πŸš€ About Me

I build things that break, then fix them until they don't β€” that's how I actually learned to code.

I'm a full-stack developer working across the MERN stack and Next.js, happiest in the parts most people skip: the API that has to survive a payment failing halfway through, the auth flow that has to work on a browser I've never tested on, the bug that only shows up in production.

I build for small teams and early-stage products that need one person to take a feature from "wouldn't it be good if" all the way to live β€” interface, API, database, auth, deployment. I also practise DSA regularly in C++, which has changed how I start a problem: less typing first, more figuring out the right approach before I commit to it.

Right now I'm looking for a full-stack or backend role where I can work on real products alongside more experienced engineers.

January 10, 2025 – February 25, 2025

  • Architected 5+ responsive, cross-browser web components with HTML5, CSS3, and JavaScript, reducing layout render times by ~15%.
  • Built and shipped 12 responsive web pages using React, JavaScript, HTML, and CSS, verified across 4 browsers and 3 screen sizes.
  • Reduced page load time from 4.2s to 1.8s by compressing images, lazy-loading offscreen content, and removing unused CSS.
  • Built 8 reusable React components used across 5 pages, cutting build time for each new page.
  • Resolved 30+ UI bugs raised in QA and code review, and worked with a 4-person dev team through review and testing cycle.
