## Experience
- Full-Stack Developer - Growmate / Accenture (client: IRN), May 2025 - Present, Oriente, Lisbon, Portugal.
  Own the payment domain end to end - Multibanco reference, MB WAY, credit card, TPA, cheque and cash across both online and in-person registry-office channels - together with exemptions, urgency fees, cost-rule pricing and automatic rejection on non-payment. Carry the largest share of the platform's payment backlog of any engineer on the team.
  Built the accounting-document layer that payments depend on: billing data and receipt issuance, collection documents, debit and credit notes, request proofs, and the cash-sheet register - a recurring source of correctness bugs across every registry lifecycle.
  Delivered a tracked security-remediation backlog of 20+ findings spanning authentication and session handling, upload validation, error disclosure and access control, alongside CVE-driven runtime and dependency upgrades and a migration to next-auth.
  Implemented optimistic concurrency control across the request and payment flows - versioning, guarded state transitions and idempotency - eliminating duplicate submissions and double payments under concurrent use.
  Built and maintain the three front-office areas - public, reserved and collaborator - with their backend-for-frontend services, collaborator authentication and profile-based context switching, plus the shared React component libraries consumed across the platform, built on Portugal's official AMA Agora government design system.
  Shipped multi-party request flows (representative nomination, action blocking for represented parties, participant summaries) and composite requests across all three areas.
  Refactored the shared service-step flow - the component layer every registry service renders through - standardizing data fetching and state handling so the public, reserved and collaborator areas consume one consistent contract instead of three divergent ones.
  Integrated Keycloak (OAuth 2.0 / OIDC) with Portugal's Chave Móvel Digital (CMD) government identity and the payment gateway; Kafka and Redis on the C#/.NET back end; GDPR-compliant analytics and cookie consent; Docker to Kubernetes delivery with Jenkins CI/CD; mentor interns and junior developers in an Agile/Scrum team.

- Full-Stack Developer - Neotalent Conclusion (client: VORTAL), Jun 2024 - May 2025, Lisbon, Portugal.
  On Operations Team II - the escalation tier that fixes the real underlying defects, not first-line unblocking - diagnosed, resolved and tested complex production incidents across C#/ASP.NET services and React UIs, minimizing downtime on a high-availability public-procurement platform.
  Shipped full-stack features spanning SQL Server data access through to the React interface, and refactored legacy modules for performance and maintainability.
  Built and optimised Azure DevOps CI/CD pipelines, and supported SLA compliance and incident-response efficiency alongside operations and infrastructure teams.

- Back-End Developer - VIA Consulting S.A. (client: Ageas Seguros (Millennium BCP, ActivoBank, SIBS, VISA)), Jan 2023 - Jun 2024, Lisbon, Portugal.
  Single-handedly rescued a stalled, non-functional integration project - rebuilt the C#/Java service layer connecting Millennium BCP and Ageas (REST + SOAP), delivered it to production, and restored a blocked banking-insurance data pipeline.
  Built and shipped online pet insurance end to end for Millennium BCP - a product the bank previously lacked - integrating it into the existing MBCP mobile app architecture, now live for customers.
  Developed automated batch programs for VISA that removed manual effort from report generation, and file data-mining solutions for SIBS that extract and analyse large-scale financial files.
  Automated detection and processing of financial files (movements, transfers) with Rundeck jobs persisting to MySQL / SQL Server, wrote NUnit tests, and managed delivery through Git, SVN and Azure DevOps CI/CD under financial data-security standards.

- Front-End Developer - Intern - Emvenci Business Services, Mar 2022 - Aug 2022, Lisbon, Portugal.
  Rebuilt UI components in Angular + TypeScript + SCSS following Atomic Design for reuse and visual consistency.
  Fixed bugs and improved front-end maintainability and scalability through a structured component architecture.
  Collaborated with the development team in a Git + CI/CD workflow to ship UI improvements.

- Software Developer - Intern - Arquiconsult, Mar 2020 - Aug 2020, Odivelas, Lisbon, Portugal.
  Built a back-office application with C#, ASP.NET Core and Entity Framework, including Razor Pages UI.
  Developed APIs consumed by a Xamarin mobile client and supported the mobile team on the cross-platform app.
  Integrated the Google Maps API (with jQuery) to map parks and trees, persisting to a SQL Server database.

## Writing
- Your CV parses worse than you think: building ATS-safe PDFs with headless Chrome (2026-08-31)

  Letter-spaced headings, wrapped URLs and two-column layouts quietly destroy a CV during text extraction. A generated pipeline with assertions catches all three.
