Über Mubashir Ahmed
I am a highly skilled and experienced Full Stack .NET Developer with over 10 years of hands-on experience building high-performance enterprise applications, e-commerce platforms, and scalable backend systems. I specialize in ASP.NET Core, C#, React, Flutter, Python, and modern cloud-native architectures.
Throughout my career, I’ve helped businesses transform ideas into powerful digital solutions, from designing secure APIs and microservices to developing fast, user-friendly web and mobile apps. I focus on writing clean, optimized, and maintainable code that stands the test of time.
I have worked with startups, SMEs, and large enterprises across multiple industries, delivering projects such as:
- Enterprise ERP modules
- High-transaction e-commerce systems
- API integrations (WhatsApp, Payment Gateways, SMS, Third-Party CRMs, Sage, Odoo, etc.)
- Cross-platform mobile apps
- Automation tools and backend services
- Secure .NET Core APIs with JWT authentication and role-based access
- Ride-sharing backend with seat booking, fare calculation, and promo code system
- Home-services app backend with booking, scheduling, and driver assignment
- Custom modules: cheque management, rental equipment, provident fund, AML workflows
- Face-recognition attendance backend with real-time logs
- Tablet-based POS backend with syncing engine
- Digital document signing system
- Messaging backend for chats, groups, and media
- GPS tracking and auto check-in/check-out backend
- Video platform backend with uploads and streaming
My goal is simple: to turn your ideas into reality with world-class execution, transparent communication, and on-time delivery.
If you’re looking for someone reliable, fast-learning, creative, and committed to quality — I’m here to help you build something exceptional.
Let’s work together and take your project to the next level.
