Summary
👤
Senior🎓
Top SchoolMichał Bultrowicz is a pragmatic lead developer and cloud software architect with 11 years of experience building reliable, asynchronous Python systems and data pipelines for both startups and large enterprises. He has repeatedly delivered greenfield MVPs and mission-critical integrations—ranging from HIPAA-compliant microservices and Kafka-driven task platforms to a tax-calculation single-page product serving Polish PIT-38 filers. Comfortable across the stack, he blends hands-on async Python, FastAPI, PostgreSQL and containerized deployments with infrastructure-as-code and CI/CD practices to make complex systems operable and testable. He’s shipped device-to-cloud solutions (drive-thru AI order-taking), orchestrated cloud migrations and automated network device configuration, demonstrating both deep technical ownership and cross-team collaboration. Notably, he designs for developer ergonomics—bringing services up locally with a single command and prioritizing testability and observability in legacy and greenfield codebases. Based in Katowice, Poland, he combines systems-level thinking with a bias for simple, controllable open-source tooling.
