I help SaaS founders and product teams build, fix and finish Next.js and NestJS applications.
My focus is existing production codebases: bugs, unfinished features, TypeScript APIs, Stripe billing, authentication, databases, deployment and practical AI integrations.
Clients value my communication, attention to detail and work across multiple delivery phases. I define scope before coding, reduce regression risk and leave the codebase easier to maintain.
Share the issue, repository context and desired result, and I’ll recommend a fixed scope, milestones or an hourly approach.

FAQ
Can you build the entire AI SaaS from my idea?
Yes. If the scope is clearly defined, I can build the frontend, backend, database, AI integration, authentication, payments and deployment. Larger products can be divided into milestones.
Can you work with my existing AI SaaS?
Yes. I can review and continue an existing Next.js, React, NestJS or TypeScript application, including unfinished or AI-generated codebases.
Can you integrate OpenAI into my application?
Yes. I can implement OpenAI-powered product features and connect them securely through the backend instead of exposing API keys or sensitive logic in the frontend.
Can you add Stripe subscriptions?
Yes. Stripe subscriptions, checkout, webhooks and billing workflows can be included when they are part of the agreed package or added as an Extra.
Which databases do you work with?
I work with PostgreSQL and MongoDB, including Prisma-based applications.
Do you deploy the application?
Yes. Production deployment can be included in the agreed scope or purchased as an Extra depending on the package.
Should I contact you before ordering?
Yes, especially for Standard and Premium. Send the project idea, required features, current codebase if applicable, integrations and expected result so I can confirm the scope first.
