What I'm looking for

I’m looking for a team where I can own end-to-end features, scale reliable APIs with strong DevOps practices, and push AI integrations (RAG/LLMs) into real products—building with clean architecture and measurable performance goals.

I’m a Full Stack Software Engineer with 2+ years of experience building scalable, production-grade web applications with Node.js, NestJS, React.js, and PostgreSQL. I’ve delivered high-availability systems achieving 99.9% uptime for 10,000+ users, and I improved API performance by 25% through PostgreSQL indexing, Redis caching, and middleware optimization.

I build reliable end-to-end features—from RESTful API design and microservices architecture to automated workflows and CI/CD. I engineered Digio-based KYC integration that removed manual document processing for 200+ monthly users, and I implemented asynchronous email/SMS notifications using BullMQ and Redis queues with zero impact on API response latency.

I’m also actively expanding my AI/ML integration expertise, including LLM APIs (Claude, OpenAI), RAG pipelines, and prompt engineering for intelligent full-stack systems. Recent work includes an AI Document Q&A RAG chatbot using Claude API, LangChain.js, and pgvector, alongside a Spring Boot ERP project with security, Flyway migrations, and Redis caching.
