I’m a senior software engineer with 15+ years delivering production software across games, web, mobile, desktop, and interactive 3D/VR. I’m Unity certified, but I’m not limited to Unity. I’ve worked with both startups and established studios (Trailmix Games, Gram Games, Jam City, The Other Guys, Widow Games, Wannabe, The Whitebox), and I also take on freelance projects where I own the delivery end-to-end. Clients bring me in when they need someone who can take a vague brief and turn it into a working, maintainable product: scoping, architecture, implementation, testing, build and release, and production support. I’m comfortable jumping into an existing codebase, fixing what’s slowing it down, and leaving it in a better state than I found it. What I can help with: - Building new features or whole apps from scratch - Fixing bugs, performance issues, stability problems, and messy architectures - Integrations: third-party SDKs, payments, backend services, analytics - Automation and tooling to speed up delivery and reduce manual work - Game and interactive work (Unity/Unreal/WebGL) when that’s the right fit Tech and platforms I commonly work with: - Languages: C#, C++, C, Java, Scala, JavaScript/TypeScript, Python, PHP, HTML/CSS - Platforms: Android, iOS, Windows, macOS, console, AR/VR, plus hardware projects (Arduino, Raspberry Pi) How I work: I start by confirming goals and constraints, then propose a plan with clear milestones. I communicate early about risks and trade-offs, and I document key decisions so you can maintain the project after handover. If you share a brief, I’ll reply with a practical approach, a milestone breakdown, and an estimate.

Born, raised and educated in Buenos Aires, I developed a passion for Electronic Engineering. I am a thesis away from completing my Master's Degree. As my final project is linked to Switching Power Supplies and Embedded Systems, I decided to develop it while working in Power Integrations in Cambridge, UK. So far I have developed project linked to pure analog designs, embedded systems and switching power supplies. All this projects have one thing in common: the develptoment of electronics hardware design. If you are interested in my previous experience, a few examples of different works are left in my portfolio. If you are looking for someone how understand a lot about electronic theory, has worked in many areas, understands how to develop a cost-effective product, goes straight forward to results and never gives up, I might be your type of Engineer.
