About Marcelo

I build software for people who need it to work.

I'm Marcelo Perez, a full stack developer based in Buenos Aires, Argentina. I've spent the last 5+ years building web applications, mobile apps, and automated systems for clients ranging from early-stage startups to established businesses.

I started MP Consulting because I kept seeing the same problem: clients either worked with large agencies where they were a small fish in a big pond, or hired freelancers who disappeared after the first deliverable. I wanted to offer a third option — accountable, direct, and technically excellent.

When I'm not building client projects, I contribute to open source, stay current with the evolving web platform, and occasionally write about software engineering decisions that actually matter.

How I think

Values

Code quality isn't a luxury

Maintainable code moves faster in the long run. I write it that way from the start.

Full stack, real depth

I work across the entire stack — not surface-level familiarity. From database schema to pixel-perfect UI.

Communication is part of the job

Clients shouldn't have to chase status updates. I report proactively and keep everyone aligned.

Right tool for the job

I don't have a favorite stack I shoehorn into every project. The right technology is the one that solves your problem.

Tools of the trade

Tech stack

Technologies I work with regularly — not a resume-stuffing exercise.
