Get to know me
Hi there! My name is Petar, and I'm passionate about building things on the web. I'm the kind of person who truly cares about the details, and that's exactly how I approach engineering. I don't build things just for the sake of building them — I build with purpose and with the bigger picture in mind, always asking myself how each piece fits into the whole.
I've spent 7+ years building production software across fintech, enterprise, and startup environments — from Fortune Global 500 platforms to early-stage products. Whether it's a design system, a complex data-heavy dashboard, or a full-stack application, I bring the same care and intentionality to every line.
Outside of engineering, I'm a singer in a band. I believe creativity in one domain sharpens your thinking in another.
My values
I care about the details. Not because someone is watching — because quality compounds, and I want what I build to still be good long after the sprint is over.
I don't build things just for the sake of building them. Every decision should solve a real problem and move the product — and the people using it — forward.
Before writing a line, I ask how it fits the whole. Good architecture outlives any single feature — so I always build with the bigger picture in mind.
Building on the web isn't just my job — it's something I genuinely love. That energy comes through in every project, and it's what keeps me raising the bar.
How I build software
Every feature matters, but the architecture behind it determines how well the product grows. I build with the bigger picture in mind, so today's decisions don't become tomorrow's technical debt.
Every technical decision should solve real problems and create value for both users and the business. The best engineering moves the product forward, not just the codebase.
The best solutions remove unnecessary complexity, making products easier to build, maintain, and evolve. Simplicity isn't cutting corners, it's making the right trade-offs.
AI helps me move faster, explore ideas, and automate repetitive work. Engineering judgment, product thinking, and experience are what turn that speed into great software.

My Services
From idea to production-ready software.
Whether you're validating a new idea, launching an MVP, or scaling an existing product, I will help you transform your vision into a scalable web solution with a strong technical foundation, clean architecture, and maintainable code. AI accelerates my development workflow—so you ship faster without compromising quality.
Solve the problems slowing your team down.
Need a second opinion on the front-end architecture, performance bottlenecks, scalability or some other type of complexity? I help teams identify root causes, make informed technical decisions, and define a clear path forward.
Improve what already works.
Legacy applications don't always need a rewrite. I help teams modernize codebases, introduce scalable architecture, establish design systems, improve performance, and reduce long-term maintenance costs without disrupting product development.
