About
Hey,
Iβm Karthikeyan π, a Senior Software Engineer who spends most of my time writing JavaScript, fixing bugs (mostly the ones I created π ), and figuring out why CSS does what it does. Iβve been in the industry for 7+ years, working primarily with React, TypeScript, and performance optimization.
This is where I share my thoughts on frontend development, web performance, and everything in between. Expect posts on:
JavaScript & React β tips, tricks, and lessons learned the hard way
Debugging nightmares β because weβve all been there π
System design & DSA β preparing for Big Tech interviews, one problem at a time
Tech career insights β things I wish I knew earlier
Improving my DSA and system design skills
Writing more about tech and my learnings
Gym and running, because sitting all day isnβt ideal
Big One Piece fan (Zoro all the way π΄ββ οΈ)
Wouldnβt mind owning a Koenigsegg someday
I write about things I learn, break, and sometimes fix. Stick around if that sounds interesting! π
