Who I Am

Sanjeev Kumar (Tricky User)

Hi, I'm Sanjeev Kumar — better known online as Tricky User. I'm a passionate Full Stack Developer with over 4 years of hands-on experience designing and shipping web applications and apps end-to-end.

I build apps and websites at the most affordable prices, and I work with both hands-on manual development and modern AI-assisted development to deliver faster without cutting quality.

My work spans from crafting pixel-perfect front-ends to architecting robust back-end systems and APIs. I'm big on performance, clean code, and constantly leveling up with modern tools and practices.

When I'm not coding, I'm creating dev content and sharing what I learn with the community across YouTube and Telegram.
