I've engineered the web since 1996 and founded companies around it. That mixture is what makes my trade-offs punch above their weight.

Three pillars

Your team has the talent. They're missing the sparring partner.

Your seniors are solid. But they hit ceilings they can't name - in architecture, in decision-making, in leading others. What they need isn't a course. It's someone who's been 10 years ahead and can meet them where they are.

The pattern I keep seeing: teams don't lack talent. They lack someone who challenges their thinking at the right level - architecture decisions, trade-off reasoning, technical leadership. A course won't fix that. What works is a sparring partner who's been through it and can meet your people where they actually are.

I do engineering since 1994. Web engineering since 1997. I co-founded Qafoo, where I spent 9 years doing nothing but consulting, training, and mentoring engineers on software quality. After that, I co-founded a startup, served as principal engineer, and grew a team of 20+ engineers from scrappy MVP to successful exit. That's the depth I bring into your team. And if there's one thing I've proven over all those years, it's this: I make people around me better at what they do.

Turn "engineering says no" into a conversation both sides can win.

Engineers guard their technical decisions. Business people accept what they don't understand. The result: decisions made in a vacuum on both sides. I open up the technical solution space and explain it in terms business can actually weigh. So when your team buys technical debt, everyone knows the price - and everyone stands behind paying it back.

"Just give us the requirements, the technical decisions are ours." Engineers say this all the time. And they're wrong - not because business should dictate technology, but because locking business out of the technical solution space means they can't weigh the trade-offs that affect their roadmap, their budget, their timeline.

I've spent years sitting between both sides - at Qafoo with clients, and at Frontastic where I co-founded the company and worked daily with business leadership. I map out the technical options and explain them in terms business can actually evaluate. The result: when your team decides to take on technical debt, the business side understands what they're buying and stands behind the plan to pay it back. And the best part: this is a skill your technical staff can learn from me. I don't just bridge the gap - I teach your people to bridge it themselves.

Adopt AI workflows that survive past the first demo.

"Let everyone experiment with Copilot" is not a strategy. Agentic engineering changes how your entire product-engineering organization works - not just how individual developers write code. QA, support, product, engineering - they all need to pull in the same direction. That takes structured guidance, not a lunch-and-learn.

Most companies right now are somewhere between "a few engineers play with Copilot" and "we bought an enterprise license, now what?" Neither is a strategy. Agentic engineering is a fundamentally new way of working. It doesn't just affect how developers write code - it changes workflows across your entire product-engineering organization. QA, support, product, engineering - they all need to pull in the same direction.

There are a lot of people selling you magic AI transformation right now. Most of them learned this stuff last month. I build real projects with agentic tools, I mentor companies who adopt agentic engineering in practice, and I exchange daily with a large engineering community on what actually works. On top of that, I bring 25+ years of engineering discipline to a field that has no elders yet. That's the difference between a demo and a practice.

How we could work together

I don't sell packages. Every engagement starts with understanding your situation and then finding the format that actually fits - whether that's a focused workshop, ongoing sparring, or something we haven't named yet. Here are some examples of how companies typically work with me. Think of them as starting points, not a menu.

Agentic Engineering

From Experiment to Practice

Your team is experimenting with AI-assisted development, but nothing sticks. Individual engineers play with tools, some love it, some resist it, and there's no shared way of working. Output goes up in some places while review bottlenecks explode in others.

I start with a 2-day on-site workshop with 2-3 of your most interested and skilled engineers. We analyze your codebase and the full process around it - how requirements come in, how your teams collaborate, how QA, deployment, and all other functions involved in your delivery chain work together. From that, we craft an agentic workflow tailored to how your organization actually operates - including all required artifacts and tools, such as context files, skills, and prompt structures.

We then introduce the workflow to a single team in a dedicated full-day hands-on session, where they work through their first real tickets using the new process with me in the room. After that, the team pilots the workflow for the first couple of iterations on their own. The goal: test real-world acceptance, see if quality holds up, and refine the process based on what actually happens when it meets daily work. I stay available on a regular basis for guidance and feedback during this phase, typically for 4-8 weeks.

Once the workflow proves itself, we roll it out to additional teams - each with their own hands-on introduction and guided pilot phase. After the broader rollout, we evaluate together: what works, what needs adjusting, what's next. From there, we can bring in the departments attached to engineering - product, QA, support, and others - helping them integrate into the agentic way of working. This can start during the rollout if you're ready for it.

Three things matter throughout: engineers need to feel confident that this helps them, not replaces them. The workflow must improve actual team output, not just generate more lines of code. And everyone involved works in a shared, structured way - with clear guardrails, but enough autonomy for each team to make it their own.

