● Demonstrated success working on large, legacy codebases and evolving them toward modern standards.
● Experience with SQL (MySQL/MariaDB preferred), connection pooling, and data access performance optimization.
● Familiarity with GitHub-based workflows, unit testing (xUnit/NUnit), and Agile/Scrum practices.
● Comfortable with tools like GitHub, SonarQube, dotnet format, and Semgrep.

Nice to Have:
● Experience with Electron, Mobile App Dev or web-based .NET apps.
● Familiarity with frontend technologies such as TypeScript, Vue.js, or React.
