About me

If you want to know more about my profile, please check in https://github.com/atmmdev

Node.jsNext.jsFull Stack DevelopmentFront End Software Development
I build scalable web products end to end — with deepest strength in React, Next.js, and TypeScript, and solid delivery on Node.js/Nest.js APIs, authentication, and cloud-based application work. My path started in UX/UI and Web Design, moved into UI Engineering, and matured into software engineering. That history still shapes how I work: clear interfaces, pragmatic architecture, and close collaboration with product and design.

Over 15+ years of experience building digital products, I have worked with international teams at IBM, BairesDev, and Globant, and on products for clients including British Petroleum, CNN Brasil, and Cars.com — across fintech, healthcare, e-commerce, media, telecom, and SaaS.

What I tend to own:
- Frontend architecture, Design Systems, and performance.
- Fullstack delivery with Nest.js/Node.js and modern React/Next.js.
- Enterprise modernization (legacy UI → React/TypeScript).
- AI-powered product features (LLM integration, automation, operator UIs).

Selected outcomes from my career documentation:
- 55% page-load improvement through React/Next.js optimization.
- 35% technical-debt reduction via structured UI refactoring.
- 45% load-time improvement modernizing jQuery → React/TypeScript.
- 56% faster frontend delivery through reusable component architecture.
- AI-powered editorial automation with GPT-4o, AWS Bedrock, FastAPI, and React.

Open to remote roles worldwide and international relocation. Based in Rio de Janeiro, Brazil.
