Top Rated

Project details
You will get a fully secure, reliable, and scalable API or payment gateway integration built specifically for your SaaS, CRM, or marketplace platform. Whether you need a custom REST API, a third-party integration, or a complete payment flow, I deliver clean architecture, robust authentication, and error-proof communication between systems.
With experience integrating Stripe, PayPal, Razorpay, Square, Shopify APIs, custom CRMs, and internal systems, I ensure every endpoint is optimized, documented, and production-ready. My development approach includes planning, architecture, integration, testing, and deployment, giving you a complete, end-to-end solution without complexity.
Every API or payment gateway is tailored to your business logic, security requirements, and scalability needs. You’ll receive clean code, clear documentation, and a reliable integration built to support future growth.

Audit project
Farah did a very thorough and thoughtful audit of our MVP. She went beyond surface-level UI comments and really dug into the underlying architecture, AI evaluation logic, and the limitations of the toolchain we were using.
What I particularly appreciated is that she was honest about constraints and trade-offs instead of overselling quick fixes. Her feedback helped clarify where issues were caused by our implementation versus where they were structural to the platform itself, which was extremely valuable for decision-making.
Communication was clear, structured, and professional throughout. I would definitely recommend Farah for audits, AI-heavy MVPs, and early-stage product hardening, and I’d be happy to work with her again in future phases.
