About this service
Summary
FAQs
What frameworks do you use?
Elysia.js for flexibility, NestJS for structure-heavy projects. I can also work with custom or minimal stacks if needed.
Can you connect my API to my database?
Yes. I work with PostgreSQL, MySQL, MongoDB, and Redis. I can set up the schema, models, and migrations using ORM or raw SQL.
Can you help refactor an existing API?
Absolutely. I can step in to clean up architecture, modularise logic, improve error handling, or boost performance.
Do you write GraphQL APIs?
Yes — using tools like Apollo Server and TypeGraphQL. Let me know if you're going GraphQL-first.
Can you deploy the API for me?
Deployment to platforms like AWS, Render, Railway, or DigitalOcean is available as an add-on.
Do you offer ongoing API support?
Yes. I offer monthly retainer options for continuous API maintenance, feature extension, and integration work.
