At PwC SDC, I engineered a Redis caching layer integrated with Nest.js that cut database query latency by 40% and infrastructure expenses by 20%. I also integrated GPT-4, LangChain, and RAG pipelines into backend services for a customer query resolution system.
At Happiest Minds Technologies, I directed the migration of legacy PHP systems to Node.js/Nest.js microservices, improving performance by 30%. I also created an organization-wide scaffolding template that saved over 2,000 development hours annually.
Earlier, at Cognizant Technology Solutions, I developed menu management APIs and promotional tools for KFC Singapore & Philippines. Across my work, I’ve engineered distributed systems, data pipelines, and cloud-native services, including platforms handling 100M+ daily transactions at 99.99% uptime.
