Dialvox is a platform for automating voice calls using text-to-speech (TTS) and DTMF capture. Businesses can register, schedule outbound calls, and send messages that are converted into speech using Amazon Polly. Calls are placed through Asterisk, and recipients can respond by pressing keypad numbers. I developed backend services in Express and PostgreSQL to manage user flows, call queues, and responses, and built the frontend in Next.js with TailwindCSS. The platform is commonly used to collect metrics like NPS via automated voice surveys.

PicoDev is a MicroSaaS development studio building internal tools and productivity apps for engineering teams. I led the architecture and development of multiple fullstack applications using Next.js, Express, TypeScript, and PostgreSQL. I also managed cloud infrastructure using AWS, Docker, and GitHub Actions, ensuring scalable deployments and maintainable pipelines. My role covered backend systems, frontend components, and DevOps automation.

UniJobs is a white-label job-matching platform developed as an undergraduate thesis to bridge the academic world and job market. Built with NestJS, PostgreSQL, and Vite, it features secure authentication, role-based access, and end-to-end testing. I collaborated with a team of students from Inatel and received mentorship throughout the process.
