Portfolio

Frontend Developer - Barnebys
Frontend Developer - Barnebys

Barnebys is the world’s leading search service for vintage design, art, antiques and collectibles. It comes with an extensive database (free) of auction results and a top of the line valuation service. Built PHP bots to crawl through auction websites and added info to Barnebys' database. Developed bots for a number of auctions that were poorly executed/crawled in previous auctions.

Lead Developer - Drag n’ Drop Calendar
Lead Developer - Drag n’ Drop Calendar

Developed a Drag n’ Drop calendar (could not use external library) to schedule walks between many days, times and walkers. It was well-optimized for rendering, as it allowed users to color the right time, region, and appointments when dragged on, and also showed what time the appointment was being dragged over. This process produced a lot of intensive rendering of some components and some unwanted rendering of others. This meant extensive optimization of the rendering of every element using Should Component Update, drag API conditionals, and libraries such as react-visibility-sensor.
