Hi, I'm Ansh.

Round engine, socket layer, and settlement path for a live real-money product. Owned end to end.

• ▸Kafka event pipeline fans wager, result, and payout events across services with strict ordering and replay.
• ▸Idempotent settlement — retries, timeouts, and partial failures cannot double-pay.
• ▸Redis for hot round state, MongoDB for the durable ledger.
• ▸Rewrote hot paths and reshaped indexes for a ~30% lift in backend throughput.
• ▸Docker, CI/CD, and the monitoring around the whole stack.

Rewrote the pricing surface and moved the backend to end-to-end type safety.

• ▸Rebuilt the quote engine against faster reference data.
• ▸Migrated the REST layer to tRPC — no more contract drift between the Next.js client and Node backend.
• ▸Extended the PostgreSQL model and shipped the integrations that broadened payment corridors.

Led a cross-platform mobile product from empty repo to storefront.

• ▸React Native (Expo) across iOS and Android, plus the Express backend behind it.
• ▸Stripe, Razorpay, and Apple / Google IAP wired together with reconciled analytics.
• ▸AWS deployments and CI/CD; sat in on product calls when technical shape drove strategy.
