At Cogni AI, I led the educational SaaS platform from technical planning and MVP architecture through production deployment, acquiring 100+ active users in month one. I built web applications with React and Node.js and improved content load times and core web vitals by 25% through MongoDB indexing and Next.js server-side rendering.

At Anyworky, I architected containerized Node.js and Python microservices and integrated Stripe Connect payment flows and Certn API KYC pipelines. I also built automated QA pipelines in GitHub Actions; at Medibank, I reduced system and API inference latency by 30% using asynchronous streaming, request batching, and Redis caching.
