Andrei Csatlos
I ship production-grade products at startup speed.
I'm a hands-on startup CTO: I rebuild messy systems, help businesses embed AI into their engineering workflows, and train engineers to move faster with it. I build AI layers around real codebases that preserve context, grow a shared knowledge base, and turn the product into a second brain your team can keep learning from.
From SaaS to DeFi, I work where the stakes are real: messy data, operational load, customer workflows, and teams that need momentum without fragility.
What actually works
I share what actually works in AI, product, and engineering, and how to make it work in your team too. The parts people usually keep to themselves.
Selected work
Real systems, real constraints, measurable outcomes.
Open any card for the full case study: problem, system design, and measurable impact.
Atlas Analytics
Took over a brittle B2B SaaS product and rebuilt the core platform in 2 months so the team could ship without fighting the system.

LendeXe Finance
Co‑founded and shipped audited DeFi primitives (stablecoin + cross‑chain lending), treating security as a product requirement. Optimised protocol choices and infrastructure to cut costs and improve speed while maintaining robust contract design.

SmartBear (via Waverley)
Shipped and maintained enterprise-grade features and fixes for ReadyAPI in distributed teams, balancing reliability, velocity, and real customer impact. This is where “production‑grade” became non‑negotiable—because users notice every edge case.

Ideafy
Built and launched an MVP in under a month, then tested it in the real world with companies - not just in demos.

Say hello
If you're building something ambitious (AI automation, data-heavy SaaS, or a product that needs shipping fast), I'm happy to compare notes.
