Hi, I'm Pablo, an Argentinian full-stack developer and team leader specializing in Node/JS/TS projects. I've built production-grade applications with React, Vue, and Svelte while managing medium to large teams. I turn complex requirements into elegant solutions—and occasionally, I turn mate into code that actually works.
I stand prepared to assist with any challenges and answer your inquiries! With extensive experience in software development, my primary expertise lies in Laravel, and I'm proud to be a certified Laravel developer. Beyond that, I possess a broad spectrum of skills in web development. Please don't hesitate to reach out!
CTO and technical architect who builds scalable platforms and the engineering teams behind them. Author of _React — The Road To Enterprise_ and _Vue — The Road To Enterprise_. Speaker at React Summit, React Advanced London, and Vue Amsterdam.
Currently serving as CTO in the energy sector, where I consolidated three separate codebases into a single multi-tenant white-label platform — designing the full architecture from tenant-isolated data and custom domain routing to a granular RBAC permissions system built from scratch. I personally conduct penetration testing, and identified and fixed SQL injection and path traversal vulnerabilities in production. I resolved a critical performance bottleneck where PDF generation blocked the entire server for 60+ seconds, and built Playwright e2e test suites that automated quarterly financial verification — replacing hours of manual QA.
I build the full stack — React, React Native, Next.js, Vue, Node.js, TypeScript, PostgreSQL, MySQL, Docker, AWS — but what I bring beyond the stack is the ability to make hard architectural calls and follow through on them in production. I've established engineering functions from scratch, hired and mentored teams, and led the structured adoption of AI-augmented development workflows with defined standards and guardrails.
