Zibtek - Full-Time

Bengaluru, Karnataka, India
I dove headfirst into the startup grind, showing major hustle on a bunch of projects both our own stuff and client work. This gave me a crazy diverse skillset and leveled up my problem-solving game. I was all about collaborating with different teams, contributing to and learning from Agile/Scrum. Basically, I was a project lead pro, flexing my project management skills. On top of that, I was designing architecture, doing code reviews, and building hybrid microservices using cloud tools. This meant I was tight with the DevOps team, sometimes even building, debugging, and fixing code live in production. Startup life could be intense, and mentorship wasn't always a thing, but that just made me a master of DIY learning—heavy on the research, docs, and trial and error, which seriously boosted my self-reliance.

Mumbai, Maharastra, India
This was a total career twist. It had that full-on coding bootcamp vibe – fast-paced and jam-packed with hands-on projects that seriously leveled up my dev game. I was deep-diving into code, sharpening my logic, and getting hands-on with basic data structures using Java and TypeScript. I even built some cool stuff, like chat and note-taking apps, using JavaScript, Node.js, AngularJS, Core Java, and the MERN stack. I also got my hands dirty installing libraries, testing out new tools, and integrating third-party APIs like Stripe and Twilio, super fun stuff. The mentorship, with a focus on teamwork, communication, and getting to the bottom of problems. I was constantly bouncing ideas off tech leads and project managers, hitting up product docs and online resources to cream on solutions. This whole experience was the foundation stone for my journey into full-stack development and modern engineering.
