Backend & Full-Stack Developer
TypeScript • Node.js • PostgreSQL • Vue.js • C/C++ • Embedded Systems
I'm a Software Development student at IFCE focused on building reliable backend systems, full-stack applications, and developer tools.
My main stack includes TypeScript, Node.js, Fastify, PostgreSQL, and Vue.js. I also have hands-on experience with embedded systems, developing firmware in C/C++ for the RP2040 using GPIO, ADC, PWM, I2C, UART, SPI, PIO, DMA, and hardware interrupts.
I enjoy understanding software beyond the interface: from business rules and API design to filesystem safety, automated testing, CI pipelines, and low-level hardware communication.
A local-first CLI for creating and maintaining reliable AGENTS.md project instructions.
- Published on npm as
@laurowd/adao - Scans project structure, languages, tools, scripts, and package metadata
- Detects outdated or inconsistent project instructions
- Generates deterministic project context without sending files externally
- Safely updates managed content with backups and concurrent-change protection
- Includes automated tests, package smoke tests, and CI on Node.js 18 and 22
Technologies: TypeScript, Node.js, Vitest, GitHub Actions
