Rockstar🎓
Top SchoolPiotr Jander is a Senior Software Engineer based in Warsaw with 11 years of hands-on experience building cloud-native, full-stack systems across startups and enterprise teams. He has delivered end-to-end products and led a small engineering team at Quantiva™, designing features like an AWS-backed video processing pipeline and managing client-facing roadmaps. His background spans backend services in Java/Scala and Python, modern TypeScript frontends and React Native mobile apps, plus infrastructure and Kubernetes-driven CI/CD. At companies from neptune.ai to Box he focused on performance-sensitive back ends, SQL optimization, and ML-client integrations, showing a strong mix of systems and application-level engineering. Piotr combines formal CS training (University of Edinburgh) with business-oriented studies in accounting and finance, enabling pragmatic technical decisions that consider product and commercial constraints. He’s equally comfortable mentoring peers and diving into low-level optimizations, which makes him a dependable bridge between architecture and delivery.
