Full-stack developer • BI engineer • Data workflows

This website started as a personal learning project — a space where I could experiment, build things in public, and document what I learn along the way. The earliest version was built on the MERN stack where I taught myself component architecture, authentication, deployment workflows, and version control.

Over time, the site evolved. I introduced a cloud-backed WIP section where I share in-progress ideas, prototypes, algorithm experiments, and workflow improvements. Today, the site is rebuilt with Next.js and Tailwind CSS, with a hosted backend and secure login — designed to grow with whatever I choose to work on next.

I’ve always been drawn to building practical systems. Not theoretical exercises, but real tools that automate work, extract meaning from data, or simply make life easier. I enjoy understanding how things work end-to-end — from database schema to UI polish — and refining workflows until they feel smooth and intuitive.
