Who I Am
I am a passionate Full-Stack Engineer & SaaS Builder based in Mumbai, India. I don't just write code — I design, build, and launch complete web products. I focus on turning complex ideas into high-performance, production-ready applications, bridging the gap between visual design and solid, scalable engineering.
I specialize in the React/Next.js ecosystem, Node.js backends, and integrating intelligent AI workflows. I believe in clean architectures, pixel-perfect visual execution, and shipping fast, scalable software that drives real value.
