Work Experience

Senior Fullstack Engineer Feb 2024 – Present

Biggerocks BV — Antwerp, Belgium (Remote)

Architected and built Sprks — a production-grade SaaS ERP for the diamond trading and atelier jewellery industry, covering inventory, accounting, production, CRM, and document management across two modules: Carats (diamond trading) and Jewels (atelier production).
Engineered a dual AI system: an intelligent document import pipeline that extracts and structures data from PDFs, images, and Excel files into ERP records; and an internal Copilot (powered by the Claude API) with 38+ tools that mirrors every manual action in the platform — executing batch operations in the background and giving staff complete natural-language control over the entire system.
Built the Desk module — a unified multi-channel CRM inbox (WhatsApp, IONOS email, Trengo) with AI ticket classification, auto-routing, a 6-stage Kanban pipeline, real-time WebSocket gateway, and cross-module sub-ticket linking between Carats and Jewels.
Designed an automated interest and debt recovery system — calculated accrued interest on overdue client balances, dispatched proactive payment warnings, and generated per-contact accounting reports — directly contributing to over $2M in recovered receivables.
Integrated live Rapaport diamond pricing, GIA/HRD/IGI certificate auto-fill, ZPL label printing for Zebra printers, BullMQ background workers, and role-based access control across multi-company and legal entity structures.
Sole engineer on a full TypeScript codebase — NestJS + Prisma + PostgreSQL API and Next.js + Redux + MUI frontend — 1,100+ files shipped and maintained end-to-end.
