01About

Dependable engineering for production systems.

My career began in historical archives, with cataloguing, digital preservation and my first PHP and MySQL systems in the public sector. It later evolved into systems that organizations depend on: case-management platforms for Public Prosecutor Offices, aviation systems, chemical industry, integration between the shop floor and enterprise systems (OT/IT), and railway telemetry. In these contexts, data problems, unclear boundaries and fragile integrations are not confined to code. They affect institutional workflows, logistics, production and decision-making.

My work combines hands-on software engineering and technical leadership, including solution design across multidisciplinary squads and the evolution of backend and enterprise systems with a focus on reliability, integration, traceability and maintainability. I stay directly involved in the code and architectural decisions, following how systems behave in production so they remain understandable, diagnosable and able to evolve.

Part of that path was in Australia, working in English with multicultural teams.

02Expertise

Software engineering for complex, distributed systems.

01

Backend Engineering & Distributed Systems

APIs, service boundaries, data access, and asynchronous processing in .NET, with backends designed for structural clarity, maintainable evolution, and consistent design decisions.

02

Systems Integration & APIs

Contracts, data transformation, and failure handling between courts, airline GDS/PSS, SAP, and external services. Integrations built for resilience and operational clarity.

03

Production Reliability & Observability

Instrumentation, production diagnosis, root-cause analysis, traceability, and controlled reprocessing across backend and integration flows, from first signal through recovery.

04

Industrial Data & OT/IT Integration

Industrial automation and OT/IT integration across SCADA/DCS, PLC, HMI, OPC UA and OPC DA/A&E, covering industrial data acquisition and process control with technologies including RSLinx, Allen-Bradley, ABB System 800xA and Aspen InfoPlus.21 (PIMS), and integrating plant environments with SAP and corporate systems.

05

Data Modeling & Structured Information

Data models, persistence, records, and query structures with semantic consistency, designed for reliable access and traceability across corporate information systems.

06

Technical Leadership & Delivery

Hands-on technical leadership of multidisciplinary squads, from product and technical discovery through solution design, code review, mentoring, automated testing and delivery, with autonomy inside architectural guardrails.

Core Technical Education

Federal University of Technology, Paraná (UTFPR)

My entire academic background was built at UTFPR, connecting electronics, telecommunications, industrial automation and software development.

This technical foundation went through digital logic, microprocessors, C/C++ programming and industry-applied systems before consolidating in corporate software development with .NET. It still shapes how I design systems, with attention to integration, traceability, real-world operation and long-term maintainability.

Softplan

Institutional scale ↗

I was technical lead and senior backend developer on SAJ Public Prosecutor Offices, leading technically first one and later two multidisciplinary squads. I stayed hands-on in .NET backend, microservices and institutional integrations across public prosecution offices, courts and digital channels, directing solution design within corporate architecture guardrails and following features from product discovery through engineering, quality validation and release. I led legacy-modernization initiatives focused on performance, scalability and reliability.

04Beyond

Beyond Engineering

Most of my work happens in front of screens. What keeps me grounded is the opposite: trails, open air, new places, and live music.

Outdoor, Nature & Mountain Biking

Trails and open country, on a bike or on foot. Physical effort, fresh air, and room to think without a deadline.

Travel, History & Culture

New cities, old archives, and how people live elsewhere. I like coming back feeling the world got a little wider.

Photography, Music & Live Shows

Capturing what catches my eye and standing in a crowd when the lights go down. Paying attention, through a lens or in the moment.
