Senior FastAPI Engineer

Now we are looking for a Senior FastAPI Engineer to join our backend development team. This role involves designing, building, and maintaining high-performance APIs and backend services using FastAPI.


Project description

Our project involves upgrading a Python application from version 2.7 to the latest 3.x release while also enhancing its overall performance. This application originally was developed for analysts. Its primary function is to gather data from various websites and store this information in the database. Subsequently, analysts can perform diverse operations through regular expressions (regex) and conduct comparisons against known vulnerabilities.

Initially, this tool was designed for internal use. However, due to its remarkable utility, our customer has decided to transition it into a production-ready version.
