Hey there, I'm Sebin P Johnson β a self-taught engineer turned Engineering Manager with 9+ years of experience across the full software landscape. I've built WhatsApp bots before the APIs existed, shipped mobile apps to half a million users, migrated enterprise databases with zero downtime, and now lead AI product engineering at Magnit Global. I'm a generalist at heart: I'll pick up whatever language, framework, or paradigm the problem demands and ship something that works. My real obsession is keeping up with where software is going β especially AI β and finding ways to put it to use before it becomes mainstream.
