I work with organizations to turn operational complexity into systems that scale.

I design human-centered, cross-functional solutions that reduce organizational drag, strengthen governance, and ensure your tools work the way your people work.

This page is designed to give you a clear sense of my approach —

My intent is to make it easier to evaluate whether I’m the right partner for your organization.

and the kinds of challenges I solve.

Operational Debt

I remove years of operational debt by connecting leadership's needs with on-the-ground workflows, and inserting governance that secures real adoption — and I do it in a human-centered way.

My value isn’t just technical expertise — it’s how I see systems.

I bridge the gap between leadership’s vision and the way work actually happens on the ground — my work slots in within your strategy but above daily operations, technical tooling, and systems — it has altitude.

That’s governance — the decision clarity, ownership, and structures that support real adoption.

Tools follow the logic — not the other way around.

This approach reduces risk, prevents rework, and makes adoption easier because the system reflects your real operational reality.

  • Clarity before strategy.
  • Strategy before building.
  • People before process and tech.

I use a mix of top-down and bottom-up planning to make sure we’re capturing the real way your organization operates — not an idealized version that was documented years ago.

There's nothing wrong with idealized workflows. Visioning — or "dreaming and scheming" as I like to call it — is part of leadership.

But systems that stick are those designed to meet you where you are now, while avoiding the operational and technical debt that shows up later by skipping steps.

Mixing top-down + bottom-up works because:

  • Decision-clarity before strategy → gives clear authority.
  • Strategy before building → builds the right solution.
  • People before process and tech → allows adoption to start on Day One.

Adoption is the strategy.

My approach isn’t about control or removing agency — though it does require explicit authority.

I don't care much whether authority is on your side, with me in an advisory role, or my side, with me as architect — but authority cannot be split.

I begin with decision clarity and responsibilities of the project first, then within your organization.

Strategy only works (and tooling only matters) when decision rights are explicit and consequences are owned by roles, not people.

If it's not safe to fail, it's not safe to succeed, either.

In other words, if you want your team to take measured risks that further your organization, they need the rights and the wiggle room to do it — even if it is not always successful.

Many organizations attempt to answer the technical part of the equation too early — and sometimes in lieu of governance of process.

My process flips the traditional order. I put authority clarity first because that’s where the unnamed gaps — and the real risks — live.

Starting here stabilizes the entire build (and operations downstream) by preventing operational debt and improving adoption.

Clear roles are imperative.

Collaboration only truly works when everyone knows who holds what and why, and when helping is not converted into job or scope expansion by default.

Conscientiousness cannot be exploited — even inadvernently — without creating operational debt.

We name the following things explicitly — without retroactive expectations or blame.

Some may seem obvious, but in practice may be more implied than locked in.

  • Who's holding what, and why
  • How decisions get made, and by whom
  • What's involved in the flow of work
  • Where and why things get stuck or dropped
  • Where and how your values are supporting operations (or not)

These are the details that really matter for system adoption.

They also matter for data provenance & lineage.

Not the features.

Not tools.

Not pretty dashboards.

We can do all those things, but they're the icing, not the cake.

It's the clarity of structure and decisions — even for smaller, leaner organizations — that lays the foundation for smooth operations and systems that stick.

P.S. Automations and integrations — and especially Gen AI — are introduced when they truly create more ease and efficiency, rather than simply increasing need for oversight.
