Add new features to your app
We build new features and integrate them into your existing codebase. This includes payment systems, user management, email notifications, search, file handling, and third-party integrations. Features are built with proper error handling, testing, and documentation.

Payment integration
Stripe subscriptions, one-time payments, invoicing, refunds, and billing management.
User management
User profiles, account settings, role-based permissions, teams, and admin dashboards.
Email & notifications

Frequently asked questions
Can you add features to code generated by AI tools?
Yes. We work within existing AI-generated codebases every day. We understand the patterns and integrate new features cleanly.
How do you scope feature work?
You describe what you need. We respond within 24 hours with a detailed scope, timeline, and fixed price. No surprises.
Can you build complex features?
Yes. Multi-step workflows, payment systems, real-time collaboration, integrations - we handle features that require experienced engineering.
Will new features break existing functionality?
We test thoroughly before delivering. If your app has tests, we run them. We also add tests for the new feature to prevent future regressions.
Do you build custom features or use existing solutions?
We choose the best approach for each case. Sometimes a library or service does the job perfectly. Other times, custom code is the right answer. We optimize for reliability and maintainability.
