At Pipex AI, I built and deployed a Stripe-based checkout system that reduced average checkout time by 40%, alongside a Gmail campaign feature using Google OAuth 2.0 for secure seller outreach.

Previously at BuildPro OGCS, I engineered RFQ, quotation, proforma billing, and buyer-seller communication workflows that improved transaction efficiency by 35%. I also built an admin panel that reduced manual administrative work by 40%.

I've built REST APIs, full-stack commerce platforms, and an AI customer-support chatbot handling 10,000+ daily queries. Using NestJS, MongoDB, OpenAI GPT API, and WebSockets, I helped reduce support response time to under 30 seconds.
