Haris T.

Senior .NET/C# engineer with 12+ years building production fintech and SaaS systems. I have led engineering teams and delivered backend platforms, REST APIs, and full stack features on ASP.NET Core, EF Core, SQL Server, Blazor, and React, deployed on Azure and AWS. Where I add the most value: Payments and financial data platforms: payment orchestration, financial data pipelines, and the backend services around them. Legacy modernization: moving older .NET Framework and MVC applications to modern .NET, with tests and safe rollouts. Observability: tracing, metrics, and logging with OpenTelemetry, SigNoz, and Grafana, so production problems are visible early. Workflow automation: API driven and Power Automate based automation for business processes. AI assisted engineering: I use Claude Code and Cursor every day, and I review and own every line that ships. I have also built agentic pipelines on the Claude, OpenAI, and OpenRouter APIs, including model routing and cost tracking. My master's degree focused on machine learning and deep learning, so this is not a recent trend for me. How I work: clear scope up front, regular written updates, small reviewable changes, and honest estimates. I am comfortable owning a module end to end or leading a small team. Good fits: senior .NET backend roles, payment and billing systems, API integrations, modernization projects, and fast MVPs that still need to be production ready.
