David Gitahi

I build modern web applications with secure payment systems and scalable backend APIs.

If you're launching a SaaS, fintech product, or any platform that handles transactions, I can help you build it reliably from frontend to backend.

My stack

Frontend: React (responsive, fast UI)

Backend: Node.js / Express

Database: MongoDB / PostgreSQL

Payments: M-Pesa, Stripe, API integrations

What I deliver

• Fullstack web apps (React + Node backend)
• Payment integrations (M-Pesa, Stripe, custom APIs)
• Secure authentication & transaction systems
• Clean, scalable backend architecture

I focus on building systems that work in production — not just demos.

If you need a developer who understands both user experience and backend logic, I’m ready to help.
