$ about
I'm a software engineer based in Belgrade, Serbia, with over 15 years in the industry. I graduated from the top computer science faculty in the country and have been building things for US and EU markets ever since.
Most of my career has been spent in the Ruby on Rails ecosystem—it's where I do my best work. I've built payment systems, trading platforms, reporting tools, and helped startups go from zero to funded.
I've also been on the other side. I co-founded two startups, raised investment, went through an accelerator in Prague, and learned what it actually takes to build a product people want.
These days I practice AI-first development. Claude Code is my pair programmer, MCP servers handle the workflows, and I build custom AI skills for repetitive tasks. The result? Faster delivery, fewer bugs, better code. This is how I work now.

$ cat journey.txt
Started with enterprise Java systems for healthcare, processing payroll for thousands. Then .NET, Android, and eventually Rails—where I've spent the last decade.
Now I work AI-first. Claude Code writes code with me, MCP servers automate the boring parts, custom AI skills handle what used to take hours. This is not about replacing developers. It's about 10x-ing what one developer can do.
Faster. Cleaner. More reliable. That's why I build this way.
