What I'm looking for

I'm looking to build scalable AI-powered products and reliable full-stack systems, applying LLM integration, automation, API development, and cloud technologies to meaningful business challenges.

I've built AI-powered full-stack applications at Swappsi serving 50,000+ monthly active users with 99.9% uptime. I architected Node.js and NestJS microservices processing 10,000+ requests per minute, cutting latency by 40%.

I integrate LLMs, AI APIs, automation workflows, RAG, and intelligent data processing into production-ready products. I also improved React and Next.js frontend performance by 30–35% and introduced testing and CI/CD workflows that increased deployment reliability by 50%.

Previously at Codrixo Technologies, I developed e-commerce capabilities used by 500,000+ monthly shoppers, improved checkout reliability, and reduced transaction failures by 25%. At Grow Tech, I built JavaScript, TypeScript, React, Node.js, and Python applications while improving system performance by 30%.

I enjoy turning complex business requirements into clean, scalable software and mentoring engineers to strengthen team delivery.
