Open-source contribution
As founding engineer I designed and developed more then 50% of the code for a powerful tool for developing microservices in Python. The syntax of the Panini framework is similar to popular web frameworks such as Flask, Aiohttp, and FastAPI, and it provides several convenient features for tackling common challenges when dealing with messaging microservices and other components.
