Nice to meet you, I'm Antônio
Full Stack developer and infrastructure enthusiast. I turn ideas into products that run in production, in whatever framework the project calls for, or plain vanilla when that fits better: interfaces, backends, desktop apps, scripts and the infrastructure underneath. Here you'll find my stack, my strengths and what I do beyond code.
What I do
I work end to end across the product lifecycle, from the interface to the infrastructure. These are the areas I work on every day.

Beyond development
My experience goes beyond code.
CloudflareThe whole Cloudflare stack, from DNS configuration to complex features.
DNS, SSL certificates, firewall rules and cache optimization. Cloudflare Pages for hosting, Workers for edge computing and R2 for object storage. Security policies, DDoS protection and global performance. Zero Trust, WARP for device management and VPN, services exposed with Cloudflare Tunnel, proxying services behind NAT, and Cloudflare Access policies.
Cloud & InfrastructureDeploying and managing resources on AWS, Railway, Vercel and custom VPSs.
AWS services such as EC2, S3, Lambda, ECS and CloudFront. Vercel and Railway for fast deployments, and custom VPS servers when more control is needed.
EnvironmentsEnvironments with Docker, Coolify, CI/CD tools and bare-bones VPSs.
Consistent environments with Docker and Docker Compose, and bare-bones VPSs set up from scratch when a project needs full control. Coolify, Portainer, Komodo and others for container management, and CI/CD pipelines with GitHub Actions, keeping development, staging and production uniform and reliable.
UI/UX DesignPrototyping in Figma, Google Stitch and Claude Design, turning concepts into functional interfaces.
Advanced prototypes in Figma with modern UI/UX principles, and Google Stitch and Claude Design to explore and iterate on interfaces with AI. Design systems for visual consistency and intuitive experiences, translated into code with Tailwind CSS, Motion and other modern front-end tools.
DevOpsAutomating processes, monitoring and continuously optimizing infrastructure.
DevOps practices to automate deployments, tests and integrations. GitHub Actions for CI/CD pipelines, and monitoring with Prometheus and Grafana.
Always learning
Technology keeps evolving, and continuous learning is essential for anyone striving for excellence.
These are the areas I'm actively exploring right now:
Artificial Intelligence
Integrating AI and machine learning into web applications to create smarter, more personalized experiences.
Distributed Architectures
Scalable systems with microservices, API gateways and private networks that handle heavy loads securely.
User-Centered Design
Refining interfaces through research, prototyping and usability testing to create intuitive, accessible experiences.
Mobile Development
Native and hybrid apps with React Native, bringing web knowledge to high-quality mobile experiences.
Sharing knowledge
Beyond learning, I believe in sharing knowledge. I'm always open to collaborating on interesting projects and exchanging experiences with other developers who love technology.
