suvadeep@web:~ $ cat about.md

I'm a Senior Software Engineer with 5+ years at LTIMindtree — including two years onsite in the UK — shipping production MERN and Next.js platforms that serve 50,000+ daily users. I work across the stack: React/Next.js on the front, Node.js/NestJS and event-driven AWS on the back, with a bias toward security, performance, and clean architecture.

Lately I've been deep in AI-augmented and agentic development — Claude-powered workflows, tool orchestration, and spec-driven delivery — and in hardening cloud systems for regulated, fraud-sensitive domains. I also mentor junior engineers and enjoy the parts of the job that aren't code: scoping, threat-modelling, and keeping teams aligned across timezones.

# aspirations

  • Grow into technical leadership — owning architecture and mentoring engineers, not just shipping features.
  • Build AI-native, agentic systems — MCP, AI-automated workflows, LangChain & LangGraph — that make engineering teams meaningfully faster.
  • Go deeper on secure, event-driven cloud platforms — and on the systems-engineering layer beneath them: Kubernetes internals (control plane, data plane), learning K8s the hard way.
  • Keep learning in the open ↓ — dotfiles, side projects, and whatever I'm hacking on next.

I live in the terminal. My setup is a one-shot, idempotent `setup.sh` — keyboard-driven, no GUI dependencies, and re-runnable without breaking anything. It's all in my dotfiles.
