Sentinel: Your Web-Performance Watchman

Workshops and Training

Your team armed with my knowledge.

I got a lot of feedback from the attendees here and they loved it. They asked if we could do more with you, possibly get more time. People who do workshops for us are appreciated, but the feedback I got with what you did was something else.

As a consultant, it is my job to inform and educate. One of the most effective ways to do that is through practical, focused workshops.

With a 99% approval rating, my workshops are not your typical corporate training session. They’re intense, intensive, and packed with real-world, practical insights. I’m a teacher who does.

Topics, format, and content can be worked out together to best suit your needs, but generally speaking, we’ll be focusing on the entire gamut of front-end web performance: tooling, techniques, case studies, insider knowledge, tips, tricks, and a whole lot more.

We’ll look at your own sites and products as I take your team through the exact steps needed to correctly identify and address site-speed issues. At the end of it all, you end up with an up-skilled team and a faster website. It’s a win-win.

Organise a Workshop

Lockdown Learning

Missing conferences? Wanting to keep your team sharp during times of no travel? I’ve written an entire workshop, Web Performance Back to Front, designed specifically for remote delivery. Delivered to teams anywhere—or all over!—the world, optimised for highly practical online delivery, and recorded for you to keep forever.

If we go on to work together, I’ll fully refund the cost of the slides—I don’t want you to pay me twice.

Got Questions?

Do you run workshops remotely?

Yes! Owing to 2020’s Coronavirus pandemic, I designed a workshop curriculum and format specifically optimised for remote delivery. Learn more…

How many people can attend a workshop?

The good news is that I don’t base workshop pricing on the number of attendees. Making it harder for people to attend will minimise my impact, which defeats the whole purpose of training your team—send as many people as you want!

That said, I would recommend trying to keep numbers under 30. Beyond that amount, sessions tend to turn into more monologue, lecture-style sessions that hinder both interactivity and productivity.

How long do workshops last?

At least one day—a half-day isn’t long enough to cover anything of real substance. I recommend running a two-day workshop so that day one can be spent learning, and day two spent implementing. It’s hugely valuable to host a second hackathon-style second day so that your team can begin to put their newfound knowledge into practice with my guidance.

Beyond that, we can design week-long bootcamps, quarterly refresher sessions, and more. It all depends on what you need and what will provide you with the most value.

As always, the best option is to contact me to start a no obligation discussion to see what will work best for you.

Can we live-stream or record workshops?

If you have the ability to do so, then yes! Live-streaming means you can open the sessions up to remote members of the team.

Can we choose workshop content?

Absolutely! We’ll work together to design an itinerary that will best suit your team and projects. There’s no point looking at e-commerce case studies if you’re a publishing house! We can jump on a call ahead of our engagement to go over particular areas of interest and draw up a workshop that’s going to deliver maximum value.
