Here are some things real, living, breathing humans have to say about working with me.
No AI or hostages* involved.

I first noticed Davis because of his passion for software—he was always building hobby projects and sharing smart takes on system design. That curiosity and drive led me to bring him in for an interview at Alloan, and it turned out to be one of the best decisions we made.
At Alloan, Davis was instrumental in shaping our backend infrastructure. He built scalable multitenant systems, integrated authentication with Azure Active Directory, and managed our container clusters with precision and calm. His work consistently raised the bar for technical quality.
Davis also leaned into LLMs early, using them to automate internal workflows and boost team productivity—proof that he’s not just great at today’s tech, but already fluent in what’s coming next.
On a personal note, Davis is just a joy to work with. He’s fun to play online games with, always up for a good laugh, and one of the most thoughtful people I’ve brainstormed with—on technical challenges or totally random topics.
Overall, deep backend expertise, a future-facing mindset, and great team energy.

The first thing that comes to mind when I think about Davis professionally is his incredible work ethic.
He is someone that is extremely passionate about what he does and strives to be the best at it.
I've had the pleasure of working with Davis for 3 years and he has been nothing short of dedicated, consistently demonstrating a commitment to excellence.
Davis is also a confident and natural leader and has led his team to success consistently regardless of the nature of task at hand, be it solving a critical issue or coming up with and implementing features that enhanced the product significantly.
Davis is also a very creative individual and this adds a unique dimension to his contributions. His innovative thinking and creative solutions bring a fresh perspective to every task, showcasing his ability to think outside the box.
Developers and managers are aplenty but those that always work with security in mind at the get go are hard to come by.
Davis is one such individual who is an advocate for good security practices in code which is a way of thinking that is ever more valuable today.
It's been an absolute privilege collaborating with someone so driven and focused on achieving outstanding outcomes. Davis' attention to detail and proactive approach significantly has and will contribute to the success of any project.
Needless to say, he will always be an extremely valuable asset to any team he's a part of.

Working with Davis at Alloan was an absolute pleasure. He's one of those rare people who brings together sharp thinking, a clear product vision, and genuine leadership skills—all in one.
Davis is super smart and always brings clarity to the toughest problems. Whether it’s figuring out product direction or diving into tricky technical issues, he’s someone you want in the room. He has a great sense of what matters, and that shows in both the decisions he makes and the way he works with the team.
What I really appreciated was how supportive he was to everyone around him. He takes the time to mentor juniors, share knowledge openly, and lead by example. You can see how much people grow when they work with him—he lifts up the whole team.
On top of that, Davis is just great to work with. Calm, thoughtful, and always approachable. You know things are in good hands when he’s involved.
All in all, Davis is the kind of teammate and leader any team would be lucky to have. I feel fortunate to have worked with him and can’t recommend him highly enough.

The Wall
I wanted to "master" tech - but it takes 10,000 hours of practice to achieve mastery. At the same time, some hours teach you much more than others.
I built an app to measure my activity not by hours, but "points" indicating the value it added.
The app visually displays the 10,000 hours goal as a wall of bricks to be built; the points contribute to the number of bricks.
Works on Windows, Linux and Mac for the easy dopamine hit.
When Covid hit, Zoho became WFH overnight.
We were required to use the Zoho People HR app to check in/out. Navigating to the website to do this was a pain.
This is a Chromium browser extension to view status and check-in/check-out in Zoho People from any tab in the browser, used by 200+ employees everyday.
Was useful till Zoho integrated this feature in their product a few quarters out.

A separate assistant app is too much friction: meet the user where they are.
So I built an agentic AI assistant to manage all aspects of my life: on WhatsApp!
Text it on WhatsApp, forward a message, ask questions and dump your tasks.
It takes care of the rest.
Exposed as a WhatsApp business app, the backend runs on a baremetal server on Hetzner.
Setting it up was...fun.

Has the iPod made us anti-social?
It sounds like a dystopian vision. Half of humankind wired up to a parallel universe that leaves them oblivious to their surroundings and fellow man.
The iPod has thus created a minefield over how to behave. "I wouldn't stop someone wearing those white wires to ask for directions. It's like they're putting up a big closed sign" Gordon notes.
Many iPod users told him they resented people interrupting their listening to talk to them.
A Muslim juror was discharged from a murder trial after being caught listening to her iPod under the hijab.
When entering a shop, should the user take off their headphones to talk to a sales assistant? Should they take one out? Or leave them both on and turn the volume down?
