I design, build, troubleshoot, and improve backend systems using Node.js and TypeScript.

I can join an existing application to implement a feature, solve a production issue, improve an API, integrate an external service, or help structure a backend that is becoming difficult to maintain.

I can help with:

REST and GraphQL API development

Business logic and backend workflows

Node.js / TypeScript development

NestJS and Express.js applications

Database design and integration

Authentication and authorization

Third-party API and webhook integrations

Backend refactoring and architecture improvements

Production debugging and bug fixing

Performance and reliability improvements

I have experience engineering production SaaS platforms with complex business workflows, integrations, multi-user systems, and self-hosted infrastructure.

Engagements can range from a focused backend task or bug fix to the implementation of a complete feature or service.
