I have 5 years of experience building production software, including work for one of Mongolia’s largest banks. I’ve also shipped live SaaS, e-commerce, booking, and streaming products used by real customers. I help startups and founders build, launch, and improve SaaS products with Next.js and TypeScript. I can build MVPs, add features, fix bugs, and integrate Stripe, Supabase, authentication, databases, and third-party APIs. I focus on clean, maintainable code, clear communication, and practical solutions that are ready for real users.

FAQ
Do I need to contact you before ordering?
Not for a small and clearly defined integration. If you need subscriptions, webhooks, multiple systems, roles, an unfamiliar provider, or you’re unsure which package fits, message me first.
What do I need to provide?
Please provide the current project, a clear description of the expected flow, the provider or API documentation, and test or sandbox credentials when required. Do not paste production secrets into the public order requirements.
Can you integrate Stripe subscriptions?
Yes. I can implement clearly scoped Stripe Checkout, subscription, webhook, and application-state flows. The exact package depends on how much billing logic and existing backend structure are involved.
Can you integrate Supabase authentication?
Yes. I can work with Supabase authentication, database access, sessions, protected routes, and related application flows when they are part of the agreed scope.
Can you work with an existing Next.js project?
Yes. This gig is designed for existing React and Next.js applications. I’ll follow the project structure and conventions where practical rather than unnecessarily rebuilding the app.
Do you build APIs from scratch?
This gig focuses on integrations and the server logic needed to support them. A small supporting endpoint can be included when required, but a full new backend or large API should be scoped as a separate project.
Will you handle webhooks?
Yes. I can implement and test webhooks when they are part of the selected package, including signature verification, event handling, database updates, and related application behavior.
Will you deploy and configure environment variables?
Deployment and environment setup are available as a Gig Extra. Otherwise, I’ll deliver the code and explain the required configuration.
What does a revision include?
A revision covers adjustments to the originally agreed integration. It does not include switching providers, adding unrelated endpoints, or creating a new feature.
What if the integration is larger than expected?
If I find that the requested flow is significantly larger or different from the selected package, I’ll explain the scope before additional work is done.
