I was the main engineer responsible for the architecture and development of a fintech payment platform built from scratch, replacing no-code solutions with a scalable proprietary system. I structured the full-stack architecture with Turborepo, Next.js, NestJS, and tRPC, delivered internal systems and front-end applications on AWS and Vercel, implemented Python automations with LLM usage, and integrated KYC and CI/CD workflows to launch the platform in under 90 days.

I worked as a senior full-stack engineer on a fintech platform for the secondary market of tokenized assets in a regulatory context aligned with Drex. I built scalable interfaces with React and Tailwind CSS, implemented and integrated REST APIs in C#, worked across front-end and back-end layers, and structured automated tests with Jest to increase delivery reliability.

I acted as Tech Lead in the engineering of a complex white-label platform, defining scalable architecture, technical standards, and project organization to support multiple implementations. I structured the foundation in a Turborepo monorepo, worked hands-on on the front end with React, Next.js, and Chakra UI, coordinated full-stack integrations with a Go back end through REST and GraphQL, and supported the delivery of more than four platforms across markets such as Dubai, Paraguay, Canada, and the United States.

I led the modernization of a SaaS product with React.js, Next.js, and Chakra UI, improving performance and user experience. I worked with cross-functional teams to turn complex requirements into scalable solutions, implemented automated tests with Jest and Cypress, integrated blockchain capabilities for secure document signing, and helped operate and scale the application on AWS and Google Cloud Platform.
