At Raise Scope Technology, I design and ship production-ready full-stack applications using React.js, TypeScript, Node.js, MongoDB, and Spring Boot.

I've built 50+ RESTful APIs for user management, deposits, withdrawals, transactions, reporting, and admin operations. By optimizing MongoDB aggregation pipelines and compound indexes, I reduced high-traffic query response times from roughly two seconds to 200ms.

I architected multi-role CRM platforms supporting 1,500+ active users across five or more business workflows, with granular permissions, device controls, analytics, transaction monitoring, and an AI-powered in-app assistant. I also build real-time communication infrastructure with Socket.IO and own deployments, monitoring, debugging, and performance tuning for live systems.

My project work includes a Spring Boot and React food ordering system with Spring Security, MySQL, JPA, and Hibernate, plus a WebSocket-based chat application supporting group messaging, presence tracking, media sharing, and instant notifications. I work closely with product, design, and stakeholders to translate requirements into scalable systems.
