I design and implement high-impact solutions for global enterprises. My work spans full stack development, architecture, and automation, connecting technical decisions to measurable business outcomes.
Key achievements:
- Designed an RFID management platform for Grupo Boticário, processing more than 50K tags per day.
- Automated workflows for Dell global warehouses with a custom SRE platform used by international teams.
- Led migrations and modernization initiatives at Philips, improving performance and maintainability for distributed teams.
I believe in pragmatic solutions that balance innovation, maintainability, and data. Good code helps real people make better decisions.
Outside work I enjoy playing piano, aquarism, and brazilian Jiu-Jitsu.
Software Engineer
RemoteGrupo Boticário · Jan 2023 - Jul 2025 · Curitiba, Paraná, Brazil
- Designed and developed a ground-up RFID tag management platform for distribution centers (DCs).
- Processed 50K+ tags/day per DC, serving 1,500+ direct/indirect users.
- Integrated industrial printing systems and IoT devices, enabling real-time monitoring.
- Ensured end-to-end traceability for all products in group’s traceability pilot program.
- Deployed across 2 DCs, reducing inventory errors by 35%; now scalable to all group DCs.
- Elastic architecture handled 3x average demand spikes during promotions.
- Analytics with New Relic dashboards, enabling teams to: Identify bugs/operational failures, drive data-driven decisions and optimize logistics processes.
Programming Teacher
RemoteCubos Academy · Nov 2022 - Jan 2025 · Salvador, Bahia, Brazil
- Trained 800+ students across multiple cohorts, covering full-stack development and software engineering fundamentals.
- Conducted a cohort of 100 women as part of the iFood 1000 program, training women from scratch in technology with zero prior experience.
- Recorded a Java course, producing structured video content for asynchronous learning at scale.
- Mentored students through career transitions, helping them land their first roles in tech.
Software Engineer
RemoteiFood · Jan 2022 - Jan 2023 · Osasco, São Paulo, Brazil
- Contributed to the development and evolution of high-availability financial systems, ensuring the reliability and transactional integrity of the payments ecosystem. My work directly impacted sales conversion rates and platform stability during high-traffic peaks.
- Payments Engine: Architected and engineered the transactional processing core, designed to handle high throughput while guaranteeing data consistency at scale.
- Smart Routing & Fallback: Designed and implemented a dynamic payment routing system. The mechanism detects failures in acquirers or payment methods in real time and instantly redirects traffic to a fallback route, maximizing authorization rates and minimizing end-user friction.
- Penalty & Rules Engine: Developed a transaction penalty system to mitigate risks by applying complex business rules to block or restrict undesirable payment attempts based on flow behavior patterns.

- Worked on IST timezone.
Software Engineer
HybridPhilips · Mar 2017 - Feb 2019 · Blumenau, Santa Catarina, Brazil
- Led the global migration of a critical microservice from MongoDB to PostgreSQL, impacting 1,000+ developers across Philips’ teams in the Netherlands, India, and other regions. The refactor improved data consistency, query performance, and long-term maintainability.
- Contributed to the platformization initiative, modularizing the oncology monolith (part of Philips Tasy, used in 30+ countries) into microservices while upgrading the stack from Java 8 to Java 11. Collaborated with cross-functional teams to ensure seamless adoption.
- Supported frontend modernization by assisting Tasy teams in migrating legacy Delphi components to Angular, enhancing UI scalability for a system serving 5,000+ healthcare institutions worldwide.
Software Engineer
