I’m a full stack engineer with 5+ years of experience building scalable, secure SaaS products across FinTech, EdTech, Healthcare, CRM, and ERP. I enjoy turning product ideas into production-ready systems, working end-to-end from responsive React/Next.js interfaces to robust Python (FastAPI/Django) backends and well-structured microservices. I focus heavily on clean architecture, performance, and security—especially RBAC-based access control, JWT/OAuth authentication, and multi-tenant governance. I’ve led architecture efforts, improved scalability and throughput significantly, optimized databases with indexing and caching (PostgreSQL + Redis), and mentored engineering teams to deliver faster with higher quality through testing and modern engineering practices.…I’m a full stack engineer with 5+ years of experience building scalable, secure SaaS products across FinTech, EdTech, Healthcare, CRM, and ERP.
