Summary
👤
Senior🎓
Top SchoolMarkel Kaluhin is a Senior Software Engineer and Technical Lead based in Zagreb with 11+ years building full-stack web products using Python, TypeScript, serverless architectures and AWS. He has repeatedly driven performance and reliability improvements—examples include a 1500x throughput win on bulk operations, 76% fewer data-consistency bugs through strict typing, and reducing compute costs by over 40% via architecture changes. Markel pairs hands-on backend engineering (Lambda, DynamoDB, RDS) with UI modernization (atomic design, JS→TypeScript) and has built CI/CD and infra from scratch across teams. He excels at rescuing and reshaping legacy systems into scalable microservices and real-time platforms, and at coaching small teams to deliver faster with fewer bugs. Not obvious from the title: his background in economics and cybernetics informs a data-driven approach to backlog prioritization and resource optimization. He is open to collaboration and focused on solving tricky reliability, performance, and security challenges end-to-end.
