Full Stack with strong Backend depth.
6+ years building and operating production systems across fintech, e-commerce and SaaS, from React applications to backend services supporting millions of users.
Node.js · TypeScript · React · AWS · GCP
Node.js and TypeScript services, REST APIs and third-party integrations in production, including financial flows on a platform with 7M+ active users.
React and Next.js product work alongside backend services: shared UI systems, frontend architecture and the APIs those interfaces depend on.
Incident investigation from logs and traces, production debugging, performance work and the operational details that keep services trustworthy.
AWS and GCP production environments, including CloudWatch, Cloud Run, Docker, CI/CD, and the work that follows a cloud migration.
Production problems: what broke, how I investigated, and what changed.
Production debugging · Fintech
On a financial platform with 7M+ active users, customers were blocked in onboarding by a provider error that did not match the original failure. I traced the request path and isolated the first error.
Invalid due dates stopped reaching the provider, and affected accounts had a recovery path.
Performance · E-commerce
After an AWS-to-GCP migration, a high-traffic e-commerce backend started timing out against the database under load. I tested pooling, caching, cold starts and autoscaling before proposing changes.
Pooling, caching and autoscaling changes followed the investigation, and the system handled traffic more reliably afterwards.
Frontend architecture · Healthcare
A US healthcare product needed a shared React foundation and a delivery path. In a short advisory engagement, I built the component system, micro-frontend integration and baseline AWS/ArgoCD workflow.
The shared frontend system and baseline infrastructure were in place. The client later discontinued the project after funding and team changes.
Dec 2023 – Aug 2026
Senior Backend Engineer · Contract / B2B
Backend engineer and technical lead for a financial-services squad on Sem Parar, a platform with 7M+ active users. I investigated production incidents, worked through API integrations with product stakeholders, and improved testing, documentation and onboarding.
Mar 2026 – Apr 2026
Senior Full Stack Engineer · Advisory / B2B
Short advisory for a US healthcare workflow product. I set up a shared React component system, micro-frontend integration, and baseline AWS/ArgoCD delivery.
Advisory engagement through Tecla. The client discontinued the project following funding and team restructuring.
Jul 2023 – Nov 2023
Senior Full Stack Engineer
Worked on NestJS microservices for analytical product routes. I designed Redis caching and invalidation, and raised automated test coverage above 85% on the core services.
Nov 2022 – Jun 2023
Senior Full Stack Engineer
Maritime logistics platform. I rebuilt a reporting microservice from Python to TypeScript to cut memory use and stop runtime failures, and built stateful Vue.js interfaces for operations teams.
Nov 2021 – Nov 2022
Full Stack Engineer & Tech Lead
Live commerce on GCP. Promoted to Technical Lead within six months; I owned Cloud Run services that handled 12,000+ concurrent users, mentored engineers, and established code review standards.
Aug 2021 – Nov 2021
Full Stack Engineer
Sole engineer on an interactive 2D React product, from technical and product decisions through production release.
Jan 2020 – Aug 2021
Full Stack Engineer
Built an ERP from scratch in React, Node.js, MongoDB and AWS S3, including Brazilian tax and invoicing integrations and automated document workflows.
I’m a Senior Software Engineer based in Brazil, with 6+ years of production experience across fintech, e-commerce, SaaS and logistics. I work in English (C1) with remote teams in LATAM and the US.
My work is Full Stack, with more time spent on backend systems, APIs, cloud infrastructure and production reliability.
I do best on teams that expect engineers to investigate real production behavior and take part in technical decisions, not just close tickets.

I debug from evidence, not assumptions.
I prefer simple systems before complex abstractions.
Observability should exist before production fails.
AI can accelerate engineering, but it does not replace understanding the code.
I would rather name a trade-off than hide it behind a best practice.
I’m open to Senior Software Engineer, Full Stack and Backend roles with remote teams in Brazil, LATAM and internationally.
