Build what your app is missing
AI tools get you 80% of the way, but the remaining 20% - payments, real-time features, complex workflows, third-party integrations - is where things get hard. We build the features that require experienced engineering, integrating them cleanly into your existing codebase.
What we cover
Everything included in our add features service.
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
Transactional emails, in-app notifications, email digests, and notification preferences.
Search & filtering
Full-text search, faceted filtering, sorting, and pagination for data-heavy applications.
File handling
File uploads, image processing, document generation (PDFs, CSVs), and cloud storage.
Third-party integrations
Connecting your app with Slack, Zapier, Google Workspace, CRMs, and other business tools.
Common scenarios
Real examples of what our customers ask for.
Adding Stripe payments
Your app needs to accept payments - subscriptions, one-time purchases, or marketplace transactions.
Building an admin dashboard
You need a way to manage users, view analytics, moderate content, or configure your application.
Adding real-time features
Live chat, real-time notifications, collaborative editing, or live data updates.

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.
