👋 Hi, I'm Aunish Kumar Yadav

Backend Engineer • Systems Builder • Network & Infra Enthusiast

⚡ Cyber • 🌐 Networks • ⚙️ Systems • ☁️ Cloud Infra

🧠 About Me

I’m a backend-first engineer who enjoys working close to the metal —
from raw socket programming and TCP/IP to distributed systems, telemetry, and cloud infrastructure.

I like building systems that:

  • Don’t collapse under load
  • Are observable by design
  • Fail predictably, not mysteriously
  • Scale without rewriting everything

🧱 Assume something will break. Design for it.

🛰️ What I Build

🔧 Backend & Systems

  • Custom HTTP servers (C, sockets)
  • High-throughput APIs
  • Event-driven systems (Kafka)
  • Clean, layered architectures

☁️ Infra & Networking

  • Dockerized production deployments
  • Telemetry & monitoring pipelines
  • TCP/IP, sockets, load balancing
  • Cloud-native & distributed design

🚀 Signature Projects

📡 Telemetry Monitoring System

(Datadog / CloudWatch–like)

  • Real-time system & network metrics
  • Alerting & ingestion pipelines
  • Built with observability-first design

🔧 HTTP Server in C

Raw socket programming

  • Built from scratch (no frameworks)
  • HTTP parsing & connection handling
  • Focus on performance & correctness
