Linux Servers Configured

9 systems currently running in production — all designed and built by me. I bring in contractors on a project basis when the scope requires it, coordinating the team from architecture to deploy.

I handle architecture, REST APIs, frontend interfaces, PostgreSQL schemas, Linux server configuration, Nginx, PM2, and SSL. Healthcare platforms, ISP management systems, institutional websites — I've shipped across all three sectors.

Based in Angola (UTC+1). Available for remote contracts and full-time positions globally.

What I deliver

  • Full-stack systems from scratch to production
  • Linux server config, Nginx, PM2, SSL
  • PostgreSQL schema design and REST APIs
  • Payment integrations and admin dashboards
  • English — professional level

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.

  • ▸Custom escrow payment system — no Stripe, built for Multicaixa Express and TPA
  • ▸Angolan BI number validation (9 digits + 2 letters + 1 digit) implemented from scratch
  • ▸Server-side rate limiting with Redis to block brute-force on auth routes

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).

  • ▸Monorepo, two isolated Laravel apps (Loja + SGA) communicating via internal API — failure isolation by design
  • ▸EMIS GPO integration: iframe flow ensures card data never touches the app server — PCI-DSS compliant
  • ▸SGA on PostgreSQL (complex relations, RBAC, audit logs); Loja on SQLite (simple tables, zero infra overhead)

ISP-Bié

Institutional platform & entrance-exam admissions system for a higher-education institute

Institutional website and admissions system for Instituto Superior Politécnico do Bié, a higher-education institute in Angola. Serves the public (courses, news, alumni portal, scientific journal, open tenders) and internal staff across seven distinct roles who run the entire entrance-exam pipeline — application intake, payment confirmation, document review and signing, exam room assignment, anonymized grading, and results.

  • ▸Custom-built role/permission system — normalizes Portuguese role names (accents, casing, typos) so roles like "Sub. Correcção" reliably match internally, with partial matching for sub-roles
  • ▸Anonymized grading pipeline: professors see only an exam code and grade form, never candidate identity — enforced at the query layer, not just hidden in the UI
  • ▸Self-hosted WhatsApp integration (Evolution API) with a custom Angolan phone-number normalizer, delivery tracking, and a retry queue for failed notifications

Internal company management platform

Internal management system for an Angolan ISP — covering clients, service plans, vouchers, technical support, and direct MikroTik router control. WhatsApp notifications for expiry alerts and billing reminders, with scheduled automation running around the clock.

  • ▸MikroTik RouterOS API over raw TCP/8728 — no third-party library, direct binary protocol implementation with full control over router state
  • ▸WhatsApp notification layer fully abstracted behind a service interface — swap Twilio, UltraMsg, or Z-API without touching any business logic
  • ▸Spatie Activity Log for immutable audit trail — every change records who, what, and when

Remote-hiring marketplace with escrow payments for the Angolan market

Remote-hiring marketplace connecting clients who post projects with freelancers who bid and deliver — plus a digital-products storefront (Loja), creator subscriptions, and a lightweight social feed. Escrow-protected payments in Kwanza via a local Angolan gateway and PayPal, structured proposal/negotiation/dispute workflows, and identity verification, built specifically for the Angolan market.

  • ▸Custom Angola payment gateway integration (AppyPay) — Multicaixa Express phone-push charges and pay-later payment references, with token caching, webhook handling, and polling jobs as a fallback reconciliation mechanism
  • ▸Dual-currency payment stack: AppyPay (Kwanza) alongside PayPal behind a clean strategy-pattern gateway interface
  • ▸Explicit finite-state machine governs the project lifecycle (published → negotiating → accepted → in progress → delivered → completed, plus disputed/cancelled branches) — centralizing business rules instead of scattering status checks

Corporate platform for an Angolan mining consultancy

Corporate web platform for an Angolan mining consultancy and training company, serving as the digital front door for a business selling technical consulting, mining equipment, and courses to clients across Angola, Mozambique, Namibia, and the DRC. Public visitors browse services, an equipment catalogue, courses, team and project case studies, and submit contact/quote requests. Staff manage every piece of content through a full back-office admin panel — no code changes required.

  • ▸Custom column-based i18n (no translation package) — translatable models store _en/_fr sibling columns resolved through Eloquent accessors with automatic fallback to Portuguese
  • ▸Lean role-based access via two purpose-built middleware, instead of pulling in a full permissions package
  • ▸Open-redirect hardening on the locale switcher — the Referer host is validated against the app URL before redirecting back

Internal stock & sales management system for a retail store

Internal stock and sales management system (a lightweight ERP) for a retail store selling clothing, footwear, cosmetics, accessories, and school supplies in Angola. Covers the full inventory lifecycle — goods receiving, stock adjustments, physical inventory counts, point-of-sale checkout, dashboards and reports — with role-based access for Administrator, Warehouse Manager, and Salesperson/Cashier profiles. Installable as a PWA.

  • ▸Ledger + cache consistency design: stock quantity is a denormalized cache kept in sync with an append-only movement ledger, avoiding expensive aggregation while preserving a full audit trail
  • ▸Deadlock-safe atomic sales: cart items are sorted before row-locking so concurrent sales sharing products in different order never deadlock; totals are always recalculated server-side, never trusted from the client
  • ▸Role-based data and field scoping enforced through Policies and API Resources — cashiers' queries are scoped to their own sales, purchase cost is hidden from the Salesperson role entirely server-side

What Clients Say

Words from the people who worked with me and use the systems I built.

"Fernanda was one of our standout students, and she came back to prove it — she built the institutional website and the billing system for ISPBié from scratch. Clean delivery, no supervision needed. That is the kind of engineer we are proud to say studied here."

"I discovered Fernanda through her content online. The more I watched, the more certain I became that she was the right person. Today, looking at everything she built for AngolWifi — the website, the online shop, the management system — I know hiring her was the best decision I made."

"Building a platform that handles healthcare professionals, contracts, and payments is not simple. Fernanda understood the complexity, asked the right questions, and delivered a system that is live and working every day. She owns the full stack — and that is rare."
