My Role
I was a core contributor on Dashboardly, owning full-cycle development of major features end-to-end — from architectural design to production delivery. The platform pulls large volumes of data from the TikTok Shop API and surfaces it as fast, accurate analytics for sellers managing thousands of orders.
- Designed and implemented 5 feature-rich analytics modules: Sales & Profit Dashboard, Profit & Loss Analytics with multi-dimensional KPI comparison, Cohort Retention Analysis with heatmap visualisations, inventory management, and order management — built in Angular with NGXS state management
- Developed Customer Purchase Journey flow analysis with conversion rate tracking and retention statistics, processing thousands of daily transaction records
- Built and optimised NestJS backend services — controllers, modules, database schemas, and Prisma migrations — improving query response times through strategic indexing
- Engineered a BullMQ queue system with 15+ processors for parallel async imports from the TikTok Shop API (products, orders, inventory, FBT, statements), integrated Socket.IO WebSockets for real-time live metrics
- Implemented Stripe subscription management with webhook processing for billing events and a self-serve customer portal
