Tin Marković

Independent technical partner

Insurance, payments, accounting, and the systems that make businesses run — not just the code.

If you're looking for someone to implement a spec, I'm not your person. If you have a problem and need someone who can diagnose it, design a solution, lead a team to build it, and hand it over cleanly — we should talk.

Domain expertise

I've worked inside insurance infrastructure, payment processing systems, legal workflow automation, and data platforms. The kind of systems where a bug doesn't mean a bad UX — it means a regulatory breach, a missed settlement window, or a payroll run that doesn't run.

I understand these domains because I've built and broken systems inside them. I use LLMs. I don't outsource the thinking to them.
