About Me

I Build the
Future Stack.

With 10+ years of engineering experience (8+ full-time), I operate at the intersection of systems architecture, AI engineering, and product leadership. My work spans healthcare platforms serving 2M+ users to founding Zethra OS, a next-generation AI-native mobile operating system.

I don't just write code. I design systems, lead engineers, and ship products that handle real load in production — from async Kafka pipelines and distributed AWS infrastructure to local LLM orchestration with zero cloud dependency.

  • High-throughput backends: Node.js, Fastify, Kafka, Redis, BullMQ, AWS SQS
  • Cloud infra: AWS (7 yrs), Azure, Docker, Kubernetes, Ansible, GitHub Actions
  • AI systems: local LLM orchestration, multi-model agents, Qwen2.5-Coder, Qwen3.5, LLaMA3.2
  • Observability: Prometheus, Grafana, Loki, New Relic, ELK

Based in Bengaluru, India. Open to Staff Engineer, Engineering Lead, and Senior Engineer roles globally. Remote-first preferred.

Zethra OS
AI-Native Mobile OS

A next-generation mobile operating system built from the ground up with Rust and the Linux 6.x kernel. The centrepiece is ZethraAI: an autonomous immune system that monitors system health in real time, analyses crash data, and generates secure verified patches without human intervention.

  • Self-healing system that closes the gap between vulnerability discovery and resolution
  • Rust-first userspace for memory safety without the overhead of legacy stacks
  • Decentralised, privacy-by-design services built on Linux 6.x under Apache 2.0
