Senior Full Stack Engineer / Technical Lead

I lead technical architecture and mentor a six-developer team. I have interviewed and helped hire four team members, onboarded five developers, driven architecture decisions, maintained technical documentation, and trained the team on agentic AI workflows.

I design and maintain NestJS and Express RESTful services backed by PostgreSQL, serving more than 20,000 monthly users at 99.9% uptime. I lead an Nx monorepo with five shared libraries across four applications, reducing duplication and unifying CI.

I implemented custom Claude Code commands and skills for Ionic libraries, Ionic applications, and NestJS services, reducing feature delivery time by approximately 30%. I also support containerized AWS deployments, event-driven messaging, CDN delivery, and Angular/Ionic mobile applications.

I delivered full-stack web and mobile functionality using TypeScript, Node.js, NestJS, Express, PostgreSQL, Angular, and Ionic. I contributed to RESTful APIs and services supporting more than 20,000 monthly users.

I worked with AWS ECR, ECS, SQS, SNS, and CloudFront to support containerized deployments, messaging workflows, and content delivery. I also contributed to shared Nx monorepo architecture and cross-platform Angular/Ionic applications for iOS and Android.

I developed a ReactJS ERP web application for an agricultural company operating 36 service units and serving more than 15,000 customers. I spearheaded the backend migration from Python to Node.js, approximately doubling throughput.

I built a React Native field application for on-site staff and led migrations of customer and employee applications from Ionic to React Native. I also engineered ScaleADM, a C++/Qt Raspberry Pi application that integrated truck scales with the ERP to automate weigh-in data capture.

I led the company's IT transition to Linux, reducing software licensing costs.

I developed C++/Qt and PostgreSQL software in a university research lab. The systems supported robotic milking operations and automated assembly lines.

I developed C++/Qt and PostgreSQL banking software for self-service terminals used by Brazil's largest public financial institution.

I built C/C++ and Qt software on Linux to capture results from medical laboratory diagnostic machines. The software made diagnostic data immediately available to laboratory staff.

Bachelor of Science in Computer Engineering.
