Senior🎓
Top SchoolJigar Jain is a Berlin-based software engineering contractor and former engineering manager with over a decade of experience building and scaling web products for startups and enterprise teams. He has led teams delivering high-throughput services and frontends—designing an event-driven RealEstate Leads system that generated ~€3.5M ARR and running a search service handling ~2500 requests/sec. Comfortable across TypeScript/React/Next.js, NestJS, Spring Boot, Elasticsearch, Kafka and AWS serverless tooling, he blends hands-on implementation with architecture and SLO-driven reliability improvements. He also introduced micro-frontend and internal UI component strategies, reduced tooling costs via A/B testing migrations, and improved incident noise and detection by two-thirds through pragmatic observability work. As a freelancer he focuses on helping early-stage startups build MVPs to secure seed funding, pairing product-aware engineering with rapid delivery. Colleagues see him as a pragmatic builder who translates business KPIs into measurable engineering outcomes.
