#201: Transforming military discipline into Python skills with PDI
Christina Lang’s journey from nearly two decades in the military to becoming a DevOps architect shows how discipline, persistence, and a growth mindset can drive career transitions. She shares how the Pybites PDI course helped her rapidly level up her Python skills, the importance of being “humble but hungry” when learning, and how mentorship and structured practice make tackling new challenges achievable. Christina also discusses the unique hurdles veterans face when moving into civilian tech, from cultural adjustments to communication styles, and how their dedication and resilience make them valuable team members once they adapt.Today, Christina applies Python to networking automation, building modules for specific tasks and exploring cloud deployments with OpenTofu, AWS, and Kubernetes. For anyone hesitating to take the next step in Python, Christina encourages: “If you don’t feel ready… you probably are. Just pull the trigger, just do it.”Christina's LinkedIn: https://www.linkedin.com/in/christina-lang25Pybites Developer Initialization Program for Veterans: https://pybit.es/veterans/Pybites Podcast 118 - Veterans in the workplace, challenges and tipshttps://www.youtube.com/watch?v=Swg0hj6BPJE ___If you found this podcast helpful, please consider following us!Start Here with Pybites: https://pybit.esDeveloper Mindset Newsletter: https://pybit.es/newsletter 💡Pybites Books: https://pybitesbooks.com/Bob LinkedIn: https://www.linkedin.com/in/bbelderbos/Julian LinkedIn: https://www.linkedin.com/in/juliansequeira/Twitter: https://x.com/pybitesApple Podcasts: https://podcasts.apple.com/us/podcast/pybites-podcast/id1545551340Spotify: https://open.spotify.com/show/1sJnriPKKVgPIX7UU9PIN1

#193: Why coding alone sucks!
In this episode, we share our own experiences of what it’s like to code in isolation — and why it held us back more than we realised at the time. When you're working solo, it’s easy to miss out on learning opportunities, fall into unhelpful habits, or lose momentum altogether.But when you start coding alongside others, everything shifts. We talk about how code reviews gave us instant feedback, how collaborating with other devs helped us level up faster, and how the simple act of being part of a team made coding more enjoyable — and a lot less lonely.Whether you're freelancing, working remotely, or just feeling a bit disconnected, we share some practical ways to break out of that bubble. We also talk about how the PyBytes community has grown to nearly 1,400 developers, all sharing ideas, swapping feedback, landing jobs, and building real connections.If you’ve been feeling stuck or isolated in your coding journey, this episode might be the nudge you need. Because trust us — once you stop coding alone, everything changes.Join our Circle Community today! https://pybites.circle.so/c/start-here___Books mentioned:Reinventing The Store: https://pybitesbooks.com/books/lFI3EQAAQBAJMagician's End: https://pybitesbooks.com/books/nKHPc2SQqScC___💡🧑💻Level up your Python skills in just 6 weeks with our hands-on, mentor-led cohort program.
