Client Reviews

Here is what clients and team leads have to say about collaborating with me on production applications.

“Honestly, Ayush was a lifesaver for our Next.js project. We had a super tight deadline and a limited budget, but he got the entire web app up and running ahead of schedule. The code is super clean, and he even helped us set up some basic SEO things that really boosted our search traffic. Definitely hiring him again!”

Sarah Jenkins

“I've worked with a lot of developers, but Ayush stands out. He built our React Native app using Expo and NativeWind, and the UI is incredibly smooth. What I appreciated most was how he kept us in the loop the entire time and didn't charge us agency-level fees. Really solid work.”

David Chen

“We needed to optimize our MongoDB database and NestJS backend because things were lagging. Ayush jumped in, sorted out the query issues, and now everything runs incredibly fast. He's fast, knows his stuff, and didn't cost a fortune. Strongly recommend!”

Elena Rostova

“Ayush built a really clean e-commerce site for us. I was worried about the payment integration and Stripe checkout, but he handled everything perfectly. He delivered exactly what we wanted on time, and his pricing was very fair. Super happy with the final product.”

Amit Sharma

“Really happy with the mobile app Ayush built for us! It's super fast, and the animations are exactly what we had in mind. He suggested some great UX tweaks that made the app way better to use. He's very professional and finished everything right on budget.”

Sneha Reddy

“Our store's loading speed was terrible and we were losing customers. Ayush did a complete audit, optimized the custom theme, and fixed our SEO. The site loads instantly now and our conversion rate went up. Saved us a ton of cash!”

Rohan Malhotra

“Absolutely amazing frontend work. He turned our Figma designs into a working Next.js site, and it looks identical. The hover effects and transitions are very clean. Great communication, fast turnaround, and very reasonable pricing.”

Carlos Mendez

“He upgraded our Expo app to the latest version and resolved some really tricky navigation bugs. The app is much more stable now. Ayush is incredibly skilled and got it done very quickly. Great experience working with him!”

Deepika Verma

“We wanted a custom dashboard with real-time updates for our feedback tool, and Ayush built it using Socket.IO. The sync works perfectly. He's super smart, easy to talk to, and delivered exactly what we needed without any hassle.”

Rajesh Patel

“Highly recommend Ayush for full stack work. He optimized our site's SEO, fixed our page speed issues, and cleaned up our backend. The project was completed on time, and he went above and beyond to make sure everything was perfect.”
