Product engineering
I turn unclear business problems into systems people can actually use, covering requirements, trade-offs, interfaces, APIs, and delivery.
Software engineerBrazil · Remote
I build things.Mostly software.
Always with intent.
Mobile products, useful systems, and the kind of problems that only show up after everything was supposed to be working.
01 Practice · What I do
Engineering that survives contact with reality.
Mobile products
React Native and TypeScript across iOS and Android, grounded in production maintenance rather than framework theatre.
Frontend systems
Next.js, responsive interfaces, motion, transactional communication, and the reusable structure behind polished product experiences.
02 Method · How I work
Less theatre.
More signal.
Understand before building
The first solution is usually just the fastest way to discover the real problem.
Make the complex legible
Good engineering leaves fewer mysteries behind, both in the product and in the code.
Care about the last 10%
Loading, failure, interruption, recovery. The unglamorous states are still the product.

01Popstand
Healthcare operations leadership
Led frontend, backend, and mobile delivery for an international healthcare client. Broke large Jira items into parallel workstreams, more than doubling monthly throughput while preserving peer review and integration quality.
- HL7-based reporting across multiple US states
- Privacy-sensitive laboratory workflows
- Client communication and technical coaching
02Popstand
A simpler way to create on-chain
Built the initial structure of an NFT marketplace across frontend, application APIs, deployment, and stakeholder communication. Designed a validated prototype that presented dependent blockchain operations as one guided creation flow.
- Collection and asset creation
- Third-party Web3 APIs
- Feasibility before premature resilience
03Sortium
Frontend systems with sharp edges
Built responsive, accessible, motion-led interfaces for established and experimental digital products. Designed a composable transactional-email system driven by reusable blocks and backend-provided content.
- Gmail, Outlook, and device validation
- CSS animation and responsive UI
- Registration and error-state ownership
04Entermotion
Production mobile, without mythology
Helped build and evolve provider- and patient-facing React Native applications across iOS and Android, spanning scheduling, messaging, forms, billing, payments, and other healthcare workflows. Worked across GraphQL/Apollo data flows, performance, native behavior, application lifecycle, and difficult production issues.
- React Native and TypeScript
- iOS + Android / native debugging
- GraphQL and Apollo Client
- International collaboration in English
Specific enough to show the work. Careful enough to respect the people who trusted me with it.
04 Lab / Experiments
Small ideas.
Sharp tools.
No roadmap.
RPG Session Board
A focused space for shaping tabletop sessions: keeping ideas, moving parts, and the inevitable chaos visible enough to actually use at the table.
Campaign notes deserve better than archaeology.Playdate
A local map for parents looking for places that are genuinely kid-friendly — with useful details about play areas, monitors, age ranges, pricing, and recent experiences from other parents.
Their play. Your date.05 About
I’m interested in the whole thing.
Senior Mobile & Software Engineer with 8 years of experience building and scaling cross-platform applications for international clients. Specializes in navigating complex technical constraints, regulatory integrations (such as healthcare workflows and HL7 standards), and bridging engineering execution with product clarity.
I like understanding the system, finding where it bends, and building something simpler, reliable, and pleasant to use. Outside work, the same instinct usually turns into a D&D campaign.
