Helping developers grow beyond the keyboard: in code, career & leadership | Co-founder @ INTELLI-T
Antwerpen, Belgium
Actions
I went from writing my first lines of code to co-founding INTELLI-T, and somewhere along the way, I discovered that the hardest bugs to fix aren't in your codebase. They're in how developers think about their craft and their career. I help developers grow beyond the keyboard: navigating interviews, stepping into leadership, and building the career they actually want. At INTELLI-T, we bring that same mindset to .NET projects, turning great developers into trusted partners for our clients.

Your career won't build itself
Most software developers can tell you exactly what's in their next sprint. Ask where they want to be in five years, and the conversation suddenly gets a lot quieter.
The biggest career mistakes rarely come from bad technical decisions. They come from career decisions we never consciously make. Staying too long. Saying yes too often. Chasing titles instead of growth. Assuming great work always gets noticed.
In this fast-paced session, we'll challenge some of the biggest assumptions developers make about their careers and explore the small decisions that quietly shape where you end up. You'll leave with practical insights to stop drifting, start making intentional career choices, and take ownership of the one project nobody else will build for you: your career.
Code isn’t everything: 10 Job myths Developers still believe
A quick, high-impact lightning talk revealing 10 common myths that can hold software developers back. This talk challenges traditional developer mindsets and encourages a broader, smarter approach to the craft.
This fast-paced talk will resonate with every developer and may be confronting to some that still believe common developer myths.
10 Interview hacks you need to know
Interviews can feel like a black box, until you’ve sat on both sides of the table as developer, coach and business owner. In this rapid-fire session, we’ll run through 10 powerful hacks to help you stand out, stay calm, and succeed in your next tech interview. No fillers, just practical, proven techniques to help you impress both the technical panel and the hiring manager.
Whether you are a junior or experienced developer, just graduated or self-taught professional preparing for your next interview. Join me in this lightning talk to ace your next interview
Cooking under pressure: why great developers fail tech interviews
Tech interviews are like being asked to cook a three-course meal in someone else’s kitchen while they watch, interrupt, and occasionally question your choice of salt.
You may be a great developer, but interviews often turn experienced professionals into nervous narrators of their own thinking. In this talk, we’ll explore why solid software engineers still fail interviews, how interviewers decode your answers, and where candidates unknowingly drop the pan on the floor.
We’ll replace guesswork with clear signals, show how to talk about your experience without overcooking it, and help you leave interviews sounding confident, credible, and ready to be trusted with the keys to the kitchen.
I’ve been the candidate getting rejected and getting hired. I’ve been the interviewer making the call, and later the coach and business owner helping others through the same process. This talk comes straight from those experiences: the awkward moments, the wrong turns, and the small changes that made a real difference.
Fast Code, Slow Growth? Developers in the Age of AI
AI has made developers faster than ever. Tasks that once took hours now take minutes. But this raises an uncomfortable question: are we actually getting better?
In this session, we explore how AI is changing the way developers learn, think, and grow. Why do some developers improve faster than ever, while others plateau? Why are junior developers both empowered and at risk?
From a mentor’s perspective, you’ll gain a clearer understanding of how AI shapes your growth as a developer and what it takes to stay sharp in a world where speed is no longer the differentiator.
From coder to coach to business owner, I’ve seen what it takes to grow at every stage of a developer’s career. As AI reshapes our industry, that growth is becoming both harder and more important than ever. I help developers build the skills and mindset needed to stay sharp and use AI to their advantage.
I just wanted to write code: becoming a leader in a tech team
At some point in your career, you don’t apply for leadership. It just shows up. People start looking at you in meetings, asking for your opinion, and expecting you to “handle things”, even though your title still says developer.
This talk is about that quiet shift and what happens when your impact starts extending beyond the code you write. Through real stories, mistakes, and lessons learned, we’ll explore how developers become leaders, why some of the habits that made us successful stop serving us, and what it takes to guide a team without formal authority.
Expect practical insights on creating ownership, building trust, giving feedback, influencing decisions, and helping others grow. Just very practical lessons I wish someone had taught me years earlier.
The career advice every software developer needs
Software developers spend years learning how to write better code, design better systems, and solve increasingly complex technical problems. Yet almost nobody teaches us how to build a successful career.
Why do some developers seem to create opportunities wherever they go, while others with similar technical skills quietly plateau? Why do promotions sometimes go to someone else? When should you stay, when should you leave, and how do you know if you're actually growing or simply repeating the same year of experience?
Drawing on years of interviewing candidates, mentoring developers, leading engineering teams, and running a software company, I'll share the career lessons I wish someone had taught me much earlier. We'll explore the decisions that shape your career: from learning, visibility and ownership to negotiation, AI, career growth and avoiding the traps that silently slow your progress.
No management theory or generic motivational advice. Just practical insights, real stories, and honest lessons to help you build a software career with intention instead of leaving it to chance.
I've spent years helping developers grow, not just technically, but professionally. Through interviews, mentoring, leadership and running a software company, I've seen what helps careers accelerate and what quietly causes them to stall.
