Harmeet Singh

• Led the architectural decision for the USPTO download pipeline, designing a scalable approach to ingesting and processing large-scale legal IP data reliably. • Owns end-to-end backend responsibility for 3 core microservices powering the IP Proofread platform, improving service throughput and reliability since joining. • Achieved 85–90% test coverage across critical microservices, reducing production incidents and increasing deployment confidence across the team.

• Engineered 10+ backend features for a B2B platform serving 50K+ users, improving system responsiveness by 30% as measured by user engagement metrics. • Reduced backend API latency by 30–40% through targeted query optimization, strategic caching, and code refactoring — with zero infrastructure cost increase. • Drove test coverage to 90% using TDD practices, cutting production bug rate by 40% and significantly reducing post-release firefighting.

• Co-architected and led backend development of Nispand, a platform serving 100K+ users, delivering a 20% performance improvement through microservice redesign and caching strategy. • Built and optimised RESTful APIs and gRPC microservices that cut response time by 30% and absorbed a 40% traffic surge without degradation. • Implemented Go goroutine management patterns to power low-latency, high-concurrency microservices — improving overall system throughput by 35%.
