Marian excels at taking the theoretical knowledge you can read about in books and on the internet and putting it into practice in your field. You can get lost in so many ways when it comes to bringing technological innovation into companies and getting it accepted by customers and users. I wanted to accelerate this 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 the traditional organisation and truly digitise the old-fashioned business with rapid software product discovery, delivery and adoption. I am happy to discuss in more detail how he was the important part of this change.

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.
Marian has a great success story and knowledge behind him. By learning from him, you can easily save yourself or your organization from many dead ends and use shortcuts to succeed.

When I first took a leadership position in my career and became a tech lead, I was very fortunate to come across Marian, who mentored me for about six months. Thanks to him, I was able to quickly ramp up in my new role, feel more confident, and be more productive when facing challenges I hadn’t encountered before.

Every session was driven by my current needs at that moment, but I appreciated that Marian had well-thought-out and structured curriculum notes and examples he could reach for when we discussed a specific topic. His resources appeared to be pretty much bottomless. These included OKRs, planning in general, prioritization, 1on1s, perf reviews, navigating tech lead responsibilities, and many more.

In a relatively short period, Marian helped me not only vastly enhance my knowledge, but also imbue me with his never-ending drive and energy. He struck me not only as a great mentor, but a person I’d happily collaborate with in pretty much any context. Thank you Marian for making me a better tech lead right from the start!

There is no other mentor like Marian. Each session, each talk we had was inspiring and full of practical recommendations.

I started applying his recommendations and not only it starts to bring value to the product it feels so good. Thank you Marian.

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 has a wealth of knowledge and experience, and is always willing to share it with others. I highly recommend him as a mentor to anyone looking to improve their leadership and management skills.

CTO at Apify, the web scraping and RPA platform.

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 was my mentor for 3 months and I’ve learned a lot from him – communication with my own team and stakeholders, managing improvement plan in the team, hiring of new people, and overall teams stabilisation. Marian has experience from multiple scale up companies, growing from 30 to 100+ people and that’s experience he can pass on to engineering managers and engineering directors. What I’ve 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 would recommend Marian as a mentor to anybody who really wants to grow in managerial role as few hours per week I’ve invested are several months saved on the journey.

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.

Senior agile coach

When you start as the first agile coach in a company where you have more than 100 developers then your challenge to find out your way is real, luckily I had Marian as my manager at that time where he gave me all the support I needed and also he wanted to set me up for success.

By giving me the space, time, insights, and most importantly the trust in what I can bring really gave me all the energy I needed.

By having Marian as a leader and a true enabler I never hesitated to experiment with ways of working, practices or strategies.

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 where always collaborative and the discussions bidirectional, informal yet professional. Marian has a wealth of knowledge and experience 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 to problems.

I personally look forward to future opportunities to work with Marian, and can only strongly recommend him if you are looking for mentor or coach.

Chief Digital Officer @TrinityBank
I am pleased to recommend Marian Kamenistak, whose expert participation in the recent audit of our Core Banking in-house solution was invaluable. Marian’s 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.

Marian’s contribution was crucial in formulating a set of recommendations that were documented in the final audit report. His insights helped ensure that our architecture could scale to accommodate an expected annual increase of users annually. The final document not only presented a confidence score assessing the system’s current capabilities but also outlined necessary architectural enhancements and associated timelines and costs.

Additionally, Marian’s recommendations extended beyond technical solutions, offering strategic advice on improving the overall robustness of the system.

It was a pleasure to work with Marian on this critical project, and I am confident in his ability as an auditor and systems architect. His contributions have left a lasting positive impact on our operations.
