About

Backend engineer with experience modernizing a large-scale procurement platform at Jio Platforms by breaking a monolith serving 35 business units into Spring Boot microservices, improving uptime and cutting report latency ~30%. Also built high-concurrency FastAPI systems (200ms at ~500 concurrent users) with strong security (JWT/OAuth2/RBAC), event-driven Kafka integrations, and reliability patterns like exactly-once delivery for ~1M monthly triggers.

Key Strengths

• Decoupled large procurement monolith into Spring Boot microservices (purchase order/invoice) for 35 business units
• PostgreSQL performance tuning via schema refactor + composite indexing; ~30% latency reduction in financial report generation
• Improved uptime and reduced MTTR using Prometheus/Grafana observability and service isolation
• Built high-concurrency FastAPI services (~200ms latency for ~500 concurrent users) using async patterns
• Implemented secure API access with JWT/OAuth2 + RBAC at an API gateway; OWASP-driven hardening and rate limiting
• Designed event-driven service communication with Kafka to reduce inter-service coupling during migration
• Ensured exactly-once execution at scale (~1M monthly triggers) using optimistic locking + Redis-based controls
• Reduced deployment drift by standardizing environment variables/config across staging and production
