At Smart Business, I developed an OKR module and built the Tasks page end-to-end for an HCM and LMS product. I also integrated real-time updates and backend APIs for a pricing-intelligence portal.

For HR analytics, I was the sole front-end developer and built seven custom Power BI visuals, with interactive features including cross-filtering and drill-through. I also designed a monorepo architecture with a shared component library.

As a freelance web developer, I built and published websites for local businesses. I also built and sold two additional branches of Startek English Language School, which served around 200 students annually.
