From integration to operation.
Jacquard brings financial operations into Slack, connecting banking, accounting and workplace tools. At Heini, I built the Node.js application and supporting integrations, with responsibility across application logic, workspace access, data processing and production delivery. The work connected the user-facing product with the services and background processes needed to keep it running.
My contribution
Application and integrations
Built transaction classification and purchase-order workflows using Node.js and Express, integrating QuickBooks and Plaid with PostgreSQL-backed reporting.
Access and data processing
Implemented role-based access and multi-workspace tenant logic, alongside scheduled bank and accounting sync jobs using Redis and BullMQ.
Deployment & observability
Used Docker, AWS and GitHub Actions for delivery. Supported zero-downtime deployments and structured logs and alerts to improve operational reliability.
