At E2XInfotech, I led full-stack development of a production HRMS SaaS platform for payroll, attendance, and leave management, serving 10+ client organizations. I also architected RESTful APIs and implemented JWT authentication and RBAC for multi-tenant organizational hierarchies.

At Aieze, I designed RESTful APIs and developed reusable frontend components. I optimized MongoDB schemas and aggregation pipelines, improving p95 query latency by 60% for high-traffic endpoints.

I’ve also built projects including FavoTrip, a travel booking platform with NestJS microservice-style architecture, and DownloadlyHQ, a content platform that achieved a 95+ Lighthouse score. My work spans web and mobile applications, APIs, and SaaS platforms.
