Veteran Web3 Engineer
Veteran Web3 engineer with over a decade of experience designing, building, and scaling production-grade systems. I’ve led engineering teams and departments, driven technical strategy at fast-moving startups, and contributed hands-on to complex challenges across the Web3 ecosystem — from account abstraction and MEV protection to blockchain infrastructure and developer tooling.
I started my journey in 2015 as one of the first blockchain developers in Serbia, co-founding the technical team at GameCredits. Since then, I’ve helped build and scale products at organizations like Bloxico (Filecoin ecosystem), Pooky (gaming), and most recently Biconomy, where I served as VP of Engineering and Infrastructure Team Lead.
My core expertise lies in backend engineering (TypeScript/Node.js, Go, PostgreSQL, GCP, Redis), with hands-on experience integrating dozens of EVM-compatible blockchains. I also dabble in Solidity and smart contracts, and I’m passionate about improving developer experience in Web3 — always hacking away at new tools and personal projects to push the ecosystem forward.
Beyond titles and tech stacks, I thrive at the intersection of engineering leadership and deep technical work: building resilient systems, fostering strong engineering cultures, and turning ambitious ideas into shipped products.
When I’m not building, you’ll probably find me reading, hiking, or occasionally picking up a guitar.
