What I deliver: MERN stack MVPs ready for real users (React, Node.js, Express, MongoDB or PostgreSQL), frontend to deployment in 3-4 weeks. React/Next.js frontends with responsive UI and fast load times. Node.js/Express backends with RESTful APIs and third-party integrations (Stripe, Twilio, SendGrid, Google Maps). Database design and optimization (MongoDB, PostgreSQL, Prisma, or Mongoose). Authentication systems (JWT, OAuth, role-based access). AWS/DigitalOcean deployment with CI/CD pipelines. I've shipped dashboards, internal tools, and backend APIs for EdTech, SaaS, and marketplace platforms that systems teams rely on daily. Tech stack: React.js & Next.js Node.js & Express.js MongoDB & PostgreSQL Prisma & Mongoose, TypeScript, Tailwind CSS, AWS, Docker, Git. I value clear communication, maintainable code, and on-time delivery.
