I'm Álvaro, a Cuban software engineer based in Montevideo and the creator behind ExagonSoft—my personal software and product brand.
I work across the entire product journey: finding the real problem, shaping the experience, choosing an architecture, writing the code, shipping the release, and learning from what happens next. My world includes responsive web platforms, cross-platform mobile apps, cloud systems, AI-assisted products, and interactive experiences.
My standard is simple: make it useful, make it trustworthy, and make it last.
| 🚀 Currently | Building independent products that turn complex workflows into clear experiences. |
| 🧠 Exploring | Applied AI, knowledge systems, developer tooling, and evidence-grounded automation. |
| 🤝 Open to | Serious product collaborations and difficult engineering challenges. |
|
A global bargain marketplace where timing creates opportunity. Simpler, faster, and better-organized person-to-person commerce. I lead engineering and development as a co-founder, shipping the experience across Android and iOS.

I care about interfaces people understand, architecture teams can evolve, responsible data handling, and products that create measurable value. The technology matters—but only because of what it enables.
If you're working on a meaningful product, navigating a difficult technical decision, or looking for an engineer who thinks beyond the ticket, I'd be glad to hear about it.
