Tathagat Thapliyal

I build engineering teams and frontend systems that scale - spent years doing it at some of India's most demanding product companies. Currently heading frontend engineering at Simbian AI, where I'm building the UI layer for security infrastructure designed for the agentic era. That means shipping fast, maintaining zero tolerance for performance debt, and making complex security workflows feel intuitive, all at the same time. I led the full migration from Django to React, cut load times by 83%, and introduced AI-native development workflows across the engineering team. Before Simbian, I led web engineering at CRED, owning frontend delivery across multiple pods, scaling CRED Garage from 2M to 10M+ customers, and building platform systems that other teams depended on. I'm as invested in the team as I am in the code. I mentor engineers toward ownership, not just task completion. I've created courses, spoken at conferences, and consistently tried to give back to the community that shaped me. What drives me: systems that last, teams that own their work, and products that actually solve hard problems.
