Hello, I'm Vaibhav 👋

DeveloperOrchestrator& Shipper

Full-stack developer. I build real-time systems, orchestrate distributed backends, and ship them to production.

SUMMARY.md
  • Full-stack developer with a focus on TypeScript and real-time systems
  • Comfortable owning a build end to end — architecture, backend, frontend, and deployment — rather than working on one layer in isolation
  • Drawn to problems with real failure modes: race conditions, dropped connections, retries — not just building features that work on the happy path
  • Currently deepening system design fundamentals, with a focus on distributed systems and backend architecture

FRONTEND, BACKEND, AND THE PARTS IN BETWEEN
