📝Some clients’ feedback:
"Great developer, perfect communication and a general professional approach."
"Excellent work! Serhii is very communicative and reliable. He goes the extra mile to ensure his work meets all the requirements. He delivers projects on time. I would definitely like to work with him again. Thanks Serhii!"
"From this Project, i have the highest regard for Serhii. He is PROFESSIONAL, DELIGENT, HAS INTEGRITY & SUBJECT MATTER EXPERTISE AND IS PROFEICENT IN CODING. He takes the time to understand the Project in detail and attends to all feedback. In addition, what has set him apart from many others is that despite various challenges, he is always willing to help and sees the Project through to a successful completion. I have enjoyed working with Serhii on this Project and look forward to working with him on many more."
"Really good freelancer with skills and insight to help me with minor and major business decisions. E.g. he helped me to figure out our customer base attrition, post codes of the ideal customers etc.. for our service industry business. Impact was that we save roughly 4-5k€ /month as I now have facts to cut down Google Ads campaigns for post codes that do not produce recurring revenue.. Now I have validated data / ideas besides basic CPA to actually know that the marketing truly has a high ROI. Will definitely hire again when I have business data questions etc. All the best for this guy... Hope that he will get great work gigs in the future as well and I am sure that he will."
I am eager to engage in compelling projects involving ML and business process analysis.
