Julián Andrés D'Ambrosio

I've spent 15+ years shipping enterprise software — from desktop systems for investment banks to national-scale government platforms — so when you're stuck on a bug, a slow query, or a messy codebase, I can usually spot the problem fast. I work across the whole stack: .NET and Node.js on the back end, React / Angular / jQuery on the front end, and React Native / Flutter for mobile. Over the last years I've built more than 20 enterprise projects end to end.

I also use AI-assisted workflows to move faster without losing architectural control.

How I can help you:

Live debugging — we get on a session and I stay with you until it works, whether it's a C# exception, an Entity Framework query, a React component, or a mobile build that won't ship.
Architecture and legacy rescue — Clean Architecture, CQRS/MediatR, SOLID; I'll help you untangle legacy code so it becomes something you can actually maintain.
Code reviews — clear, practical feedback you can apply right away.
AI-assisted development — set up workflows that raise both speed and code quality, in development and in business processes.

My goal is simple: to understand your problem and solve it, explaining each step in plain language so it is easy to follow.
