Rebuilding sundarpaul-codes.com in a Turborepo monorepo — Next.js 16, Tailwind v4, and a component set I actually enjoy using.

What I've done

I build and own production systems end to end — logistics, ERP, and AI-driven platforms. Right now that means a transportation platform serving 500+ shippers and carriers: React and Next.js interfaces, NestJS services, MongoDB data layers, and two React Native apps, from schema design through CI/CD and release.

Someday

I want to

next

Distributed systems, properly

Move past 'it works at this scale' and actually understand consensus, partitioning, and failure modes from first principles.

An open-source tool worth using

Something small and sharp that comes out of a real problem I hit — not a framework, a tool.

someday

Teaching what I've learned

Writing and talks about the unglamorous parts: migrations, release workflows, keeping three clients in sync.

A product of my own

End-to-end ownership of something I chose, not something I was assigned.
