Summary
👤
Senior🎓
Top SchoolMark Barzali is a Senior Software Engineer and backend architect based in Brno with five years of hands-on experience building high-throughput, cloud-native systems using Python (FastAPI, Async), Go, and Rust. He specializes in monolith-to-microservice migrations, event-driven architectures, and SRE-driven performance improvements that have cut bootstrap times to seconds and allowed backend infrastructure reductions up to 50%. Mark consistently boosts developer velocity through tooling and modern language adoption—his FastAPI and Python 3.11 initiatives produced 20–30% app speedups and dramatically smaller scraping PRs. At companies from Seznam.cz to Heureka Group he has built resilient gateways and bidding/measurement platforms that handle significant load. He pairs a DevOps mindset with pragmatic architectural leadership, and quietly contributes to reproducible, observable platforms (tracing, metrics) that make complex systems operable. Outside of work he maintains a technical site and keeps experimentation in performance optimization and system coupling reduction central to his craft.
