Hey there! I’m a full stack developer with years of experience building fast, secure, and scalable web and mobile apps from the ground up. I work across the full tech stack — from designing sleek user interfaces with React, Vue, or Nextjs to building powerful backends with Nodejs, Laravel, Django, or Spring Boot. I’m fluent in managing databases like MySQL, PostgreSQL, and MongoDB, and I integrate APIs, payment gateways, and third-party services (Stripe, Twilio, Firebase, etc.) with ease.
