Working with Prateek on our Bitwarden client application was an excellent experience. They demonstrated deep technical knowledge of Bitwarden’s open-source stack and delivered a fully customized, secure, and reliable client application across platforms. The project involved advanced encryption handling, performance optimization, and seamless integration with external services, all of which were implemented flawlessly. Communication was clear and consistent throughout, and they provided detailed documentation for deployment and maintenance. We are very satisfied with the final product and look forward to working with them again on future enhancements

Prateek successfully delivered our CRM SaaS project from start to finish. They implemented all the requirements exactly as documented — authentication, client management, reminder automation, dashboard, and admin panel. The code quality was excellent, deployment to AWS/Vercel was smooth, and communication throughout the project was outstanding. I’m very satisfied with the final product and would gladly work with them again.

You will get 🤖 Agentic AI: Knowledge & Workflow Automation
Prateek Rastogi built an amazing Grocery Store Agent that completely streamlines my shopping workflow. The agent automatically extracts my grocery list from Google Keep, searches for the items on Morrisons’ website, and even handles alternatives when products are unavailable. It then adds everything to the cart and provides a clear summary with the total price.
The implementation was smooth, reliable, and thoughtfully designed. This guy ensured the integration between Google Keep and Morrisons worked seamlessly and paid close attention to user experience details. Communication was excellent throughout the project, and delivery was right on time. This solution saves me time and effort every week.
I’d highly recommend Prateek for anyone looking for intelligent automation and practical AI solutions.
