Hi, I'm Chiranjeevi 👋

Senior Full-Stack Engineer | Performance Optimization | Angular, Node.js, Python (FastAPI) | Distributed Systems

LinkedIn Instagram GitHub followers

8 years crafting high-performance frontends → now architecting full-stack, distributed systems at scale. I design systems that are fast, resilient, and maintainable — from Angular micro-frontends to Node.js/FastAPI microservices backed by PostgreSQL and Redis.

🧠 About Me

I'm a Senior Full-Stack Engineer with 8 years of professional experience, currently deepening my expertise in backend engineering and distributed systems design. My background in high-performance Angular applications (v2–19) gives me a unique lens on system performance — I approach both frontend and backend with the same obsession for scale and reliability.

  • 🔭 Currently architecting: event-driven microservices with Node.js + FastAPI
  • 🌱 Exploring: distributed caching, database sharding & partitioning.
  • 💬 Ask me about: Angular Signals, RxJS patterns, Redis caching strategies, API design
  • 🤝 Open to: Systems design discussions, technical collaboration, and Lead Engineer roles

📚 Engineering Philosophy
  • Performance is a feature. Every millisecond of latency is a product decision.
  • Design for failure. Distributed systems will fail — build with retries, circuit breakers, and observability from day one.
  • Own the full stack. Deep frontend expertise makes me a better backend engineer; I reason about systems end-to-end.
  • Measure, then optimize. Profile before you guess. Instrument before you ship.
  • Document ruthlessly. Great code is readable. Great systems are explainable.

"The best systems are not the ones that never fail — they're the ones that fail gracefully and recover fast."
