Our client was facing serious scalability and customization limits with Shopify. We rebuilt their entire e-commerce system from the ground up using Strapi CMS and Next.js to achieve full control, flexibility, and SEO performance. The result is a fully dynamic, multilingual platform where the client can manage products, content, and promotions independently—no third-party plugin dependencies or commissions. The new tech stack combines Next.js for speed and SEO, Strapi for modular content control, and Stripe for secure payments. We also integrated Apple and Google login, enhancing user convenience and trust. The entire architecture is optimized for high performance, allowing the site to scale seamlessly as the business grows. Key Highlights: - Migrated from Shopify to a self-hosted, scalable architecture (Strapi + Next.js) - Added multi-language support for global reach - Implemented Stripe payments with Apple and Google login - Optimized codebase for speed and SEO performance - E

This project involved building a custom AI mental health assistant trained exclusively on data curated by doctors and wellness experts. The AI is designed to guide users through yoga, meditation, and breathing exercises, offering personalized support for emotional balance and stress relief. The system was developed with a Node.js backend, PostgreSQL database, and a Flutter app for Android and iOS, ensuring a smooth and consistent experience across devices. We implemented HIPAA compliance to protect user data and privacy, and introduced a modern OTP-based login for quick, secure access. Users can chat or speak directly with the AI, receive intelligent, voice-based responses, and benefit from context-aware conversations that adapt over time based on their preferences and behavior. The AI continuously learns from each interaction, delivering more personalized wellness recommendations with every session.

Enhance AI App Features • ₹7,000 INR

We worked with this team for AI product enhancement and new feature development, and it’s been a great experience. They’re not just good developers but real problem-solvers. The team took time to understand our product, even ran user surveys to shape new ideas, and delivered everything on time with proper testing and documentation. Each feature came well-tested with a clear testing plan. Highly recommend them for anyone looking for a dependable development partner.

AI-Powered Blog Content Generator Web App • ₹1,050 INR

Working with Joshi S. was a smooth and professional experience. He delivered a clean, responsive UI with Next.js and Tailwind, and integrated the OpenAI API flawlessly for real-time content generation. His full-stack skills, clear communication, and problem-solving mindset made the project a success. I’d highly recommend him for any AI-powered or content-driven web app development.
