Building AI products with stakeholders requires a fundamentally different approach than traditional software development.
From my experience working with AI, success depends not only on technical implementation but also on bridging the gap between AI capabilities and stakeholder expectations.
In this post, I’ll share lessons from guiding stakeholders through AI’s possibilities and limitations.

In my experience, organisational demands often override the focus on boundaries and domain-driven design. This reflects the tension between following technical best practices and delivering business outcomes quickly. While theoretical approaches are widely discussed at conferences, in books, and in videos, the practical implementation of these ideas is often shaped by cultural dynamics, resource constraints, tight deadlines, and internal politics.
In this post, we'll explore the challenges of maintaining boundaries and potential solutions, using a payment system as an example. This system facilitates transactions between clients and payment providers, such as PayPal or Stripe, highlighting the distribution of responsibilities within its architecture.

Knowing that the same code would always return the same output when given the same inputs was the foundation of everything we built.
We aimed for no surprises, no matter how complex a workflow might be. Whether implicitly or explicitly using finite state machines, this determinism enabled us to build testable, monitorable, maintainable, and, most importantly, predictable workflows.
We read and shared ideas at conferences, promoting patterns and principles like SOLID and DRY to create functional, composable, and extensible software.

New frameworks appear daily, each claiming to be the 'ultimate' solution for building AI agents, often backed by YouTubers enthusiastically promoting demoware and usually their own library, framework, or SaaS offering. Unfortunately, this enthusiasm can lead companies to uncritically adopt these tools without considering the long-term implications.
It's a well-known adage that naming things is hard.
In event-driven architectures, a consistent naming convention is essential for scalability, communication, collaboration and maintainability.
At the moment, I'm architecting a new event-driven solution, and I planning to adopt a Structured Naming approach for event types.
In this post I'll share my thoughts on this approach and its benefits.

The last thing I wanted to do was be a hero.
🎸 "Always keep on the right side of the path" – the Parkrun version of Monty Python's song.
I'd rather everyone enjoy a safe, smooth race where I can cheer and encourage people on as they pass, reminding them to keep to the right so they don't collide with runners coming the other way.
It's the same in the land of IT. The only thing I want to see when viewing Grafana dashboards is a sea of green, 200 status codes and steady traffic patterns.

Like many others, I have long been frustrated with platforms like Ticketmaster, See Tickets, and Gigs and Tours. This weekend, their reputations took another hit as fans faced inflated prices and technical glitches.
This made me think if I could design a better, more reliable ticketing system that prioritises fairness and user experience.

These individuals have inspired and challenged their teams and driven them to achieve their full potential.
What truly sets a leader apart, however, is their ability to motivate and their willingness to fight for their team.
There's something special about a leader who fights for their team.
In this post, I'll explain what happens when a leader truly stands up for their team, sharing my firsthand experiences from a transformative project at Cambridge Assessment in 2007.
As an England football fan, I know the feeling all too well. The heartbreak of watching your team come so close, only to fall short at the final hurdle once again. It's now 58 years of hurt.
It's a mixture of emotions – frustration, disappointment, and knowing the team could have done more.
I've experienced a similar feeling in my work as a consultant.
