About

Backend-leaning Software Engineer with ~3 years of experience building high-scale, production-grade systems. Currently at SHL, where I design and operate distributed backend services using Go and Node.js, handling high throughput, low-latency APIs, and large datasets. I’ve built systems involving distributed caching (Aerospike/Redis), database sharding, async processing, and localization infrastructure used across multiple international markets. I care deeply about performance, reliability, clean architecture, and writing maintainable code that scales with business growth. Previously interned at Optum, working on ML and data-driven systems. Awarded SHL’s Growth Mindset Award for driving ownership and delivering measurable impact.
