Řekli to za mě lépe — 20+ engineering leaderů.

"Marian was part of helping scale up our technical teams from 35 to 100 people during his time with Mews. One of his key successes was around creating visibility on engineering output and ensuring we were able to more effectively reach our goals."

"Marian is an experienced and polished software architect with excellent communication and interpersonal skills. I had the fortunate opportunity of creating an engaging and productive working relationship with him soon after joining the company as CTO. The intersection of his technical background and his well-rounded nature allowed us to drive a higher level of strategic thinking across the engineering organization."

"Marian helped me to stabilize and mature our engineering in Apify after a period of growth. In mentoring, we focused on many areas across product-engineering cooperation, career framework, team alignment, and agility. But mainly, he changed how I view my role and the role of the engineering department in the organization."

"Marian's expert participation in the recent audit of our Core Banking in-house solution was invaluable. His work primarily focused on evaluating the scalability and performance of the system under peak usage scenarios and projected user growth. His analytical skills and understanding of system architecture enabled him to effectively assess the system's ability to handle the stringent demands of our monthly bank closure procedures combined with peak user access. His recommendations extended beyond technical solutions, offering strategic advice on improving the overall robustness of the system."

"Marian has been incredibly helpful in my professional development. In my conversations with him, he helped me transition from an operational role to a more strategic one. He not only showed me how to grow a team, but also emphasized the importance of understanding the "why" behind it. In each session, he provided me with practical tips and recommendations for tools and other valuable resources."

"Marian excels at taking the theoretical knowledge you can read about in books and putting it into practice in your field. I wanted to accelerate change within a few months, and he has done just that. We are a prime example of how internal development teams can bring new products and services to a traditional organisation and truly digitise the old-fashioned business with rapid software product discovery, delivery and adoption."

"Marian provides a wide variety of services, from high-level leadership and C-level mentoring to best practices for engineering teams. We spent a couple of months together during our mentoring sessions, which led to my personal growth, increased efficiency among our teams, improved transparency, and overall satisfaction within the team. I totally recommend any kind of cooperation with Marian."

"Marian is a true professional with vast experience. I was pleased to work, learn, and discuss essential development matters such as SDLC, OKRs, and team management tactics with Marian at our 15+ sessions. I admire how Marian is organized and his passion for deep diving into different areas of expertise. I recommend Marian with complete trust."

"Marian was my mentor for 3 months and I've learned a lot from him — communication with my own team and stakeholders, managing improvement plans, hiring, and overall team stabilisation. Marian has experience from multiple scale-up companies, growing from 30 to 100+ people. What I appreciated a lot is directness and honesty in mentoring, challenging my own beliefs of what is possible and at the same time being very human oriented."

"I have been working with Marian for more than eight months. He helped me and my team with roadmap transparency. He taught us how to measure the right things with value, build the roadmap, and create the discovery, delivery, and adoption circle. And most importantly, have the satisfaction of creating real value. By learning from him, you can easily save your organization from many dead ends."

"I worked with Marian for a little over 6 months, and right from our first call I realised this was going to be a fruitful and insightful coaching opportunity. Our sessions were always collaborative and bidirectional, informal yet professional. Marian has a wealth of knowledge in leadership and software development management and he was always able to jump into any kind of topic or question I had, offering practical and proven solutions."

"I had the pleasure of being mentored by Marian. He provided me with guidance and valuable tips during my transition into a manager position. As a skilled mentor, Marian was able to guide me through various topics and offer particularly practical advice. I highly appreciate the time he dedicated to me, and it undoubtedly had a significant impact on my professional growth."

"Marian has been mentoring me for a year and a half. What I appreciate the most is that no matter what topic I bring up, Marian always has practical and actionable advice. We've covered layoffs and hiring, performance reviews, communication with CxO levels, scaling and consistency. In my new role, after just four months, I had to let go of a significant number of people who were also my friends. Marian provided invaluable guidance on how to approach this difficult task. I was able to part ways with everyone on good terms."

"I started working with Marian just before our start-up, Manta, was acquired by IBM. Marian helped me during the 8-month integration period to navigate a completely new environment and focus on what's most important. We covered operational topics — how to communicate the integration timeline, how to ensure smooth transitions, how to have a clear roadmap. But we also discussed change management, decision-making, presenting successes, and communicating in critical situations."

"There is no other mentor like Marian. Each session, each talk we had was inspiring and full of practical recommendations. He helped me to switch thinking from what I want to do as an engineer to what actually helps the product and the team. I started applying his recommendations and not only did it start to bring value to the product, it feels so good."

"Marian helped me a lot in my beginnings as a manager. He designed a company-wide program for beginning managers at Mews which in my view makes Mews one of the best companies for managers where to start. He helped me to avoid many initial mistakes and gave a lot of useful advice for the future. Marian is a true leader with a human approach worth following."

"Marian's wealth of experience was incredibly valuable to me. Marian has taught me to look beyond daily tasks and set long-term goals. This shift in perspective has greatly enhanced my planning and strategic thinking. Thanks to Marian, I was able to share my insights as a speaker at the Engineering Leaders meetup, an enriching experience in my career path."

"When I first took a leadership position and became a tech lead, I was very fortunate to come across Marian. Every session was driven by my current needs, but I appreciated that Marian had well-thought-out and structured curriculum notes and examples. His resources appeared to be pretty much bottomless — OKRs, planning, prioritization, 1-on-1s, perf reviews, navigating tech lead responsibilities. He struck me not only as a great mentor, but a person I'd happily collaborate with in pretty much any context."

"Over a six-month period, Marian served as my mentor and coach, during which time he greatly enhanced my ability to concentrate. Our focus shifted from day-to-day tasks to strategic thinking. I've improved how I manage my schedule and communicate with various stakeholders, both within and outside my organisation. I particularly value Marian's knack for highlighting the important issues and identifying the minor problems that distract me."

"When you start as the first agile coach in a company with more than 100 developers, your challenge to find your way is real. Luckily I had Marian as my manager at that time. He gave me all the support I needed and wanted to set me up for success. By giving me the space, time, insights, and most importantly the trust in what I can bring, he really gave me all the energy I needed."
