Why I Write

Writing helps me think, and publishing keeps me honest. Each post is a snapshot of the questions I'm wrestling with and the data (biological or digital) I'm collecting along the way.

The Professional Snapshot

•
Current role: Director of Engineering, leading a 50+ person team building third‑party risk management software.
•
Origin story: Started as a frontend engineer obsessed with 60 fps interactions and shipped pixels. That eye for user experience now informs how I design AI‑driven workflows.
•
Conference talks: React India 2024, React Nexus 2024 and a growing list of meet‑ups where I share the good, bad and buggy of building with React and AI.
•
What I'm building now: Production‑ready GenAI features that respect latency budgets, compliance boundaries and, above all, user joy.

Guiding Principles

1
Data over dogma. Whether it's a pull‑request metric or a resting heart rate, numbers beat opinions.
2
Ship, then iterate. Every idea sounds clever until it's in the hands of a user.
3
Build for delight. The best technology feels like magic because it respects people's time.
4
Teach what you learn. Knowledge compounds when it's shared.
