What I'm looking for

I'm looking to build and modernize secure, scalable products where I can contribute across architecture, frontend, backend, cloud infrastructure, integrations, testing, and technical leadership.

I've modernized Harvard Business School Online's in-house KMS using Django, DRF, Vue, REST APIs, and reusable modules, while improving performance, test coverage, E2E testing, and cross-framework Vue/React communication. I also integrated GetStream, LangServe, and AI-assisted workflows to support legacy modernization and high-quality delivery.

Previously, I helped build a secure cardiovascular health-monitoring platform at Vector Remote Care, delivering multi-tenant features, real-time capabilities, database optimizations, and AWS infrastructure work. Across 10+ years, I've built and architected web, desktop, eCommerce, community, and multimedia solutions using JavaScript, TypeScript, Python, PHP, React, Vue, Node.js, Django, and AWS.
