Top SchoolJacek Ostanski is a seasoned Python engineer and founder with 14 years of experience building web applications, leading small SCRUM teams, and transitioning into DevOps and AWS infrastructure automation. He runs PyMasters, a thriving community and training program for Python developers, and authored a beginner-focused eBook to help novices ship real projects.
