Alex Coronell

I’m a Full Stack Developer with 4+ years building scalable architectures on AWS/Azure and delivering robust applications with Angular, React, Astro, and NestJS. I focus on cloud-native deployments, performance optimization, and technical SEO to create solutions that scale with real business needs.

In my recent work, I led end-to-end web infrastructure using modern architectures (Astro/Svelte), improving organic traffic by 50% through Core Web Vitals optimization and Technical SEO. I also built an end-to-end CRM system (PostgreSQL, Node.js, NestJS, Angular) and reduced manual workload by automating workflows with Python (Selenium, BeautifulSoup), Electron, and Firebase.

I care about operational efficiency and maintainability, so I integrate AI-assisted development workflows to accelerate delivery without sacrificing code quality. I also manage cloud infrastructure and deployments with AWS and Cloudflare, prioritizing stability, performance, and cost optimization—so teams can ship confidently and improve continuously.