Engineering Excellence

Architecture, Quality, Process

Technical debt is piling up. Scaling issues surface at the worst possible times. Bug rates are creeping up, velocity is quietly declining, and your team spends more time firefighting than building. Maybe it's the architecture. Maybe it's testing. Maybe it's the deployment pipeline. Maybe it's all of it. You need someone who can look at the whole picture and tell you where to start.

I begin with a workshop with your senior engineers and leadership - understanding your challenges, your goals, and where you want to go. Then I step back and do the deep work: I research, I analyze, I talk to the relevant stakeholders where I need further clarification or alignment, and I think through the options and their consequences properly. The result is a recommendation paper - an honest analysis of your situation, evaluated approaches with trade-offs clearly named, and a clear recommendation with reasoning for why I lean a certain way.

We discuss the paper together, remote or on-site. You might find you can take it from there on your own. Or you might want me to help execute: on-site workshops with the affected teams, hands-on architecture work, concept papers, training on specific methodologies, review sessions. How we work together from there is entirely open - we find whatever shape fits your situation and your team best.

Leadership

Sparring for Engineers Stepping Up

You have an engineer who just became - or is about to become - a staff or principal engineer. They're strong at what they do. But the new role is a different game: leading larger groups, making architectural trade-offs with lasting consequences, mentoring others, handling conflict, and setting up processes like RFCs and architecture decision records. They need a sparring partner who's been there - and who isn't their boss.

I start with a half-day on-site session, 1-on-1 or with up to three people in similar positions. We set baselines: where are they, what are their challenges.

Then we move into regular remote sparring sessions - typically one hour on a regular basis, as frequently as needed. I invest time between sessions thinking through their specific situation. We work on concrete things: how to help a junior engineer who's struggling, how to scope a large refactoring effort, how to run a productive review, how to measure progress without making people feel controlled, how to handle engineers who push back against new ways of working.

This is a confidential space - they can ask things openly, without it leaking into their performance review. I've been a principal engineer myself, and I know what the job actually looks like on a Tuesday morning.

Business

Engineering Alignment

Your business and engineering leadership mean well but talk past each other. Priorities shift without shared understanding. Engineers feel steamrolled; business people feel blocked. Decisions happen in silos.

Before bringing both sides into a room, I talk to each party separately - engineering and business - in a confidential setting. I want to understand their actual situation, their motivations, what they're trying to achieve. I can do this because I genuinely understand both worlds: I've worked in technical roles for over 25 years and I've co-founded and led multiple companies myself. I know what keeps a CTO up at night - and I know what keeps a CEO up at night.

Then we come together for a 1-2 day workshop where I translate between both views, make the invisible visible, and help both sides arrive at a shared understanding. I document the outcomes - a report both sides can commit to.

From there, we can move into long-term coaching: I help set up and moderate regular alignment meetings where real issues get discussed honestly. New customer priorities, unexpected technical challenges, resource trade-offs, incidents - all the things that erode shared understanding over time. My role is to be the sparring partner for both sides and to keep that honest conversation going.

More of me

Why rent the Toby?

Built it, shipped it, sold it.

I'm not an advisor who watched from the sidelines. I co-founded Frontastic, wrote a lot of the initial code, served as principal engineer, grew the engineering team to 20+ people, and helped take it to a successful exit. Before that, I co-founded Qafoo - a consulting company for software quality that I ran for 9 years - and out of that, we founded Tideways. When I tell you a decision will hurt in 6 months, it's because I've made that decision myself - with my own company's money on the line - and felt the consequences.

Teaching is the craft, not a sideline.

My apprenticeship final exam was a self-created seminar. I've been giving conference talks and workshops since 2003. At Qafoo, training and mentoring engineers was the entire business model for 9 years. This isn't something I added to my profile because it sounds nice. Making people better at what they do is the thread that runs through everything I've done.

Across industries, across priorities.

Finance, component libraries, CMS, eCommerce, open source - I've built web applications and distributed systems across all of them. My hands-on depth is in PHP, JavaScript, and TypeScript. What that breadth taught me: the most important part in engineering is the business goal. Beautiful code is only well invested if it serves a purpose. That shift in perspective - from craft for craft's sake to craft in service of outcomes - is what I bring into every engagement. And yes, I've seen enough hype cycles to know which ideas survive and which ones quietly disappear from the roadmap.

Pragmatic, not dogmatic.

I completed an apprenticeship as an IT specialist before earning my diploma in Computer Science. I have the formal education. I know the theory. I also have the real-world discipline to know when to ignore it. Every architecture, every process, every tool choice is a trade-off. I don't sell silver bullets - I help you find the trade-off that fits your situation, your team, and your timeline. And I don't just help you execute on it - I enable your team to make these trade-offs themselves, long after our engagement ends.
