Full Stack Engineer & Team Lead
Engineering judgment first, AI wherever it multiplies it. I lead teams that build scalable, AI-first full stack applications.
I build AI-first products on solid architecture, where AI amplifies good engineering instead of replacing it.
As a team lead I own client-side development end to end and work across the whole stack, from React and Next.js interfaces to Go services. I pair deep front-end architecture knowledge with AI-driven workflows to design features that scale, ship faster and stay maintainable as products grow.
Based in Novi Sad, Serbia. I mentor engineers, and I care about open source, frontend CI/CD, cloud and thoughtful UI/UX.
AI built into the product and the workflow, with engineering judgment making the final call.
Component systems and data flow designed to scale with the product and the team behind it.
Owning the client side end to end, setting direction and helping every engineer level up.

Leading the entire client side of the product and owning features end to end across the full stack. I design, build and maintain scalable features, evolve a custom fork of a major open-source form library, and keep React UI behavior and Go validation perfectly in sync. Modernized a large Next.js codebase to cut tech debt and speed up the whole team.

Built and maintained full stack applications for clients of every size. Designed front-end architectures for scale and performance. As Project Team Lead I worked with clients daily on scope and solutions, ran demos, made the architecture calls and took on the most complex front-end work. Trusted again and again to mentor interns.

One e-commerce app, B-World, built three times with React, Vue and Svelte, once for each integration approach. I measured every version with Lighthouse and Chrome DevTools and turned the results into a decision matrix that helps teams pick the right architecture for their product.
