At TeamSystem Tirana, I shipped a third-party credit-risk integration for a cloud invoicing platform, taking it from PostgreSQL schema and NestJS API work through React scoring and entitlement screens to production.
I also took a stock and inventory module from proof of concept to shippable product. I built coordinator and executor microservices, a queue-driven extraction worker, and SQL-level stock calculations.
For product price lists, I engineered a CSV/XLSX import and export pipeline with typed validation, duplicate-SKU and stock-mismatch detection, and asynchronous file generation. I also extended public REST APIs used by partner teams.
I shipped e-invoicing and customer-communication features for the Italian market, and helped raise quality across two platforms by resolving 68 QA and production defects, stabilizing flaky end-to-end tests, and addressing accessibility issues.
