About Al

I'm a backend developer with experience specializing in system integration — connecting APIs and services into reliable, maintainable solutions that actually work in production.

My background spans consulting, academic, and research environments, which means I'm comfortable working independently, communicating clearly with non-technical stakeholders, and adapting quickly to whatever stack or process a team already has in place.

What I work with:

  • C# / .NET

  • TypeScript / Node.js
  • REST API design and integration
  • Remote — available immediately for short or mid-term contracts

I'm particularly effective on projects where systems need to talk to each other cleanly — third-party integrations, legacy modernization, or untangling existing backend architecture that has grown messy over time.

If you have a backend integration challenge and need someone who can onboard fast and deliver without hand-holding, feel free to reach out.
