• Led the consumable notes project, an event-based invoicing system that allows the subcontractors to generate the invoices for the consumables that have been used.• Designed the database schema and was responsible for populating the database from various sources like events and clients from various services.• Created the consumables API that shows the total price, the amount of consumables used, and whether an invoice can be generated for a given date.• Created consumable details API that shows the breakup of every consumable used, with dynamic filters to filter out the results based on consumables.• Created the consumables history API which would get all the invoices generated.• Used multithreading in the APIs to reduce the latency by a significant amount.• Created the user interface for the partner portal for consumable note project. The interface included multiple tables to show the breakup, total price, and the history of the invoices generated. • Was also a part of a "service note" project where I created a read copy of contract condition data and wrote an initial data import policy for the same in the subcontractor invoicing service.• I have also contributed to migrating most of the pages in the turnaround portal to the latest React version using the Lynx component library.

• During my internship, my primary focus revolved around migrating a B2B web application called Turnaround Portal to the latest React version, involving the creation of the entire user interface from scratch. I played a key role in the comprehensive UI development of some features. Also, I integrated stream API for notifications in the turnaround portal.
