About Me

The dev behind the code.

Hi, I'm Piyush Arya — a freelance full-stack & app developer in Delhi, India with 2+ years of hands-on experience building websites, web apps, and mobile applications that real businesses use every day.

I specialise in PHP, MySQL, Bootstrap, JavaScript, Flutter, and Firebase, along with third-party integrations like Razorpay, Cashfree, and REST APIs. I write clean, maintainable code across web and mobile — and I ship on time.

I care about three things: performance, clean UI, and happy clients. Whether you need a simple landing page, a full SaaS dashboard, or a cross-platform mobile app — I've built all three.

Currently open to freelance projects across India and globally. Let's build something great together.

⚡
Fast Delivery
I work in focused sprints and always hit the deadline — no excuses.
🧹
Clean Code
Readable, maintainable, well-structured — easy to scale or hand off.
📱
Mobile-First
Every web project is fully responsive — and when you need a real mobile app, I build that too, with Flutter.
🔒
Secure & Reliable
Validated inputs, secure payments, and robust backend logic on every build.
