Summary
👤
Senior🎓
Top SchoolGuido Kollerie is a pragmatic Senior Python developer with 10+ years of freelance experience delivering backend systems for domains ranging from energy grid modelling and city open-data platforms to medical imaging and realtime transaction monitoring. He excels at modernizing legacy codebases—introducing idiomatic Python, type annotations, robust testing, and deployable packaging—while building cloud-native services with FastAPI, Celery, Airflow, and AWS/OpenShift/Kubernetes. Comfortable with Elixir as well, he focuses on reliable data pipelines, performant SQL designs and scalable architectures for mission-critical workloads. Based in Gelderland, he prefers on-site engagements within the Netherlands but is available for remote contracts, and brings a history of translating complex integration requirements into maintainable, production-ready solutions. An understated strength is his consistent role as a detailed code reviewer and architect-implementer who bridges product needs with hands-on delivery.
