Summary
👤
Senior🎓
Top SchoolWitold Kupś is a software engineer with 9 years of experience specializing in JVM and JavaScript ecosystems, particularly Kotlin, Scala and Clojure, who focuses on functional and reactive programming approaches. He designs and optimizes NP-hard routing and logistics problems, combining algorithmic improvements with Kubernetes-based scaling to deliver production route-planning solutions for heavy transport. At interLAN he builds end-to-end routing platforms for dispatchers and drivers, drawing on earlier full-stack brokerage system work at Sygnity. Academically strong in automation, robotics and computer science (top grades), he blends rigorous engineering with a taste for market-driven thinking as a part-time stock investor. An affinity for optimization and constrained problems means he often tackles both code-level and architectural bottlenecks rather than only shipping features.
