Senior🎓
Top SchoolAlexander S is a product-minded Tech Lead and platform architect based in Espoo with nine years of experience building scalable geospatial and full‑stack systems. He combines hands-on backend and frontend development with strategic leadership, having led monolith decomposition, service cluster migrations to Helm, and a major DB migration from RDS to Aurora to improve scalability and cost-efficiency. Comfortable across AWS, Kubernetes, Terraform, Argo Workflows, PostGIS and modern CI/CD, he drives team autonomy by codifying infrastructure and developer workflows that reduce dependencies on central DevOps. His background in bioinformatics and machine‑learning research gives him an unusual edge in data-intensive problem solving and reproducible pipelines.
