AI Management Tool for Healthcare
Hassan delivered this project with exceptional clarity, technical skill, and professionalism from start to finish. He quickly understood the requirements for a secure AI healthcare management tool and translated them into a practical, well-structured solution without unnecessary complexity.
His communication was consistent, clear, and proactive. He met timelines, shared updates regularly, and handled every detail with care especially around data sensitivity, system architecture, and usability for medical staff.
What stood out most was his ability to combine strong backend architecture, database expertise, and AI integration into a clean, easy-to-use platform. He remained cooperative, responsive, and solution-focused throughout the collaboration.
I highly recommend Hassan to anyone looking for a dependable developer who truly understands how to build secure, intelligent, and scalable systems. Would gladly work with him again.

Medical imaging with ai
My experience with TECHOBIX was the best possible. Raja and it´s equipment were available al almost anytime, despite a 10 hour difference between our locations. The attention and meetings we had was excellent since the begining. I had written documentation at the end of our project and a final meeting where all of the project was explained. Plus they are open to questions even after the ending of contract.
The deadline were met on time and other than that I can only say that I recomend these guys 100%

⭐ Top Rated Full Stack Shopify Developer
✅ 5+ Years of Production Experience
✅ End-to-End Product Ownership
I am a Full-Stack Shopify Developer specializing in building high-converting stores, custom Shopify Apps, and AI-powered automation workflows that scale your e-commerce business. Because I come from a heavy MERN-stack and AI background, I don't just build pretty storefronts. I engineer robust backend systems, custom APIs, and seamless integrations.
Here is how I can help grow your store:
🛍️ Custom Shopify App Development
Need unique features that public apps don't offer? I build secure, embedded Shopify Apps using React, Node.js, Remix, and GraphQL that integrate perfectly with your store's ecosystem.
🎨 High-Converting Theme Customization & Liquid
Whether modifying an existing OS 2.0 theme or building custom sections from scratch, I write clean, optimized Liquid code to ensure rapid loading speeds and perfect mobile responsiveness.
🤖 AI & n8n E-commerce Automation
Save 10+ hours a week. I integrate custom AI workflows (Claude/OpenAI) to automate product description generation, customer support, and inventory tracking, connecting your tech stack flawlessly via n8n.
🌟 My Technical Stack for Shopify:
• Frontend: Liquid, React.js, Next.js, Tailwind CSS
• Backend: Node.js, Express.js, GraphQL, REST APIs
• Automations: n8n, OpenAI API, Claude API
