Remote

• Part of the squad behind ~40 modules of SIGA, the client's hospital management platform: clinical protocols, prescriptions, vital signs, bed management.
• Built and owns the clinical protocols REST API in Node.js/Express with TypeScript, serving versioned treatment checklists to doctors and nurses while keeping older versions traceable for audits as the active guideline changes.
• Designed the prescription validation engine in CQRS with a cached medication catalog in Redis, running dozens of safety rules (drug interactions, dosage limits, allergies) in under 300ms per prescription.
• Redesigned a synchronous integration between the main system and legacy systems that kept timing out under load into an event-driven RabbitMQ pipeline (idempotent consumers, dead-letter queue) that now handles ~200,000 messages a day with zero data loss, even at peak hours.
• Took a critical prescription screen from 1.5s to 180ms render time with list virtualization, server-side pagination, and React memoization (useCallback, useMemo, memo).
• Reverse-engineered an undocumented, 800-line legacy biometric engine: traced its WebSocket integration, found critical security gaps, and surfaced API endpoints nobody had ever written down, clearing the path for a new .NET/CQRS implementation.

Remote

• Built an LGPD compliance platform from the ground up (JWT auth, role-based access control, audit trails, encryption for sensitive data), serving several client systems at once with full traceability.
• In C#, ASP.NET MVC, Razor Pages, and Entity Framework over SQL Server, the job became making slow queries and high-volume reports actually fast.
• Wired REST APIs into legacy systems that had never exchanged data before, pulling information out of platforms that used to operate in total isolation.
• Helped model the data layer for a multi-system integration project, defining the structure and relationships a unified information flow needed.
• Ran on biweekly Scrum sprints, working directly with product and business on what got built next.

Campo Grande, Brazil

• Led the migration of GESCON (a legacy VB.NET municipal management system) to Angular and .NET 5, with the old system staying live in production through the entire cutover.
• Made the case for Clean Architecture, drove a one-month refactor, and walked away with ~900 lines of dead code gone and automated tests where there'd been none.
• Found a sensitive data leak in the GESCON API before anyone outside the team did, reported it, and shipped the fix that brought exposure down to the minimum necessary.
• File streaming for high-volume processing dropped report generation from 2s to 300ms, on full stack features spanning .NET, Angular, BPMN workflows, and legacy tax systems built on VB.NET and ASP.NET.

Campo Grande, Brazil

• Built patient management, scheduling, and electronic medical record modules for a clinic system using PHP (CakePHP) and JavaScript, optimizing MySQL queries and data modeling to keep read/write performance steady in production.
