Lisbon, Portugal · Allocated to the PRR programme — Portugal's Recovery and Resilience Plan

• ▸ Ensure the continuity and evolution of seven applications supporting PRR funding applications and benefits, balancing technological modernisation with the stability of live services.
• ▸ Own complex incidents end to end — from root-cause analysis to safe, documented remediation — restoring data consistency, preventing recurrence and protecting the operational integrity of the systems.
• ▸ Standardised the team's development environment with a multi-PHP Docker platform, automating setup and reducing discrepancies across legacy and modern applications.
• ▸ Enabled the team to diagnose production safely through read-only tooling, centralised logging and controlled evidence retrieval; the approach was later adopted for the helpdesk as well.
• ▸ Introduced AI into application support through automated ticket analysis and a knowledge assistant, accelerating incident triage and access to technical context across the systems.

Lisbon, Portugal · Allocated to Altamira — credit servicing and asset management

• ▸ In a small team, took cross-functional ownership of a platform supporting the full servicing lifecycle for distressed-credit portfolios and real-estate assets.
• ▸ Built and evolved modules for portfolio ingestion and normalisation; debtor, contract, collateral and property management; and workflows for collections, negotiation, regularisation and legal follow-up.
• ▸ Digitised the financial and real-estate lifecycle — payments, expenses, reconciliation, valuations, asset management and sales — centralising fragmented information and giving operations teams greater control.
• ▸ Implemented dashboards, reporting for banks and funds, access controls, audit trails and external integrations, strengthening data quality, auditability and portfolio decision-making.
• ▸ Covered every delivery stage — functional analysis, data modelling, backend, frontend, integrations, testing, release and production support — reducing specialist dependencies and accelerating response to the business.

Lisbon, Portugal · Software house — custom digital solutions for multiple clients

• ▸ Worked in a small software house, switching effectively across clients, industries and systems with different maturity levels, requirements and technical constraints.
• ▸ Built and maintained custom web solutions — online stores, websites, portals, learning platforms and internal systems — turning business processes into robust products that were easy to operate.
• ▸ Designed APIs, integrations and data models to connect platforms with external services, automate information exchange and support product evolution without compromising reliability.
• ▸ Supported solutions throughout their lifecycle, from analysis and architecture to development, release, maintenance and support, giving clients continuous technical ownership.

Natal, Brazil

Natal, Brazil · São Paulo-based travel startup — marketplace with real-time trip tracking

• ▸ Led the technical team and website development for a tour marketplace connecting customers with operators through an experience similar to a ride-hailing platform.
• ▸ Drove the web platform's evolution across tour discovery, sales and trip monitoring, including real-time route tracking through both the website and mobile application.
• ▸ Turned startup priorities into a technical roadmap, assigned ownership and followed delivery execution, aligning product, web development and the mobile experience.
• ▸ Worked across strategy and execution, making technical decisions and removing blockers so a lean team could validate and evolve the product quickly.

Brazil (remote)
