Incred Money Partners

B2B2C wealth platform: Bullion (digital gold/silver + SIP) and US Stock pricing/listing, Nest.js, Go, gRPC.

Project Overview

Software Engineer II on Incred Money Partners, the B2B2C superset of the consumer product. The codebase was already well written. I built the user-facing Bullion module (digital gold and silver, rewards by amount or weight, SIP) and later owned US Stock pricing and listing. SIP webhooks are queued so we stay inside partner rate limits of 20 requests/s (minimum 4 requests per transaction). Two daily windows — 12:30–2:30am and 8–10am — can burst up to 6109 transactions combined. Listings use an end-of-day last-price cron and stale-while-revalidate so clients see data immediately instead of waiting on a full refresh.

Key Features & Contributions

  • User-facing Bullion module: digital gold and silver, rewards by amount or weight, SIP
  • SIP webhooks queued to stay within partner 20 req/s limits (min 4 requests/transaction)
  • Two burst windows (12:30–2:30am, 8–10am) of up to 6109 transactions combined
  • US Stock pricing & listing: EOD last-price cron + stale-while-revalidate caching
  • Managed two small teams for US Stock integration and development
  • Refactored services so specific pieces can scale independently of the monolith
