Hey there! I've been in the coding game since 2010, wearing a bunch of different hats. I'm all about that full-stack life! Java and Python? Yup, been there, done that.

I've been in the coding game since 2010, wearing a bunch of different hats. I'm all about that full-stack life! Java and Python? Yup, been there, done that. Funny thing though: with all the Java coding I've done, I still can't get it to make me a cup of coffee. And as for Python, I'm convinced it’s more of a friendly pet than a programming language. I jumped onto the mobile train around 2013, starting with Java and Objective-C. Fast forward to 2017, and I'm diving deep into Kotlin and Swift. Love how they keep things spicy! Speaking of spice, since 2018, I’ve been mixing it up with Flutter and React Native for some cross-platform action. Flutter's cool and all, but I'm still waiting for those real-life butterflies, you know? On the web side of things, I've rolled with PHP, Laravel, and Node.js for the backend vibes, and jazzed up the frontend with some React magic. Sometimes I think Laravel might just start humming a tune with how much I use it. All in all, I'm just a tech enthusiast, looking to create, collaborate, and occasionally crack a joke or two about my coding adventures. Let’s build something awesome together! ??? less
