# About: Antônio Miranda

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.

- **Modern Frontend**: React, Astro, Vite, Tailwind and integration with modern design libraries.
- **Robust Backend**: Scalable APIs with Bun, Elysia and Hono, and serverless functions on Cloudflare Workers, AWS Lambda and Azure.
- **Integrations**: Third-party APIs, payment systems and authentication solutions.
- **Performance**: Optimization and fluidity to craft exceptional experiences.

## My strengths

I'm passionate about creating exceptional experiences, where technical excellence meets a fluid user experience. The best technology is the kind that simplifies, connects and transforms people's lives.

- **User experience**: Intuitive interfaces and streamlined user flows.
- **Elegant solutions**: Translating complex needs into clean code.
- **Attention to detail**: From pixel precision to performance optimization.
- **User-focused delivery**: Every delivery shaped around how people will actually use it.

## Beyond development

### Cloudflare

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 & Infrastructure

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.

### Environments

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 Design

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.

### DevOps

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.

- **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.
