At QBS Co., I design and implement REST APIs for internal enterprise applications, including authentication, authorization, and role-based access control.

I develop full-stack features across Node.js, React, and Next.js, connecting API design and database modeling with responsive interfaces and deployment. I’ve also built real-time features using WebSockets for notifications, status updates, and live data views.

For multi-tenant systems, I’ve built and optimized PostgreSQL and MySQL schemas and queries, improving API performance with Redis caching, pagination, indexing, and query optimization.

I’ve integrated AI developer tools into my workflow and write unit tests with Jest and Vitest. Alongside my work, I’m specializing in AI application engineering, including RAG pipelines, vector search, and LLM tool calling.
