At SmartRetail Malaysia, I own delivery of a multi-tenant analytics platform handling 1–2M events per day with sub-second freshness. I reduced p99 API latency by 30% by re-architecting AWS Lambda functions and optimizing PostgreSQL queries.
I improved throughput with caching, connection pooling, and read/write query separation. I also designed idempotency and retry mechanisms for event-driven pipelines, preventing duplicate processing during upstream outages.
I automated CI/CD and deployment workflows, cutting post-deployment incidents by 15% and saving 40+ engineering hours per month. I authored the team's Lambda error-handling and retry standard, supported its adoption across two services, and mentored incoming interns.
As a Software Development Intern at SmartRetail Malaysia, I re-architected a batch reporting workflow into an AWS Lambda event-driven pipeline, improving processing speed by 40%. I also built AstroNumy, a production mobile app with 1,000+ downloads and a 5.0 rating, and developed a toxic-span NLP pipeline that achieved 85%+ accuracy.
