Happy Deswal

I'm a Computer Science Engineering student (GPA 9.01/10) with hands-on experience delivering production-ready Android apps and modern web solutions. I don't just write code — I build things that are clean, scalable, and genuinely useful.
On the mobile side, I develop native Android applications in Kotlin and Java using MVVM architecture, with Room for local storage, Retrofit for API integration, and Coroutines for smooth async performance. I've worked with AI providers like Gemini and Groq to bring intelligent features into mobile apps, and I follow Material Design 3 principles to ensure the UI feels polished and intuitive.
On the web side, I work across the full stack — building responsive frontends with HTML, CSS, JavaScript, and React, and powering them with backends in Node.js/Express or Flask. I'm comfortable designing REST APIs, connecting databases (MySQL, MongoDB, SQLite), and deploying applications to cloud platforms like Render and Firebase.
One of my flagship projects is Finn, an AI-powered personal finance Android app I built end-to-end — featuring an AI chatbot, live market news, currency-aware personalization, investment tracking, and CSV/PDF export, all backed by a Node.js REST API. I've also built NexaBank, a bank-styled web platform integrating a Flask ML backend serving a real loan approval prediction model.
My tech stack spans Kotlin, Java, JavaScript, Python, React, Node.js, Express, Flask, Room, Retrofit, Firebase, and Git. Whether your project is a mobile app, a web platform, a REST API, or needs AI features woven in — I can handle it from design to deployment.
I'm deadline-driven, communication-first, and honest about scope. If I can build it, I'll deliver it right. If something is beyond my range, I'll tell you upfront.
Open to: Android app development, full-stack web projects, REST API design, AI feature integration, and frontend UI implementation.
