I build full-stack SaaS and POS platforms with React, Next.js, Node.js, and PostgreSQL.

What I'm looking for

I'm looking to build production full-stack products where I can own features end-to-end, contribute to scalable SaaS platforms, collaborate in Agile teams, and continue growing in backend systems, DevOps, and technical leadership.

I've built production SaaS, POS, and content platforms across Nexzem Technologies, Novanectar Services, and Aiking Solutions. My work spans React, Next.js, Node.js, Express.js, and relational and NoSQL databases.

At Nexzem Technologies, I built a multi-tenant POS platform serving 8+ retail verticals and 50+ active outlets, developed 70+ REST APIs, and implemented role-based access across four user roles. I was promoted to Team Lead, where I guided sprint planning and code-quality reviews for a six-member intern team.

At Novanectar Services, I delivered billing workflows, Google OAuth, dashboards, payment tracking, and admin panels for BissBill, helping reduce manual billing errors by 40%. I also built an editorial CMS used by 20+ writers and an intern-tracking system used by 50+ interns.

I've also created QRScan, a multi-vendor restaurant QR menu platform, and an SEO-focused cab booking website that grew organic traffic by 45%. I enjoy shipping practical, fast-loading products that improve real business workflows.
