I am a Senior Python Developer specializing in building high-performance distributed systems, real-time event-driven architectures, and production-grade AI/DevOps automation. Currently, I serve as the Backend & Infrastructure Lead for mission-critical enterprise applications at SMTlabs (for Vodafone Idea).
Beyond enterprise backend architecture, I have a deep background in advanced web automation, reverse engineering web systems, and contributing to open-source software.

- AI-Powered DevOps: Engineered a self-hosted LLM Code Review system inside air-gapped GitLab CI/CD pipelines, slashing manual PR review times by 40%.
- High-Performance APIs: Designed microservice architectures handling peak traffic of 195+ RPS with a 5ms P95 latency and an 98.5% cache hit ratio.
- Real-Time Pipelines: Built an end-to-end live notification streaming pipeline using PostgreSQL Triggers, Redis Pub/Sub, and Server-Sent Events (SSE).
- Data Throughput Optimization: Re-architected legacy scrapers to increase browser concurrency by 300%, significantly optimizing server resource utilization.
I love contributing back to the tools I use. Some of my recent contributions include:
- curl_cffi: Enhanced the core
Responseclass representation to natively display HTTP status codes, drastically improving debugging workflows for thousands of developers. - pyseto: Refactored security-registered claims helper methods to simplify token validation logic and eliminate code duplication.
I regularly write about backend performance, database optimization, and web system workarounds. Read my technical deep dives on Medium.
