About
Hi, I’m Miguel Ángel Muñoz, a Full Stack Engineer who enjoys building scalable web applications, AI-powered workflows, and developer tooling. I’ve led design system initiatives, implemented RAG pipelines for document ingestion, and built cloud-native backends and frontends for multi-client SaaS products. I thrive in async-first teams and am comfortable spanning from product discovery through production rollout, with a focus on maintainable code, robust testing, and clear documentation.
I’m based in Brazil and have extensive experience working remotely with international teams, mentoring colleagues, and delivering rapid value in fast-paced environments. I advocate for accessibility, performance, and security (including HIPAA and ISO 27001 considerations) across projects, and I enjoy turning complex challenges into elegant, reliable solutions.
