Hi, I'm Heertheeswaran V 👋
I'm a Lead Software Engineer with 8+ years of experience building backend systems, distributed services, and full-stack applications. Most of my work sits at the intersection of scalable backend architecture, third-party integrations, and AI-powered product features.
I care about writing clear, maintainable code that's easy to scale and troubleshoot, mentoring engineers, and turning ambiguous requirements into reliable production systems.
