Fahim Muntasir

I’m a Full Stack Developer with production experience building SaaS applications using Next.js, TypeScript, Node.js, Express, Prisma, and PostgreSQL. I focus on secure authentication, reliable APIs, and polished UI experiences that work in real deployments.

I built SkillSync AI, a complete multi-role LMS with JWT authentication, Stripe payments, Socket.io real-time features, and 8 Gemini AI integrations. I implemented RBAC dashboards and workflow states, created REST APIs with pagination and middleware, and handled Stripe webhooks plus protected frontend/backend routes.

I also developed EcoSpark, a role-based sustainability platform with admin dashboards and payment workflows. From idea submission and moderation queues to premium gating and role-based REST endpoints, I bring end-to-end engineering—front to back—with strong attention to quality and teamwork.
