Experience
Image Optimization for Toptal's Website
https://www.toptal.comTailored Cloudflare Workers that handle all Toptal's website images. A worker was responsible for optimizing and formatting the images into web-friendly formats like AVIF or WebP, reducing the overall size of all files. An image component built using React was integrated to use the worker's URL to handle all the images used throughout all the pages, leading to a reduction in bundle size by more than 80%. One of the main challenges of this tenure was working with the homepage because it demanded meticulous attention to detail as the company's front door.
Toptal Resume Pages
This project involved redesigning the resume pages for the Toptal website. As a senior front-end engineer, I worked on applying design mocks as a base for the new resume pages. I created new components used by the pages as portfolio modals, collapsible section content, and sticky profile photos on the page.

I spearheaded the development of a dynamic client portal aimed at simplifying the job posting journey and expediting candidate discovery. The project prioritized user-friendly interfaces and seamless functionality, resulting in an intuitive platform where clients can effortlessly post new job listings and swiftly search for candidates with specific skill sets. Leveraging the latest technology and responsive design, the client portal empowers businesses like never before, facilitating seamless connections with top talent and optimizing the recruitment process for unparalleled success.
