“I had the pleasure of working alongside Dmytro during our time at MapR, and I'm thrilled to provide a glowing recommendation for him. Dmytro is undoubtedly one of the most exceptional engineers I've ever had the privilege of collaborating with, particularly in the realm of Big Data and its associated ecosystem, which includes technologies such as YARN, HBase, Kafka and ZooKeeper. He is equally proficient in Operating Systems and Network technologies. Dmytro consistently demonstrated his expertise and unwavering commitment to helping both our team and customers whenever issues required escalation. His proficiency in troubleshooting large-scale production clusters, often comprising over 1000 nodes, was nothing short of remarkable. Dmytro was adept at identifying and resolving highly escalated performance issues and bugs related to key components like YARN, HBase, and Kafka. He not only excelled in diagnosing issues but also played a pivotal role in fixing code for various products, including YARN, HBase, and Kafka. Subsequently, he assumed the role of a developer for the Apache Kafka project, further showcasing his versatility and skills. In our shared experience spanning several years within the organization, Dmytro consistently maintained a 100% success rate in tackling the most challenging problems in both software development and customer operations. His profound and extensive knowledge of software development, operations, and networking, coupled with his determination to unravel even the most complex technical challenges, truly set him apart. Furthermore, Dmytro's respectful, responsive, and supportive demeanor endeared him to colleagues and clients alike. It comes as no surprise that Dmytro commanded immense respect within the organization, and his departure left a void that was keenly felt by the entire team. I wholeheartedly endorse Dmytro as a tremendous asset to any organization and extend my best wishes for his future endeavors. I genuinely hope that our paths will cross once again in the future. Please do not hesitate to reach out to me for further insights or details.”

Dmytro's very deep and broad knowledge of software development, operations and networking, combination of talent and will to get to the bottom of technical challenges are outstanding. In a few years that we worked in the same organization, working shoulder to shoulder on a number of distributed system components, his success rate was constant 100% on most challenging problems both in software development and customer operations. On top of that, Dmytro is respectful, responsive and helpful person. No surprise such combination of technical and soft skills gained him enormous respect in the organization. I still remember the day and how sad everyone in the team was when Dmytro's leaving announcement was made.

“Java/Python developer with experience in big data / Hadoop ecosystem projects. Responsible, able to focus, fast learner, able to interact with a team.”

“Dmytro is a rare talent. He worked with me on the Apache Ambari project and specifically on scaling Ambari Metrics Service backed to support the ingestion of 1 billion+ events per day into HBase and being able to query it in real-time using Grafana dashboards. I can fully attest to his clear Engineering mindset and ability to solve complex problems independently and within a team. He would be a great hire.”

“I highly recommend Dmytro for his extensive knowledge of big data and ability to apply it to complex problems, as well as his strong leadership skills as a team lead and valuable contributions consistently demonstrating dedication to customer satisfaction.”

“Dmytro has been running a team of backline support engineers related to Big Data/ Hadoop stack in the CYberVision for about 4 years. As being part of that team, I can point out an outstanding performance and diligent team management skills shown by Dmytro. Facing lots of tasks and reported issues each day, Dmotry managed to bring a support effort to the next level. There were no any failures or SLA breaches. Tasks prioritization and resolution processes have been built in a very efficient way. Having multiple troubleshooting and deep investigation session conducted with the clients each day, Dmytro always shared his expertise and technical knowledge with the team, conducted multiple experience exchange sessions, was always opened to assist and deliver better results. Those were good times and I always put Dmytro as a level mark, a template for each team lead I was working in future companies.”

“Dmytro was conducting a Java/Big Data bootcamp course at a time I joined a company. He is very reasonable teacher and a good mentor who onboarded me on one of the critical projects within a company. Later we’ve been working together on that same project and I recommend Dmytro as a very senior Big Data engineer, a pleasant coworker, and a good manager who achieves business goals in time. ”

“I worked with Dmytro in Ukrainian company which is now called IT Integrator (https://it-integrator.ua/en/) from 2011 till 2013. We worked in one team on a number of projects related to network engineering. This involved designing network solutions, implementing them, auditing customer's network environments and providing recommendations to customers how to optimise their network infrastructure to get optimal performance and meet other criteria. Dmytro has strong technical skills and "can-do" attitude when it comes to finding a solution to a challenging technical problems. He regularly dedicates time to learn new things and has a continues motivation to improve and grow. I enjoyed working with Dmytro on common projects since he is easy to collaborate with, have smart ideas how to approach a technical task and successfully meets project completion deadlines even when he needs to work multiple projects at the same time. I would recommend Dmytro as an individual contributor or team lead and I think he would be an asset to any team.”
