At Macbease Connections, I build responsive, SEO-optimized React and TypeScript components for key product pages. I also develop Node.js, Express and MongoDB services in a microservices architecture, using Kafka for service communication and Redis caching.
I built a RAG Document Q&A Assistant that lets users ask questions about uploaded PDFs, with answers grounded in and cited to source pages. I designed its retrieval pipeline and streaming responses, reaching 85% answer accuracy on a 50-question test set.
On my Event-Driven Order Processing System project, I built order, payment and notification microservices that communicate through Kafka. I implemented idempotent event handling, retries and a dead-letter queue; load testing sustained 500 orders per second at under 200 ms p95 latency.
