Backend platforms and APIs
The services and APIs behind mobile apps, SaaS products and internal platforms, built to stay maintainable long after launch.
C# · .NET · ASP.NET Core · EF Core · Dapper · REST
We build the backend systems that software products run on.
Kraliarg is a software factory based in Abu Dhabi. We design, build and run production systems for startups and growing companies, from the APIs behind mobile apps to data pipelines and AI agent tooling.

Data, ETL and reporting
Move, clean and report on data across databases and systems, from legacy migrations to the dashboards people use every day.

Agent workflows that do real work, with the evaluation harness to know when they don't.
Claude API · MCP servers · agent workflows · evals
About
Kraliarg is a software factory. We take a product from first idea to production and keep it running after launch. Every project is engineered by senior developers who write the code themselves, and is delivered tested and documented, ready for your team to own.
We are based in Abu Dhabi and work remotely with clients anywhere, in English or Spanish. Kraliarg was founded by Gaston Aguirre Gaona, a senior software engineer with more than ten years building .NET backend systems for product companies and enterprises.
