Ivan Markovic
@ivanmarkovic1
I build full-stack products and AI developer tools that improve engineering outcomes.
SerbiaWhat I'm looking for
At Datatek doo Beograd, I build AI-assisted developer tools, including an OpenAI-powered code review tool that reduced turnaround time by 35% and caught 18% more style and logic issues than linting alone. I also architected a FastAPI and React internal tooling platform used by 200+ engineers across four product teams.
I connect frontend and backend work with product goals, from prompt management systems with audit history and automated evaluation pipelines to Kubernetes autoscaling on AWS EKS that handled 3x launch traffic without degradation.
Previously at EXLRT, I developed marketplace features for more than 1.5 million registered users, integrated recommendations that increased engagement by 28%, and led a zero-downtime migration to Stripe. At BlueGrid.io, I delivered Laravel, Vue.js, and MySQL solutions, including a multilingual CMS used across 20+ client sites.
