• Cut high-traffic API response time from 2-5s to ~100ms (~95% reduction) via query optimization, service redesign, and multi-layer caching. • Designed and rolled out distributed caching on Hazelcast (later migrated to Redis), reducing latency by 80% and significantly lowering database load. • Solved a concurrent duplicate-order issue by adding composite DB unique constraints and idempotent order-creation APIs, bringing duplicate-order incidents to 0 in production. • Implemented distributed tracing and observability using SigNoz (OpenTelemetry), enabling proactive detection and reducing MTTR by 40%. • Led delivery of the Industrial Catering feature from requirements and LLD to implementation and release, coordinating backend, frontend, mobile, and QA teams to ship on schedule. Took similar ownership for multiple later features. • Built the backend for the Tenant Administration Portal so tenant admins can self-serve onboarding/offboarding and manage feature-level access, reducing manual admin work and improving app adoption. • Delivered campus access and operations capabilities: dual-mode mobile access (in-app + Google/Apple Wallet) integrated with enterprise access management, and a Smart Parking module with tenant-managed vehicle allowlists, live slot tracking, and 3rd-party vendor integration. • Built a context-aware Support module that dynamically surfaces help categories based on user persona and location; reduced user issue resolution time by 45% within 3 months and improved tenant retention. • Wrote LLDs (DB and API schemas) for multiple features and helped peers through design walkthroughs, code reviews, and feature-wise Git branching/release strategies, reducing merge conflicts and making releases smoother.
