Hi, I'm Sundram Gupta 👋

Software Developer • App Developer • Builder • Open-Source Enthusiast

I build mobile applications, developer tools, interactive learning platforms, and real-world software products.

Currently pursuing BCA at Shri Ramswaroop Memorial University, while turning ideas into shipped products.

I'm Sundram Gupta, a BCA student and software developer focused on building useful products rather than just demos.

My current interests revolve around:

• 📱 Flutter & cross-platform application development
• 🌐 Web applications and modern frontend systems
• 🧠 Computer Science visualizations and developer tools
• 🗄️ Offline-first and local-first software
• 🤖 AI-powered applications
• ⚡ Hackathons, open source & rapid product development
• 🏗️ Clean Architecture, scalable codebases and thoughtful UX

I enjoy taking an idea from:

Problem → Architecture → Interface → Implementation → Deployment

Some principles I actively follow:

• Feature-first architecture
• Clean separation of concerns
• Reusable components
• Offline-first where appropriate
• Minimal unnecessary dependencies
• Responsive interfaces
• Accessible UX
• Meaningful Git history
• Documentation that developers can actually use

Product engineering

I'm particularly interested in the space between software engineering and product design — building software that is technically solid while still being something people actually want to use.

I enjoy building in public and experimenting with ideas that can help other developers and students.

Most of my public work lives here:

github.com/sundramdotdev

If something I build is useful to you, feel free to ⭐ the repository or open an issue.

I'm always interested in:

• Open-source collaboration
• Hackathons
• Interesting software ideas
• App development
• Developer communities
• Building useful products
