Senior Software Engineer

I work on Nubank's Fraud Platform, supporting Pix fraud claims, refunds, dispute handling, and MED workflows in a distributed microservice environment.

I contributed to a Fulcro-to-React migration by implementing backend endpoints and migrating frontend functionality. I delivered backend services for BACEN's MED 2.0 initiative while preserving compatibility with previous workflows across distributed services.

I coordinated implementation details across approximately eight internal microservices and expanded multi-service automated test coverage through around 35 pull requests. I identified schema incompatibilities, service contract mismatches, field mapping issues, and business validation problems to improve pre-production validation.

I deliver production software using Clojure, ClojureScript, React, Fulcro, Kafka, Datomic, HTTP APIs, and CI/CD pipelines.

I worked on a healthcare CRM platform, leading frontend engineering improvements and contributing to AI product initiatives.

I used React, TypeScript, Python, FastAPI, Azure AI Foundry, and RAG technologies to support product development.

I developed enterprise CPQ software for Calix, supporting complex B2B networking product configuration integrated with Salesforce and Oracle CPQ.

I implemented frontend features for country-specific configuration workflows with interdependent product attributes. I helped evolve the frontend architecture using a Chain of Responsibility approach and established clearer step-by-step structures for business rules.

I collaborated directly with US stakeholders during product refinement meetings and worked in the Salesforce ecosystem. I earned Salesforce JavaScript Developer I and MuleSoft Certified Developer certifications.

My stack included React, TypeScript, GraphQL, Salesforce, Oracle CPQ, and AWS Lambda.

I worked in a frontend-focused software agency delivering web applications and customer-facing features for clients, including a telecommunications loyalty platform.

I led a major frontend reconstruction after identifying architectural issues affecting maintainability and product evolution. I presented technical debt risks to company directors and negotiated engineering time by linking architecture concerns to business priorities.

I helped scale the frontend team by interviewing, selecting, and onboarding an additional frontend engineer. I also implemented a RAG solution for a Petrobras subsidiary using Azure AI Foundry, React, and FastAPI.

I designed and delivered a five-session Generative AI workshop for non-technical professionals and presented an internal technical talk on Team Topologies, software architecture, and organizational design.

I helped launch the first version of a pharmacy delivery application used by real customers while working in the DoctorWeb/Farmazon context.

I delivered the complete mobile purchase journey, including the product catalog, address management, checkout, payment flow, and real-time updates through WebSocket communication.

I worked closely with backend engineers to evolve the MVP into a production-ready application. I also helped prevent an unnecessary Django-to-Flask migration by involving an external Django specialist and focusing the architectural discussion on trade-offs and implementation quality.

My stack included React Native, JavaScript, REST APIs, and WebSocket.
