•Led end-to-end migration of a monolithic backend from Heroku to AWS, re-architecting into a scalable, service-oriented system that improved reliability, observability, and long-term extensibility.
•Designed and deployed web servers on AWS (ECS, RDS), enabling independent scaling, reducing system coupling, and significantly improving performance and throughput under growing user load.
•Built and maintained a full-stack e-commerce platform supporting 50,000+ active users across customer, support, and marketing systems.
•Designed scalable backend services for dynamic pricing, analytics, and experimentation, enabling long-term A/B testing and feature evolution.
•Shipped one-time purchases within a subscription-based model using cohort logic, Django APIs, PostgreSQL schema updates, and frontend analytics integration.
•Improved site performance by reducing asset load times ~70% and cutting Time to Interactive by 25% through frontend and asset optimizations.
•Accelerated engineering velocity by building CI/CD pipelines with GitHub Actions and strengthening test coverage for production-critical code paths.
