About

I’m a Software Engineer with 3+ years of experience in distributed systems, cloud-connected integrations, and SDLC-oriented engineering. My main production stack is C#/.NET, Angular, messaging, AWS, Azure, SQL Server and MongoDB.

I work best where software engineering is treated as the full lifecycle of a system: understanding the domain, designing maintainable boundaries, implementing safely, supporting production, documenting context, and improving the process so future changes become easier rather than more fragile.

Professionally, my experience is grounded in enterprise software across education, financial services, insurance, and consortium contexts. Some public-safe examples include anti-fraud and document-validation workflows, legacy modernisation using the Strangler Fig pattern, identity and digital-signature integrations, customer and partner portals, and distributed platform support. Details are intentionally anonymised.

The direction I am building toward is large-scale digital transformation work: cloud engineering, distributed systems, platform quality, identity-aware integrations, SDLC traceability, and systems where long-term maintainability matters as much as feature delivery. My personal projects are practical proof points for that path, connecting C#/.NET, TypeScript, Azure, AWS, messaging, observability, infrastructure practices, and knowledge systems with a long-term move toward cloud and solutions architecture.

I write in both Portuguese and English, and I value thoughtful debate, clear communication, innovation, and the exchange of ideas between people.

Work

Software Engineer

VICERI SEIDOR

Feb 2024 to Present

Enterprise software consultancy across education, financial services, insurance, and consortium contexts. Work spans multiple client projects where technical delivery depends on understanding business rules, coordinating with stakeholders, iterating quickly, sustaining production systems, and designing maintainable integrations.

Segment

Education

Worked on large-scale education systems where traceability, business-rule clarity, controlled change, production continuity, and platform stability matter.

Segment

Finance and Insurance

Built and supported flows involving document validation, anti-fraud checks, biometrics, digital signatures, customer operations, partner portals, reports, imports, and financial process modernisation, including OCR PoCs across Azure, AWS, Google Cloud, and on-premise alternatives.

Segment

Consortium

Supported and modernised distributed and legacy systems in consortium-related contexts, balancing existing constraints with safer integration boundaries using strangler fig, event-driven flows, and cloud services.

Responsibility

Domain clarification and stakeholder alignment

Reverse-engineered undocumented workflows, clarified business rules with stakeholders, documented technical and operational context, translated process needs into implementation tasks, and helped reduce knowledge gaps between business, support, QA, and engineering.

Responsibility

Production support, cloud and value delivery

Handled debugging, log analysis, database investigation, incident resolution, technical onboarding, unit testing practices, and GMUD/change documentation in evolution contexts.

Key contribution

Cross-cloud OCR provider evaluation

Evaluated Azure Document Intelligence, AWS Textract, and Google Document AI for document-validation workflows, comparing feasibility, cost, precision, with fallback to support an architecture decision for STP flows.
