I’m a product-focused Full Stack Engineer with 5+ years of experience building scalable enterprise SaaS platforms. I specialize in designing high-impact backend systems, optimizing performance-critical APIs, and delivering reusable architecture that supports growth across many enterprise customers.

At Phenom People Pvt Ltd, I architected and delivered a Global Widget Management System used across 150–200 enterprise career sites, cutting manual configuration effort by ~70%. I designed and built 50+ REST APIs using Java (Play Framework), MongoDB, Redis caching, and Kafka-based sync systems, with a strong ownership mindset for reliable production outcomes.

I’ve driven measurable performance improvements end-to-end. I optimized panel APIs by integrating ElasticSearch-based selective querying, reducing ~100MB payloads to ~8KB and lowering CPU spikes, and I reduced CSS generation latency from 5–10 seconds to ~100–250ms by redesigning style processing and caching flow.

I also take pride in resolving complex production issues and mentoring others. I diagnosed and resolved a critical login/token validation issue, collaborated during migration from legacy Aurelia CMS to a modern Vue-based CMS, and mentored 2 junior engineers while guiding feature development for the revamped CMS architecture.
