What I'm looking for

I’m targeting a full-stack developer, front-end developer, back-end developer, or AI Engineer internship or full-time role.

At RideVelo, I contributed to end-to-end web application features, building functionality with React.js and integrating it with backend services. I also developed backend functionality with Node.js and Express.js and worked with PostgreSQL for application data.

I built DocuBrain, a RAG document intelligence platform that grounds responses in user-uploaded PDFs. I integrated LangChain and Google Gemini, added source-level citations, and implemented vector similarity search with PostgreSQL and pgvector.

On DocuBrain, I also moved PDF ingestion to FastAPI background workers, cutting upload endpoint response time by 97%. The deployed application uses Next.js on Vercel and FastAPI on Render.

I built FlowForge, a node-based workflow builder, with configurable node types and FastAPI graph-processing APIs. I used Kahn’s Algorithm to detect cyclic dependencies and added workflow history, autosave, and centralized state management with Zustand.
