About Me
I believe the best way to learn is by building real things.
I'm Sagnik Bhattacharya — founder of Coding Liquids, top-rated Udemy instructor, and tech consultant based in Kolkata, India. I started Coding Liquids in 2018 with a simple idea: programming education should be hands-on, project-driven, and grounded in industry standards.
My Flutter course on Udemy has reached over 30,000 students across 174 countries, and has been recognized as one of the best Flutter courses online. I've also consulted for companies like Tata Digital, helping teams build and ship production-grade Flutter applications.
I focus on the what, why, and how — because understanding the reasoning behind the code matters just as much as writing it. Whether it's Flutter, Dart, Python, or Excel with AI, every course I create is packed with real-world projects and ninja challenges.
