Invoice & billing management for an internet provider
Internal invoice management system built for ISP BIE, handling client billing, invoice generation, payment tracking, and financial reporting for the company's internet service operations.
The company was managing invoices manually via spreadsheets, leading to errors, delays, and no real-time visibility into payment status or outstanding balances.
Full development: database design, backend logic, UI and internal deploy.

Healthcare professional hiring platform
Full-stack platform connecting healthcare institutions with freelance health professionals in Angola. Features a complete hire-to-payment flow: shift scheduling, escrow-based payments via Multicaixa Express, earnings dashboard, and a full administrative panel — all server-rendered and deployed on a Linux VPS.

ISP online shop + management system — two apps, one monorepo
Monorepo with two independent Laravel apps: an online shop (Loja) for end-customers to buy plans and vouchers, and a backoffice management system (SGA) for internal operations. They communicate via internal HTTP API — if the shop goes down, the SGA keeps running. Payments via EMIS GPO (Multicaixa Express + Angolan bank card).
