About

Senior .NET & React Developer · 11 yrs · Messy business logic → clean prod code. Remote-only. Available now.

I'm a Senior Fullstack Developer with 11+ years building production systems for US companies — fully remote. My core stack is .NET 8, ASP.NET Core, C#, React, Next.js, PostgreSQL, and SQL Server.
I've shipped software across logistics, healthcare, B2B SaaS, retail, and a media company that needed to recover from ransomware. The kind of environments where the business logic is complex, the requirements evolve fast, and "it works on my machine" is not an acceptable answer.
I don't wait for tickets. I understand where the product is headed and start building before anyone asks. Point me at the goal — I'll have the roadmap and the first commit ready.
You can check out my work and generate a custom CV based on your stack here: https://mxrcabrera-dev-portfolio.netlify.app/

Work Terms

Remote only. Async-friendly — I communicate clearly and proactively in writing. Available for short and long-term contracts. Rate: $40–60/hr USD depending on scope and duration. Hourly or fixed-price projects both work. I'm based in Buenos Aires, Argentina. I have 5+ years of daily experience working with US teams and I'm flexible on hours to match your timezone.
