Summary
👤
Senior🎓
Top SchoolKos Perun is a senior backend-focused software engineer with 5+ years building scalable Python/Django services and AWS-deployed microservices for healthcare, ads, fintech and publishing domains. He has designed and maintained hundreds of RESTful APIs, driven significant performance gains (e.g., 150% responsiveness improvements and 30% faster production flows), and integrated complex third-party systems like Stripe, Google Ads, and Campaign Manager 360. Comfortable across Django, FastAPI, Flask and async stacks, he pairs strong test discipline and CI/CD practices with hands-on mentorship and architectural spike research to guide technical decisions. Beyond web services, he built a cross-platform desktop transliteration tool used by translators worldwide (open-sourced) and produced a Python tutorial series, reflecting a dedication to developer education and open source. Fluent in Linux toolchains and (Neo)Vim, Kos blends pragmatic engineering with a researcher’s attention to detail—skills honed earlier as a published researcher and conference interpreter. Based in Toronto and open to new opportunities, he excels at turning complex domain requirements into reliable, well-tested systems.
