My Story

I'm a developer with over 20 years of professional experience, but the story started much earlier. I was around 8 or 9 when I wrote my first lines of code. I focus on web development, with a strong love for frontend, where code meets design and user experience. I can handle backend too, but I feel at home making interfaces that connect with people.

I also have a background in graphic design, which sharpened my visual sense and communication skills. I'm self-taught and endlessly curious, the kind of person who learns by exploring, breaking things, and fixing them better. I genuinely love technology. I can spend hours coding, experimenting, and building new ideas.

Born in 1980, I've witnessed the evolution of computing from the pre PC days to today's AI-driven world. Off-screen, I'm happily in a relationship and a father of two amazing young adults.

In short: a lifelong learner who codes with purpose, designs with intent, and never stops being curious.

Frequently Asked Questions

Answers to common questions about working with me

Whether you're a potential client looking to build a project or an employer exploring collaboration options, here are answers to questions I get asked most often.

For Clients

How long does a typical project take?

Timelines vary based on project scope. A landing page typically takes 1-2 weeks, while a full web application can take 4-12 weeks. I'll provide a detailed timeline during our initial consultation after understanding your specific requirements.

What technologies do you work with?

I specialize in modern web technologies: React, TypeScript, Astro, and Tailwind CSS for frontend, with Node.js, Hono, and PostgreSQL for backend needs. I choose the best stack for each project based on requirements, scalability needs, and long-term maintainability.

What types of clients do you work with?

I work with startups, small businesses, agencies, and individual entrepreneurs. Whether you need a portfolio site, a SaaS dashboard, or an e-commerce platform, I adapt my approach to fit your business size and budget while maintaining quality standards.

What's your work process like?

I follow a structured process: 1) Discovery call to understand your needs, 2) Proposal with scope and timeline, 3) Design/wireframes approval, 4) Development with regular updates, and 5) Testing and deployment. You'll always know exactly where we stand.

Do you provide ongoing support after launch?

Yes! I offer maintenance packages that include bug fixes, security updates, performance monitoring, and minor feature additions. Many clients continue working with me long after launch for continuous improvements and new features.

For Employers

Are you available for full-time positions?

Yes, I'm open to the right full-time remote opportunity. I'm particularly interested in roles where I can contribute to product development, work with modern technologies, and be part of a team that values code quality and user experience.

Are you open to part-time or contract work?

Absolutely! I'm available for part-time arrangements, fixed-term contracts, or project-based work. This flexibility allows me to contribute meaningfully to your team while managing other commitments. Let's discuss what arrangement works best for both of us.

What's your remote work setup?

I have a fully equipped home office in Argentina (UTC-3) with reliable high-speed internet, professional audio/video equipment for meetings, and experience working asynchronously with teams across different time zones. I'm comfortable with tools like Slack, GitHub, Linear, and Notion.
