A company that offers SAAS products and API integrations for the Mortgage industry.

• His main activity, which took several months, in the company was to work on a new feature/project to reduce the amount of processing time in a process that demanded a ton of data to send and receive. Clients used to hit a single endpoint a hundred (or even more) times in a row to get results for several scenarios. Matheus' job was to develop, with another team, a feature to process all those scenarios at once, in batches. Using async tasks handled by Celery, the initial result, before wide release, was a contract that helped to reach USD 10mi ARR for the company.
• Proposed the use of OpenAPI to document our API.
• Led a project that the outcome, before wide release, was a contract that helped to reach USD 10mi ARR milestone for the company.
• Helped document almost half of endpoints.
