I build test automation systems by day and indie developer tools by night. Through Code By GK, I share what I learn - tools you can use, courses you can follow, and resources you can ship with.

What I Build
Products, tutorials, and resources
Three ways Code By GK can help you - whether you're looking to use a tool, learn a concept, or ship faster.
Tools that solve real problems
Web apps, Chrome extensions, and CLI utilities built because existing tools didn't cut it. NanoRead, DOM2POM, ZapComment, Dorkmine - each one started as a personal frustration.
Explore ProductsReady-to-use assets
Frameworks, templates, and automation kits you can drop into a real project. Built to save hours, not minutes.
Browse ResourcesNotes from real learning
Structured course notes written while learning - filtered through 11 years of QA engineering experience. Not summaries. Opinionated, hands-on, and built to be used.
