Resume

• Stabilized and enhanced a legacy Classic ASP / VBScript Quality Control web application supporting manufacturing operations, fixing defects in serial-number generation logic, admin access control, and data-import tooling critical to QC throughput.
• Diagnosed and resolved production issues across the full stack — stored procedures, IIS configuration, database connectivity, and SQL Server restores — improving reliability of manufacturing and QC workflows.
• Authored migration assessments and risk analyses for modernizing the legacy Classic ASP codebase to ASP.NET Core 10, identifying technical debt, dependencies, and phased migration paths; published findings and approach at zakrevskyi.dev/blog/classic-asp-to-aspnet-core.

• Analyzed requirements with BAs/PMs, designed solutions, and participated in Agile/Scrum activities.
• Developed front- and back-end functionality for enterprise web applications using C#/ASP.NET Core (Razor/MVC), JavaScript/React/jQuery, integrated EF Core/Dapper data layers on SQL Server, implemented Identity and JWT for secure REST APIs.
• Led migration of legacy ASP.NET applications to ASP.NET Core (.NET Framework to .NET Core).
• Implemented background jobs with Hosted Services and Quartz.NET; automated SFTP file-processing workflows.
• Optimized SQL Server performance via query tuning, indexing, Dapper, and stored procedures.
• Applied IoC/DI, async patterns, interfaces, and clean architecture to improve maintainability and testability.
• Delivered via CI/CD (Azure DevOps, GitHub Actions); created branches, opened PRs, and resolved merge conflicts.
• Followed coding standards, conducted code reviews, and wrote unit/integration tests (xUnit/NUnit).
• Communicated status and risks to senior developers/PMs, and provided production support.
