Johnny Freire

Mobile Software Engineer since 2018. Before specializing, I ran a project through a startup accelerator and the full startup cycle, from idea to market. It was a lab that gave me perspective beyond engineering: how business, product, and technology connect in practice.

Today I work with fintechs and financial products. Flutter is my main tool, and I use Kotlin and SwiftUI when the project calls for it. Clean architecture, modularity, and observability are part of the daily work.

I also contribute to architecture decisions, support the team's technical growth, and work closely with product so engineering decisions make sense for the business.

Degree in Systems Analysis and Development, with specializations in Software Engineering and in Mobile Device Programming. I started my career as an auto mechanic, and that's where I learned to diagnose before reaching for a wrench.

Outside of fintech work, I keep projects tied to the automotive space. MuvAuto grew out of that interest and became my entry point into OBD. To learn hands-on, I've been using my own car as a lab: I'm building a few experimental projects with embedded Flutter, Kuksa, and VSS, using an ELM WiFi scanner. It's still early, but it's been a great learning experience, and I'm now also starting to look into AGL (Automotive Grade Linux).
