Rental software platform designed to streamline the management of rental businesses. It offers tools for managing inventory, customers, orders, invoices, payments, and routing, among other things. Also provides functionalities for creating websites and generating proposals to showcase rental products and services.

Responsibilities & achievements

I led a team of over ten developers and played a pivotal role in fostering strong collaborative relationships with the customer service team. I had a central role in the development of both the backend and frontend. I implemented code quality strategies, including unit testing, behavior testing, continuous integration/continuous deployment (CI/CD), and other agile methodologies, which significantly elevated the development process. A major highlight of my contributions was the significant performance optimizations I introduced. Notably, the implementation of 'jemalloc' drastically improved garbage collection efficiency, which boosted the application's speed by an impressive 300%. Furthermore, I spearheaded the integration of monitoring tools such as Datadog. These tools were critical in tracking and overseeing application performance, enabling us to proactively identify and resolve potential issues before they impacted our users, thus maintaining a seamless operational flow.
