Hi there! I'm Piyush, and I like pulling systems apart to find where they actually break. I'm a full-stack engineer with a bias for the backend — the part that has to stay correct under concurrency and load, long after the UI on top looks finished.
Currently, I'm a Full-Stack Engineer at devx ai labs, where I own the pre-order journey for The Sleep Company's POS platform end-to-end — Shopify sync, cart, a three-tier coupon engine, and a payments layer spanning five providers. I act as technical lead for a 3-person pod, partnering closely with the EM and PM to scope and ship safely at a 251-store scale.
Previously, I've worked across a wide range of environments — from fintech platforms to Web3 startups — including EquityPandit, StepsStamp, and Codesdot Solutions. Before most of this, I spent a year and a half as a software engineer inside a stock-market advisory firm — and being that close to the subject matter pulled me into the market myself, on my own account: trading, mutual funds, managing my own portfolio. That's left me with a rare-for-an-engineer instinct for what actually matters in financial software: correctness under concurrency, auditability, and never quietly losing someone's money.
Outside of client work, I also run Merge Scheduler, a product I built to schedule GitHub merges and auto-revert failed deploys, and I write about the systems papers and production incidents I find genuinely interesting — like how Facebook scaled Memcached to a billion requests a second.
