About Hafiz Usman

I help startups build and create fully functional web applications and high-performance platforms in under first 2 weeks. As an experienced fullstack developer and system architect, I provide a comprehensive approach to web design, bridging the gap between "just a coder" and a Product Partner. By leveraging an AI workflow, I create high-quality, scalable systems in 1/3 the time of traditional web development—without sacrificing code integrity.

🛠 Technical Expertise & Tech Stack:

I build modern, scalable web applications using a range of frontend and backend technologies. My expertise spans React, Next.js, Vue.js, Tailwind CSS, and Figma-to-code for clean, interactive UIs; Node.js, JavaScript, TypeScript, Python, and PHP for robust backends; and AI tools like OpenAI API, LangChain, and vector databases for intelligent automation.

My experience also includes cloud infrastructure and DevOps (AWS, Azure, Docker, CI/CD), databases (PostgreSQL, MongoDB, MySQL, DynamoDB), and CMS/E-commerce platforms such as Shopify, WordPress, and WooCommerce.

Beyond core engineering, I provide specialized solutions ranging from high-converting landing page design to complete website design overhauls. As a developer with the eye of a uiux designer, I bridge the gap between aesthetics and performance. I focus on delivering a fully functional user experience, with api integration, with extreme attention detail, ensuring that every landing page or shopify store I develop is not only beautiful but optimized for conversion. Whether you are seeking experienced help for a social media integrated platform or a complex google sheets automation, I ensure the final site meets the highest industry best practices.
