Increase Team Productivity

You have more work that needs accomplishing than you can do. You don't want your employees to trip over confusing or obfuscated code while they're trying to get work done.

Let Your Engineers Experiment

You want to strike a balance between maintaining code quality and empowering your engineers push the envelope without feeling beholden to a rigorous template.

Prevent Employee Turnover

Your front-end devs want to become full-stack devs. They're already excited about contributing to your back-end code and it would be handy if they could help out there.

Expert Guidance From an Experienced Python Mentor

Hi, I'm Trey Hunner and I have been a developer for over a decade.

I speak at Python conferences around the world like PyCon US, DjangoCon US, PyCaribbean, and PyCon Australia. I co-organize Python meetups and workshops, and sends weekly Python exercises.

I'm a former director of the Python Software Foundation and a current member of the Django Software Foundation.

While I love writing code, I love teaching Python even more. I can help your developers effectively level-up their programming skills through on-site or remote trainings.

Available Team Training Courses

No Boring Lectures

In my classes, we learn with our hands on the keyboard. I live-code on the projector with the guidance of your team and we’ll take multiple short exercise breaks each hour.

Ongoing Learning Resources

At the end of my training, I leave students with a detailed guide of everything we learned together in class as well as a wealth of bonus material for continued learning.

Clear ROI on Training

Training increases productivity, but it also increases the potential for your team to write code that is less error-prone and more feature rich (you don't know what you don't know).

What People Say About Trey's Training...

Carly Litchfield

Senior Engineering Manager at Galileo

Our team was seeking training to help us migrate from Flask to Django and Django REST Framework.

Justifying the business case to spend money and time on training was the biggest obstacle for us. I was also worried we might hire a trainer who wasn't engaging, like many corporate HR or security trainers. After researching five potential trainers, Trey seemed like the most knowledgeable. Trey also had the most relevant industry experience and he specializes in Django, which was important for us. After my research, I was confident we wanted to work with Trey.

Trey's training was totally worth it! I was surprised at how much our team needed to learn about Django. After the training, our developers seemed much more empowered to jump into our Django codebase. The best part of the training was the interactivity. Writing the code ourselves and opening our own pull requests really seemed to cement the learning.

Trey carefully tailored the training to our organization's needs. He made sure he understood our intentions for using Django and then modified the training sessions to suit our needs. For example, he realized we were mostly using Django as an API for a single-page-app, so he modified the training to cut out Django's templates and focus more heavily on Django REST Framework instead.

Trey had lots of patience for different levels of engagement among the trainees, and he met people where they were. He also accommodated people who had to miss a session or two by sending them summaries and catch-up homework. During the training, I had at least five different individuals give me unsolicited positive feedback about how the training sessions were going.

I would recommend Trey's trainings to teams that are getting started with Python and/or Django. I would also recommend them to companies that hold regular trainings for new hires.

Natasha Fields

Human Resources & Recruiting Manager at Artemis Consulting, Inc

After seeing Trey’s credentials, to include being a speaker at PyCon, I was confident that he was the mentor we needed to bring on for our team. Trey’s offering is justifiable for the level of skill, adaptability, and thoroughness of his course. The employees who attended the training with Trey raved of his skill, his attitude, and mentorship! Also, a huge factor was that Trey accommodated a spur-of-the-moment addition to the curriculum; what more could you ask for when looking for a trainer!?

Trey was prompt, easily accessible, and communicated every aspect of his training beforehand; we knew what to expect. He delivered. In addition to the hands-on training, Trey provided project work (self-study) for the developers to really grasp the concept of Python; that was added value as we hired Trey to get our Java devs prepared for a Python switch.

I would absolutely recommend Trey's training services for both Python and Django! Trey was great! I would hire him again in a heartbeat. I am so kicking myself for not attending the training – for me!

Bob Pappas

Director Apps & UI Engineering at Ayasdi

The biggest obstacle we experienced was our training budget. We had to move out to a future quarter for budgetary reasons. Despite that obstacle, we found this training was very much worth the results.

Trey's pace for each day was appropriately quick. The hands on workshop sections were very valuable. Trey's live coding, rather than viewing slides, was also very effective.

Both the Python and Django sessions gave us very strong foundations in each topic. We really loved the test driven development flavor to the training.

Our training was set up for already experienced developers in Java or JavaScript and I would recommend it for that audience. We really did come away feeling that Trey is an expert at this.

John Coogan

Co-Founder & CTO at Soylent

There weren't really any obstacles that would have prevented me from buying Trey's training. I think my team liked getting to spend a few days in San Diego and the price of the training was reasonable. I was a little bit worried about the relevance, but that's always the case for new training programs. It was absolutely worth doing. Both devs immediately started working much more directly with our full stack and are both now thought of as full-stack engineers in every way.

I really enjoyed building the curriculum with Trey. He never shied away from a broad or open-ended curriculum that would cover a lot of topics.

I would absolutely recommend Trey's Python for JavaScript developers training. It was the most effective class I've seen to date when it comes to bridging the gap between these two languages quickly and with quality. Everyone enjoyed Trey's training. I highly recommend it!

Examples of My Teaching Online

List Comprehensions and Generator Expressions for Data Processing

This is a 3 hour tutorial I taught at PyCon 2018 on some Python-specific looping constructs that are particularly helpful when processing data. The workshop material can be found at

This tutorial, like my training workshops and courses, is exercise-driven and entirely interactive. We spend the entire time either working through exercises individually or mob programming within Python shell or a code editor.

Python Oddities Explained

This is a 25 minute talk I gave at PyCon AU 2019. In this talk we dive into some common (and not so common) gotchas in Python.

This talk was heavily inspired by questions asked by my corporate training students and tweets I've made over the years on the #pythonoddity hashtag.

Lazy Looping: The Next Iteration

This is a 25 minute talk I gave at DjangoCon 2019 on lazy looping with iterators and generators. In this talk we discuss Python's iterator protocol and Python's generator functions and generator expressions. This talk takes a practical look at the power generators, demonstrating how chained generators and iterators allow Pythonistas to break up large for loops into smaller, more descriptive, and more readable sequences of loops.

This talk is not exercise-driven or interactive and is unlike my typical hands-on style of teaching. The way we approach the problem of understanding iteration is quite similar to the way we look at this problem together in my workshops though.

Easier Classes: Python Classes Without All the Cruft

This is a 30 minute talk I gave at DjangoCon US 2018 on some tools that make class creation a bit easier in Python. Some of these tools are built-in to Python and some are third-party, some have been around for a while and some are brand new.

This talk, is unlike my typical hands-on style of teaching but, as is common during in my workshops and tutorials, we do take a look at a number of ways to solve a single problem and discuss the pros and cons of each.
