Software Engineer who designed the Verified Dataset Feature that closed a long-standing data-governance gap on an international certification platform, and owned the integration layer connecting that platform to its external partners in production. Five-plus years turning brittle legacy systems into Clean Architecture .NET/React platforms built to keep running after the original developer leaves the room. Strongest at walking into an undocumented integration mess and making it boring — reliable, tested, and shipped.
FAQ
Do you provide the source code?
Yes, you will receive the full, clean source code for all deliverables, including frontend, backend, and database scripts.
Can you fix bugs in my existing .NET or React project?
Absolutely. I can diagnose and resolve issues in existing codebases, fix performance bottlenecks, and implement new features without breaking current functionality.
Do you handle deployment to AWS or Azure?
Yes, I can deploy your application to AWS, Azure, or other hosting providers. I also set up CI/CD pipelines for automated updates. This is available as a Gig Extra or as part of the Premium package.
Can you integrate third-party APIs (like Stripe, Auth0, etc.)?
Yes, I have extensive experience integrating RESTful APIs. Whether it’s payment gateways, authentication services, or external data sources, I can connect them securely to your application.
What if I need changes after the order is completed?
I offer post-launch support and maintenance packages. Please contact me after delivery to discuss ongoing support needs, or you can purchase "Additional Revisions" if the changes are minor and fall within the original scope.
Does the price include hosting and domain costs?
No, hosting and domain costs are paid directly by the client to the provider (e.g., AWS, Azure, GoDaddy). My fee covers development, coding, and server deployment only. I can help you estimate the monthly hosting costs based on your needs.
