At Enterprise Software & Product Studio, I architected and deployed an internal Agentic AI RAG Assistant with Python, FastAPI, LangChain, pgvector, and Claude Code, reducing document search and retrieval latency by 85%.

I also led frontend and API engineering for a high-concurrency event ticketing and queue platform, achieving sub-50ms seat-hold locks for 50k+ concurrent users with zero overselling. I engineered Next.js 15 interfaces and Node.js microservices that maintained 99.99% availability across 10M+ monthly transactions.

At Digital Product Innovations, I built multi-tenant SaaS dashboards and real-time messaging widgets, and improved flagship web apps’ Google Lighthouse scores from 62 to 98+. Earlier, as a Software Engineering Intern / Associate at Tech Tech Solutions, I developed accessible React component libraries and worked on PostgreSQL migrations and Node.js REST endpoints.
