FAQ
Can you work with my existing codebase?
Yes. I work with legacy ASP NET Framework projects, ASP NET Core, MVC, Web API, Web Forms, and Razor Pages. Send me your repo or a zip file and I'll tell you what's possible within your timeline and budget.
How do you ensure work is on time and on budget?
I confirm scope and timeline with you before starting. All packages include a fixed delivery date, and I typically deliver 1-2 days early. If scope changes mid-project, I'll give you a clear price before doing the extra work — no surprise invoices.
What technology do you use?
ASP NET Core, C#, Entity Framework Core, Dapper, Web API, MVC, Razor Pages, SignalR, Blazor, React, MSSQL, MySQL, PostgreSQL, Azure, AWS, Docker, and Git. I pick the stack that fits your existing codebase.
What do you need from me to get started?
Access to your codebase via GitHub, GitLab, Bitbucket, or a zip file, a clear description of what needs to be built or fixed, and any API keys or database credentials I'll need to test. I'll reply with a kickoff checklist within 1 hour of your order.
