What I do best Design and develop ASP .NET / ASP .NET Core applications Build and consume REST APIs (secure, scalable, well-documented) Create and optimize SSIS / ETL workflows for large and complex data loads Work with SQL Server (queries, performance tuning, stored procedures) Integrate systems like Microsoft Graph, SharePoint, Dynamics, Jira, GA4, and other APIs Diagnose and fix production issues, performance bottlenecks, and integration failures How I help clients Clear communication and practical recommendations Clean, maintainable, and well-structured code On-time delivery with attention to edge cases Honest feedback if something can be done better or simpler I’ve worked with startups, enterprises, and data teams, often on projects involving automation, reporting, data synchronization, and API-driven architectures.
