Experience
Workout Planner
A workout planner using React lets users develop their exercise plan and suggests exercises for different muscle groups. The suggestions also account for the available equipment with the user and recommend the most relevant YouTube videos for the same exercise. Users can also look for specific exercises or exercises related to a particular body part.
Cryptocurrency News App
A web app for monitoring news related to the most popular cryptocurrencies. The portal shows the latest price, the volume traded, and the most recent fluctuations for the top 10 cryptocurrencies. The user can edit this list to show other cryptos as well. Users can search for content related to specific coins and determine catalysts. The app was created using React and RapidAPI for data.
Unified Uploads
https://help.aconex.com/DisplayContent/add-documentsAn AngularJS-based tool to upload and record metadata for multiple documents (5000 max limit).
The unified uploads form captures details like the name, version, approved date, author, etc., where each field is custom validated in real-time. Each document also has its status badge that allows the user to see if it is ready to be registered or missing some key information. The tool can handle files of sizes up to 100GBs.

Web-based Portfolio
I developed a Gatsby and React-based portfolio for a designer. I used Gatsby because the client wanted to implement SEO in the future. The website had a landing page, an about page, and a section where the user could showcase his projects. All the data related to projects and the about page was fed through markdown files, making maintenance extremely easy. I used GraphQL plugins to extract text from MD files and add images and used StaticQuery and data to generate reusable components.
