Proof that the operating system matters.

“I worked with Kristóf for several years at Profession.hu, where he worked as a Senior Project Manager within the PMO team under my leadership. Kristóf stood out not only for his ability to successfully deliver complex initiatives, but for the lasting impact he had on how our project organisation operated. He introduced practical frameworks for planning, estimation, and portfolio management, along with tools that significantly improved transparency and consistency across projects. Many of these practices defined by us, became embedded in our everyday operations. Beyond project delivery, Kristóf actively helped strengthen the PMO as a professional capability within the company. He regularly shared his knowledge through workshops, mentoring, and coaching, supporting fellow project managers and other departments in adopting more structured and effective ways of working. What I particularly valued in Kristóf was his ability to combine methodological thinking with a pragmatic understanding of organisational realities. His proactive mindset and focus on scalable practices contributed meaningfully to improving how projects were governed and delivered across the organisation. Kristóf is the kind of project management professional who doesn't just manage projects, he improves the systems, frameworks, and capabilities that enable organisations to deliver change more effectively. I would gladly work with him again.”

“I had the pleasure of working with Kristóf for about 4 years, where he served as the Delivery/Project Manager for our B2C delivery team while I led the B2C product management side. In that time, he became one of those colleagues I genuinely loved working with, and also someone who I happily call a friend. Kristóf has a real talent for keeping a delivery team running smoothly, from supporting junior developers to product managers and designers, making sure every sprint stays on track, and maintaining a sharp eye on capacity and team velocity. But what sets him apart is that he doesn't stop there. He constantly looks for ways to improve how the team works in the long run. One great example: he introduced an estimation methodology that not only helped developers give more accurate estimates, but also made planning significantly more predictable for the product side. That kind of cross-functional thinking is hard to find. He's the type of person who can't settle for "good enough". He always wants to improve and optimize, and that energy is contagious. Working alongside him made the team better at their job. On top of all that, Kristóf is just a great person to share an office (or a Teams channel) with. Kind, collaborative, good sense of humor, though I'll let others judge his dad jokes for themselves. :) I'd recommend Kristóf without hesitation to any team that values both operational excellence and a culture of continuous improvement.”

“I had the opportunity to work closely with Kristóf Frey for several years at Profession.hu while we were building a new product and the delivery organisation around it. When Kristóf joined, our team was still small and focused on developing a single emerging service. As the product matured and new opportunities appeared, the scope of our work expanded significantly and the team grew into a full delivery organisation responsible for multiple services. Kristóf played a central role in making that growth possible. Rather than simply managing projects, Kristóf focused on building the frameworks and operating model that allowed the team to scale. He introduced practical delivery methodologies, planning practices, estimation approaches, and governance structures that created clarity and predictability in how we delivered products. These frameworks became the foundation of how our teams worked together and enabled us to consistently deliver high-quality services as the organisation grew. Beyond project execution, Kristóf actively helped strengthen the broader delivery capability of the organisation. Through workshops, mentoring, and knowledge sharing, he supported colleagues in adopting more structured ways of planning, coordinating, and executing complex work. What I particularly valued in working with Kristóf was his ability to translate project management frameworks into systems that teams can actually use. His approach combines methodological depth with pragmatism, always focusing on what will make teams more effective and organisations more scalable. Kristóf is someone who doesn't just deliver projects — he builds the delivery capability and operational structures that allow organisations to execute consistently and grow. I would gladly work with him again.”

“I worked with Kristóf Frey for several years at Profession.hu, where he was the Delivery Team Manager responsible for the teams I worked in as a Senior Full Stack developer. Kristóf's impact went far beyond coordinating delivery. He built the operational framework that allowed our teams to work effectively and scale as our products and services grew. He introduced clear planning structures, prioritisation practices, and delivery processes that created alignment between product, engineering, and business goals. For developers, this clarity was extremely valuable. We understood the priorities, the risks, and the broader context of what we were building. This allowed the team to focus on delivering stable, well-engineered systems without constant firefighting or last-minute surprises. As the organisation expanded, the frameworks and methodologies Kristóf introduced became the foundation of how multiple teams operated. What started as a small delivery effort evolved into a structured organisation capable of developing and maintaining several services — and Kristóf's delivery architecture played a major role in making that possible. Kristóf combines strong methodological thinking with a pragmatic understanding of how product teams and engineering organisations actually work. He builds the systems, structures, and team environments that allow organisations to deliver complex products consistently. I would gladly work with Kristóf again and strongly recommend him to any organisation looking for someone who can build and scale high-performing delivery organisations.”

“I had the opportunity to work with Kristóf for nearly four years at Profession.hu, where I was part of the team as a Senior Manual QA Tester. What stood out to me most during our collaboration was his ability to improve the way a team operates without introducing unnecessary process overhead or bureaucracy. Kristóf didn’t just coordinate projects — he consciously shaped workflows in a way that made day-to-day collaboration more predictable, smoother, and less stressful for everyone involved. From a QA perspective, this made a significant difference. It is much easier to deliver high-quality work in an environment where information doesn’t arrive at the very last moment, where there is enough visibility to think ahead, identify risks early, and involve the right people at the right time. Kristóf consistently helped create that kind of environment. He encouraged proactive thinking instead of constant firefighting. One thing I particularly appreciated was that he never tried to force “textbook” processes onto the team. He listened carefully to feedback, understood how we actually worked, and adapted improvements to fit the reality of the team. Because of this, changes felt practical and natural rather than imposed. In my experience, one of Kristóf’s greatest strengths is recognizing where collaboration or delivery starts to break down and finding ways to improve processes so they genuinely support the team instead of becoming additional burden. On a personal level, he was also a pleasure to work with: calm, approachable, supportive, and always open to questions, ideas, or concerns. I would gladly work with him again and can wholeheartedly recommend him to teams and organizations looking to build more structured, predictable, and effective project and delivery processes.”

“I’ve worked with Kristóf for over four years, and I can honestly say he is the best Project Manager in the world. I’m absolutely gutted to see him leave our team! He is simply next-level—the kind of leader who jumps right into the trenches to solve problems and actually listens when you bring new ideas to the table. But what makes him truly special is how much he genuinely cares about the team’s well-being and everyone’s opinion. On a personal note, Kristóf has been an incredible support to me both professionally and personally every step of the way. I’m going to miss his positive energy, his guidance, and just working with such an awesome guy every day. Any company out there would be unbelievably lucky to have him on their side!”
