At Paymate, I lead backend architecture for a payments platform processing 300,000+ transactions monthly, building REST and GraphQL APIs, React dashboards, real-time payment updates, and automated reconciliation workflows.
I've delivered full-stack fintech, e-commerce, SaaS, healthcare, wallet, and reporting products across Paymate, Shamla Tech Solutions, and HeapTrace. My work spans PostgreSQL and MongoDB schema design, Node.js services, responsive React interfaces, payment integrations, WebSockets, and AWS deployments.
I've improved page load times by about 30%, reduced deployment time from 20 minutes to 8 minutes, cut backend response times from 450ms to 270ms, and mentored four junior engineers through stronger code review practices.
