About

I build frontend systems that hold up under real production pressure -18,000+ IoT devices, live telemetry, and enterprise-scale data pipelines. At Wipro I've spent 5 years as the primary frontend engineer on a production-grade IoT platform spanning power, water management, irrigation, and smart parking. Key work: → Architected a centralised RxJS BehaviourSubject alert service - a deliberate pub/sub system design decision that collapsed N API calls per widget to 1 per refresh cycle. 25% measurable UI performance improvement. → Led the LoRa/OTAA onboarding of 6,000+ IoT field devices - Python payload decoding, ETL transformation, and real-time push to the IoT platform. → Designed secure REST APIs in Node.js and Python: JWT auth, OAuth 2.0, rate limiting, input validation, and structured error handling across distributed microservice layers. I've also shipped AI-powered applications using OpenAI's API and LLM integration patterns (Smart UX Assistant - live at itsmetrina.github.io), and implemented OAuth 2.0 + PKCE in a personal project (MiniSpotify) - the same auth standard used in fintech production systems. I'm actively studying system design formally - distributed systems, caching strategies, rate limiters because I believe it's the skill that separates senior engineers from great ones. I genuinely find it fascinating. Targeting: Senior SDE / Lead Frontend at PBCs and GCCs in Bengaluru (hybrid or remote) where I can own systems end-to-end and contribute to architecture decisions.

Work experience

Senior Software Engineer at Wipro, Dec 2025 - Present · 10 mos, Bengaluru · Hybrid, - Built and owned production Angular (10+) SPAs serving real-time telemetry from 18,000+ IoT field devices - power grids, irrigation, water management, and smart parking. Sole frontend owner for 4.5 years. - Architected a centralised RxJS BehaviourSubject alert service, a system design decision that eliminated N redundant API calls per widget, reducing to 1 call per refresh cycle. Delivered 25% measurable UI performance improvement under enterprise device load. - Led IoT device onboarding from scratch: 6,000+ LoRa/OTAA devices, Python microservice payload decoding, ETL transformation, and real-time data push to the IoT platform. - Designed and maintained secure REST APIs (Node.js + Python) with JWT authentication, OAuth 2.0, server-side rate limiting, input validation, and structured error handling across distributed microservice layers. - Took full senior engineering ownership post-KT departure, maintained and extended critical production architecture independently, demonstrating end-to-end reliability without title change. - Strengthened CI/CD pipelines; led peer code reviews enforcing security standards, performance patterns, and architectural best practices across the team. - Gained working knowledge of production Kubernetes architecture - data flow across masters, workers, load balancers, and MongoDB clusters in a live enterprise IoT environment.

Scholar Trainee - Frontend Developer at Wipro, Jul 2021 - Nov 2025 · 4 yrs 5 mos, Bengaluru · Hybrid, Part of the Wipro WILP. My core responsibilities were focused on the development of the Smart Cities IoT platform, which continued and expanded upon my band conversion to Senior Software Engineer.
