Build Scalable Backend for a French Exam Prep SaaS (Supabase + GPT + Stripe)
Working with Karun and his team on the backend of my French exam prep SaaS was a great experience. The project involved building a scalable and reliable system using Supabase, GPT-based logic, and Stripe, and they handled the complexity very well.
They worked hard to bring the platform fully live, were responsive throughout the process, and took the time to understand the product logic rather than just implementing features blindly. The backend is solid, well-structured, and supports a real production use case, not just a prototype.
What I appreciated most was the team’s commitment to getting things right and pushing through challenges to deliver a finished, polished product. The website is now live, functional, and looks great.
I would recommend Karun and his team to anyone building a serious SaaS product that requires a thoughtful backend, integrations, and long-term scalability, and I would be happy to work with them again.

React Expert Needed to Build Modern SaaS Frontend for Premium TCF Canada
Karun did an excellent job on our React and UI/UX frontend work for a modern SaaS product. He was reliable, detail-oriented, and very comfortable working with a real production setup rather than a simple demo.
He understood the product goals clearly, translated designs into clean and responsive React components, and was thoughtful about UX decisions, spacing, and edge cases. Communication was clear throughout the project, and he was open to feedback and quick to iterate when adjustments were needed.
What I especially appreciated was his ability to think beyond just “making it work” and instead focus on building something polished, consistent, and user-friendly.
I would confidently work with him again on future frontend or React-based projects and recommend him to anyone building a serious SaaS product.
