He went on to assume a global role as a leader of a working subgroup that proved to be the most successful at the end of the 6 month pilot run. When he visited Asia, Marcin made special arrangements to be in Singapore and proposed to meet other high potentials which was not previously practised by others in a similar capacity. Marcin clearly exhibits all the essential traits of a global manager who is culturally sensitive, communicates well (both verbally and written) and has a geniune interest in helping others to succeed. His strong collaborative skills coupled with his interest to learn new things will bring him closer to his career goal within a short period. His dedication to this project work has earned him my support in all his career endeavours." ✅#2 - Marketing Director at Luxoft: "I had a privilege to work with Marcin on the same team at Luxoft where he was leading the go-to-market campaign for one of the company’s top products, the Horizon visualization software for the banking industry, while I was focused on the automotive side of business. As peers, we talked and exchanged ideas on a regular basis. I was always amazed at Marcin’s ability to think outside the box. Often working under tight deadlines and budget limitations, he would always manage to deliver an effective and elegant solution, whether it’s a piece of marketing content, media outreach, an industry event or a social media campaign. Marcin’s understanding and knowledge of digital marketing is second to none. He is a true digital native who knows how to get the marketing message across the social media. Last but not least, Marcin is a fantastic person to work with. Sensitive to other people’s needs, he was always willing to help and support his team members, and to share his knowledge generously. And he did it all with a positive attitude and a terrific sense of humor. Marcin would make a great addition to any marketing team as a member or leader. " ✅#3 - Founder & CEO at Piercing View (Upwork project) "MJ is a very accomplished strategist. He has been extremely valuable in developing our marketing strategy, identifying high value targets/clients, and crafting the appropriate 'pitch' for each unique circumstance. Thank you!"
