About

Backend-leaning full-stack engineer who has shipped production-critical data/reporting features at Walmart and built an end-to-end workflow automation product (FastAPI + React/TypeScript + PostgreSQL) deployed on AWS. Strong in performance/reliability engineering (parallel ETL, batch DB operations, indexing via EXPLAIN ANALYZE), secure API design (JWT/RBAC), and pragmatic incident-driven scaling (separating workers from API layer).

Key Strengths

• End-to-end delivery of production-critical enterprise reporting/ETL for retail & supply chain analytics
• Performance-focused backend engineering (partitioning, controlled multithreading, batch DB writes)
• Data modeling for analytics (Oracle star schema) and iterative query optimization under load
• API design with clean separation of concerns (thin controllers, service layer) in FastAPI
• Production-ready security implementation (JWT auth + RBAC enforced via middleware/dependencies)
• Frontend robustness and UX polish (React + TypeScript + React Query; prevents duplicate submissions; schema/runtime validation)
• AWS production operations with CI/CD (GitHub Actions -> Docker -> ECR -> EC2) and incident-driven scaling/architecture changes
