Julian Sequeira
Co-Host of Teaching Python
Julian Sequeira is a Python coach, mindset coach, and technologist based in Australia who joins Teaching Python as a co-host bringing a fresh perspective from outside the traditional classroom.
Julian's coding journey started with C++ in high school, wound through HTML, CSS, and JavaScript, and took a decisive turn toward Python in 2015. Since then, he's been hooked — building tools to solve everyday problems and discovering that Python's real power is helping people who don't even realize code can fix what's frustrating them.
Professionally, Julian spent years as a Data Centre Technician at Amazon Web Services keeping the cloud running, and co-founded the PyBites Python community where he's coached hundreds of developers. Throughout his career, he's had a knack for mentoring and training — from launching an internship program in the AWS data centers to one-on-one Python and mindset coaching.
On Teaching Python, Julian brings the perspective of someone who coaches adults and professionals rather than K-12 students, creating a natural complement to Sean and Kelly's classroom experience. He's here to provide insights from his corner of the world, bridge the gap between learning to code and applying it professionally — and maybe provide some comic relief along the way.

Episode 158: Will Vincent on Django, AI Coding, and Why Fundamentals Still Matter
June 10th, 2026 | 1 hr 12 mins
In this episode, Python Developer Advocate and author Will Vincent joins the show to talk about why Django's "batteries-included" approach and security-focused design still matter, especially as AI-generated code becomes more common. The conversation explores the challenges new developers face when learning to program, the growing disconnect between quickly building a prototype and creating software that can survive in production, and the realities behind so-called "vibe coding." Along the way, Will shares his perspective on why experience, trust, and core software engineering practices continue to matter, even as open-source communities grapple with a flood of AI-generated content.

Episode 156: When Code Leaves the Screen
May 23rd, 2026 | 56 mins 2 secs
In this episode of Teaching Python, Kelly Schuster-Paredes and Julian Sequeira talk with engineer and maker Todd Kurt about physical computing and what happens when code moves from the screen to hardware. The conversation focuses on CircuitPython and MicroPython, including how they differ in design, teaching focus, and tradeoffs.
Todd describes his background in engineering, web development, and open source hardware, and the group discusses practical classroom challenges such as bootloaders, UF2 files, board compatibility, libraries, and wiring mistakes. Kelly and Julian also share examples from their classrooms, where students use boards, sensors, NeoPixels, and other devices to build tangible projects and develop troubleshooting skills. -
