Available to hire
Hi, I’m Micael Carvalho, a Full-Stack Software Engineer with 8+ years of international experience. I started as a Software Tester and evolved into a versatile developer delivering reliable, scalable systems from concept to deployment. I work across the full lifecycle: backend architecture and API design, frontend/mobile development, QA automation, and DevOps. My main stack includes Flutter, JavaScript/TypeScript, Python, and C#, with strong experience in Docker, PostgreSQL, MongoDB, Git, and CI/CD.
I’m passionate about automation, open source, and AI-assisted development, and I enjoy collaborating with cross-functional teams to solve complex problems. I’ve built healthcare, automotive, and enterprise software solutions, and I’m open to remote or contract opportunities. Outside of work, I love travel and photography, maintain a vegetarian lifestyle, and stay active through running and long walks.
