Aryan Khanijo — Senior Software Developer specializing in backend systems, scalable architectures, and full-stack applications
Hi, I'm Aryan Khanijo — a Senior Software Developer specializing in backend systems, scalable architectures, and full-stack applications. I architect systems, automate workflows, and build infrastructure that scales cleanly over time.
With expertise in Node.js, NestJS, Next.js, PostgreSQL, and Docker, I build production-grade systems that are maintainable, well-documented, and optimized for long-term growth. Currently based in India, open to remote opportunities worldwide.
