About

I’m a Full-Stack Engineer with 6+ years of experience building production web applications across React, Next.js, Node.js, TypeScript, FastAPI, PostgreSQL, Redis, and cloud-based systems. Recently, my work has shifted strongly toward GenAI product engineering — building LLM-powered workflows, RAG-based search, AI transcription pipelines, agent-style automations, and media processing systems using OpenAI APIs, embeddings, queues, and scalable backend architecture. I enjoy working at the intersection of product, frontend experience, backend systems, and AI. I can take an idea from UI/UX to API design, database modeling, async processing, AI integration, and production-ready delivery. Key areas I work on: GenAI applications using OpenAI, embeddings, RAG, agents, and structured outputs Full-stack product development with React, Next.js, TypeScript, Node.js, and FastAPI AI workflows involving transcription, summarization, captioning, search, and content intelligence Backend systems using PostgreSQL, Redis, BullMQ, queues, workers, and cloud storage Frontend-heavy product experiences with clean UX, real-time updates, and scalable architecture I’m currently focused on building AI-first products that solve real user problems — not just demos.
