Core Technologies: • Flutter for iOS & Android • React.js & Next.js • Laravel & Node.js • MySQL, PostgreSQL & MongoDB • Firebase & Supabase • REST APIs & third-party integrations What I Build: • SaaS & subscription platforms • Custom business software • Mobile applications • Web applications & dashboards • Marketplaces & booking platforms • E-commerce systems • Admin panels & management systems • AI-powered features & automation I also work with integrations such as Stripe, PayPal, maps, authentication, push notifications, real-time communication, and other third-party APIs. My focus is not just writing code. I first understand the business requirements, then build a solution that is practical, scalable, and maintainable. Many of my clients continue working with me after the initial project for new phases, improvements, maintenance, and additional products. Have a specification, Figma design, MVP idea, or an existing product that needs improvement? Send me the details and I’ll review the best way to build it.

I designed and developed a minimalistic, intuitive mobile app called MyPetPal, focused on simplifying pet vaccination management for pet owners. The app allows users to effortlessly schedule, track, and receive reminders for their pets’ vet appointments and vaccinations. The design features a vibrant, friendly interface with soft colors, playful illustrations, and clean navigation. The experience starts with a warm onboarding screen and transitions into a smart reminder dashboard where users can view upcoming appointments and easily add new ones. The visual identity is pet-friendly and modern, designed to feel trustworthy and caring.

Happy Bible is a mobile application developed to help users engage with the Word of God through a clean, user-friendly interface. I designed and developed this app to serve as a daily companion for Bible reading, meditation, and scripture memorization. It includes features like verse of the day, offline access, multiple Bible translations, bookmark and highlight tools, a journaling section, and a prayer tracker.

What makes Happy Bible special is its thoughtful design tailored specifically for believers seeking a deeper spiritual journey. The app is lightweight, distraction-free, and crafted with a focus on clarity and usability allowing users to focus on Scripture without unnecessary clutter.

Social Media UI/UX Enhancement

Hammad is a talented UI/UX designer who took the time to understand our platform and produced thoughtful, modern Figma concepts based on our vision. He communicated well, was receptive to feedback, and remained available for revisions. Although we ultimately placed the project on hold due to circumstances on our side, he handled the closure professionally and fairly. I was satisfied with the work he completed and would gladly consider working with him again in the future.

Working with him was great. I can not believe what a wonderful job he did on my website and store. There was great communication, and the work is simply outstanding, more than I ever expected. I gave him a lot of different things I wanted, and we worked together to build the bookstore the way I wanted and even better, as his own design was better than I was thinking of. I have already set up a new project with Hammadhassan21. He will have all my work from here out. Hammadhassan21 excelled!
