Testimonials

Feedback from clients & collaborators

Reflecting my commitment to quality and reliability.

Working with Miguelangel was a great experience. He was always proactive, communicated clearly, and delivered consistently. He took complex technical challenges and turned them into clean, working solutions without needing constant oversight.

RK
Raina Kanjirappallil
Project Manager @ Connect Education

"Miguelangel joined us when our platform was essentially broken. Within 4 months he had it fully rebuilt, in production, and serving thousands of users. He also shipped an AI assistant that cut our support volume noticeably. Rare to find someone who can lead a team and still deliver at that technical level."

MS
Marilyn Solano
CEO @ Connect Education Β· Canada

Miguelangel's ability to own a problem end-to-end is impressive. From the AI integration to the platform rebuild, he approached every challenge with a clear head and strong technical instincts. A pleasure to work with.

SG
Shreyas Ganapathy
Project Manager @ Connect Education

Miguelangel was one of our strongest engineers and leaders. He took on the most complex projects, led teams effectively, and always delivered. His work on Trainme alone β€” rescuing a project that was months behind β€” showed what he's capable of.

AQ
Anderson Quezada
CEO @ Nexitus Β· Costa Rica

As a PM, Miguelangel made my job easier. He understood requirements quickly, flagged issues early, and kept the team aligned. The quality of his code and his accountability as a project lead set the bar for the whole team.

Jefferson Quezada
Project Manager @ Nexitus Β· Costa Rica

FAQ

Frequently Asked Questions

Answers to questions about my work and process.

What kind of projects do you work on?

Web apps, mobile apps, SaaS platforms, LMS systems, AI integrations and business websites. I work best when there's a real problem to solve and a business goal behind it.

Do you take on freelance work?

Yes. I take select freelance projects for clients who need someone that can own the full product β€” from design decisions to deployment. I'm also open to full-time opportunities.

How do you approach new projects?

Discovery first. I won't start coding until I understand the problem deeply. That means understanding your business, your users, and your goals β€” then proposing the right solution.

What's your typical project timeline?

Landing pages and business websites: 2–4 weeks. MVPs: 6–10 weeks. Full production platforms: 3–6 months. I'll give you a realistic estimate during our first call.

Can you work with an existing team?

Absolutely. I've led teams of engineers and I know how to plug into existing workflows. Whether you need a solo developer or a technical lead for your team, I adapt.

How can we get started?

Send me a message with a short description of what you're building. I'll respond within 24 hours to schedule a free 30-minute discovery call.
