Speak, and the other side hears their own language — out loud.
From a Telegram bot to a full operating system - AI, web, mobile, blockchain, backend. If it's software, we build it.
Free 30-minute intro call. No obligation, no sales pressure.






Don't take our word for it. Believe them.
We don't just build for clients - we ship our own products too. These are live, in the market, and built end to end by the same studio.
Not videos, not screenshots. These are our own products, running here in your browser. Talk to one, ask it, make it do the maths — every answer is real.
Business owners, CEOs, entrepreneurs and CTOs, from all kinds of industries.
One bar. One quality. Every project.
Not promises, but a track record: co-authored research, open-source code, lessons from projects in production, and products you can try right now. Proof that what I build actually ships and holds up.
Co-authored research on the "Agentic Paradox" — how autonomous agents inherit outdated trust assumptions once they read private data, run shell commands and keep memory — and what hardens them against prompt injection. With Joran van Beek of Noaber AI.
A hands-on reverse-engineering teardown: what it actually takes to break into locked-down hardware, and why the difference came down to the device, not the skill.
How applied AI turns a vague hunch about student answers into a concrete, actionable signal teachers can trust. The thinking behind ClarixAI.
Not 'worked on.' Shipped. A look at what real delivery velocity looks like across three live products in a single week.
When the vendor app fell short, I built my own. A field note on owning your stack end to end instead of renting someone else's limits.
Field-tested lessons from critical-infrastructure work that most software teams never get to see. Where reliability is not optional.
Open-source decentralized app on Solana: minting, ownership and event flow on-chain. Shipped code, not slideware.
A working blockchain built from first principles: blocks, hashing and proof-of-work mining. The fundamentals, implemented, not just explained.
Security research reproducing a real remote-code-execution vulnerability. The offensive-security depth behind the defensive work I do for clients.
Not concepts — live products with real users. Open any of them and see the kind of software we ship.
