Hire the Best JavaScript Developers
in Argentina

Hi, I'm a Node.js Developer. I’ve been freelancing for 7 years and have also worked with two companies. I specialize in: JavaScript: (Node.js, Express, Next.js, React, Puppeteer, Playwright, Strapi) PHP: (Laravel, Livewire, Blade, Eloquent) Frontend: (HTML/CSS, Bootstrap, TailwindCSS, Flexbox) Databases: (MySQL, MongoDB) DevOps: (Docker, Linux, AWS) I only take on projects I know I can complete successfully, ensuring top-notch results and client satisfaction.

Today is the era of AI. And even long ago Aristotle said, "Whoever wants to answer a question must first formulate it correctly". And he showed that a false premise in a question inevitably leads to a false conclusion. Even with all the possible power of AI. Also, Charles Kettering, a famous American inventor and head of research at General Motors, said: «A problem well stated is a problem half solved.» I am the one who formulates problems for AI correctly. That is because I have 25+ years of experience and expertise in both mobile and web development, networking, leadership, and project management. As a Senior developer, I can deliver amazing apps and find opportunities more easily. Practices that set me apart: Automated testing techniques, Automation, Clean Code, Software Design, Architecture Principles and Patterns, Continuous Integration, Continuous Deployment, and so on. As a complete senior developer, I can deliver good software. What gives me speed and quality is following good principles and having a suite of automated Tests that can support a productive, Continuous Integration and Continuous Deployment pipeline. I can release much more often because I know how to use automation. I can integrate my code fast and automatically. I can deploy my app every time I check my code in. So I go much faster because I don't need to manually check every change. And I don't need to go through long days of manual QA. I know how to write good and fast automated Tests. And learn and follow architectural and design principles, object oriented principles, functional principles and so on.

I'm a SaaS Product Lead with 10+ years in UX/UI & Development — I scope, direct, and own full-stack SaaS delivery.
