was three blog posts and a prayer. I caught React Native early and shipped OSS bridges, one still gets downloaded. I went four years deep on a Solana protocol. Now the whole studio points at agents. Four bets, each made before it was safe.
There are two tracks here, and they run on opposite rules. The commitments run long and finish: eight years as CTO at Foundum, five years to ship one game on Steam, four years at Access from founding week to sabbatical. The experiments run cheap and die young, each with a written post-mortem. That split is deliberate. Killing small things fast is what protects the years I give to the big ones.
So the wiring is non-linear, but the method never changes: spec it, loop it, verify it, write down what it taught. Domains rotate; the discipline doesn't. It's also why the arc keeps catching waves early: you see the next one by standing in several fields at once.
I think the UI is splitting in two (task screens get generated and thrown away; the trust layer is what's worth owning) and whoever keeps building UI-heavy apps is going to regret it. So I stopped waiting and started building the plumbing for the agent era: memory, sandboxes, reasoning, routing. I don't write code by hand anymore; I direct the loop in English and own the system that catches wrong.
To be clear, the bet is about task screens in apps, not about websites: a portfolio is a trust surface and deserves design. What this site dogfoods is the split itself: a crafted face for people, an agent-readable twin at /llms.txt for the screening agents.
One human note before the receipts below: the studio isn't called Backtomeaning by accident. The sabbatical is for remembering why I build at all, not just what ships next.
The arc
- 2026 →
Backtomeaning · solo
Backtomeaning is my one-person studio. Sabbatical by choice. Building AI-first tools (LoomBrain, sandcaster, my Claude Code plugins) and betting the next decade on agents.
- 2022–26
Access Protocol · Web3
Four years on a Solana content protocol, founding week to sabbatical: the web platform, design system and SDKs around the chain, then the AI-agents pivot from inside. Not a tourist.
- 2021–25
Amenti Studio · founder
Built and shipped Book of Aaru, a commercial narrative game, on Steam. Five-year arc, a team of five to eight, disbanded. The game still sells.
- 2017–21
Learnlife · Head of Tech
EdTech in Barcelona. Building learning systems for a different model of school.
- 2010–18
Foundum · CTO
Eight years leading engineering for a platform connecting startups with the people around them. Where I learned what a CTO actually does.
- 2010–11
Red Hat · senior engineer
Virtualization, for six months. Learned I need small and high-agency. Big was not for me.
- 2007–10
Ticketsolve · XING · Visrez
Agile the hard way (via the UK), engineering management in Barcelona, .NET-to-Rails migrations. Two stints at XING as Scrum Master and Agile coach: my first job was making teams ship better, not typing more. The formative years.
- 2005–07
skvely.cz · co-founder
A web agency started with a friend in our last years of university. My first company. I left after two years, and the founder itch stayed.
- 2005
Rails, early
An early Rails adopter in Czechia. The first bet: shipping beats waiting for the docs.
- 1997–2005
Informatics & Software Design
Engineering degree. The long apprenticeship before any of it made money.
Work with me
I'm open to senior engineering and engineering-leadership roles, and to contract work, especially with teams building for the agent era. What you get is on this site, receipts included: the projects, the failures with their lessons, and the one-page CV. Point your AI at /llms.txt if that's how you screen. Mine would.
