Client Testimonials

Andrii had some good ideas right up front that save time and resulted in a solution that worked very well. His quick understanding of my systems setup and the need to be met had a big impact on the success of the project. The solution he developed worked the first time. He followed up well and was interested in the overall success of what I was attempting.

Andrii did excellent work for me on this project. I needed code to integrate three separate computer programs in an established workflow that had not been running smoothly. His solution had a big impact. It effectively automated key steps of the workflow and made the entire process run in less time and more smoothly (big drop in number of crashes). Andrii carefully studied the current processes and made targeted suggestions. We worked through them methodically and came up with a robust solution. His work is high quality and on time. His communication skills are excellent and he always followed through meeting objectives we had agreed to. He is a pleasure to work with.

Andrei was an absolutely amazing freelancer to work with. He was super efficient, very helpful and understood exactly what I wanted (even though I struggled to explain what I wanted myself.

Andrii was great to work with. Andrii was responsive and always sought to make sure I was getting the best possible outcome. Thank you!

Andrii was amazing. He really took the time to understand the scope of the project, asked great questions, took initiative and even improved our vision. We worked with him for two jobs already and will certainly be using him again. I highly recommend him. Professional, skilled, a great communicator and able to meet deadlines.

Andrii is incredible. We’ve been working with him for a while and this is the third job he did for us successfully and exactly to our standards. I highly recommend him.

Andrii has completed several projects for me and each one has been done with the type of care I would do if I had his skills. His attention to getting the project done right is a huge benefit. He can see the big picture of what needs to be done, work through the details rigorously, and his interpersonal style and skills make the process go smoothly. Thank you, Andrii!!

Andrii always does a great job. We’ve worked with him on numerous projects and will need his services again in the future. He’s highly recommended.

I’ve worked with Andrii on multiple projects at this point and really value his skill level, adherence to details and punctual nature. He’s also a great communicator. We’ll be working with him again for sure.

About Me

My name is Andrii – Business Analyst, professional Microsoft Excel & Google Sheets Developer, PC Automation Expert, Project Manager, and Process Architect.

I am a big fan of automation and the number one enemy for any routine process. If I have to do anything twice on my PC – it gets automated.

I have been creating custom automation tools and solutions since 2010. Spreadsheets had become my lifestyle when I started working with the data. They gave me the ability to process the information quickly, make a useful analysis, and automate the whole process.

Every sphere and activity of my life has its separate Excel or Google Sheets projects. It allows me to get more value from the data, organize the thinking, make data-driven decisions and relieve my life from the routine. What is most important, it supplies me with Time – the most valuable resource. I don’t waste it.

I used to work in big international companies like Philip Morris and Samsung. Due to my skills and enthusiasm, I was known as the local Excel Guru –  I have created numerous business tools for most company departments. My automation allowed me to substitute the work of many people, the long time-consuming tasks have turned into few seconds for reliable scripts, and even the whole processes have been automated.

My contribution to each project is not limited to automation development. I am a master of analyzing and optimizing the processes, finding the most effective approaches, asking the right questions, and sharing my recommendations.

Besides the Spreadsheets Development, I am good and experienced in process management and optimization:

+ IT Project Manager of ThinkWider App (application for submitting ideas and their full processing from reviewing and discussing till implementation and rewarding).

+ Manager and Developer of IShare Educational Platform

++ I am an active top-rated Excel & Google Sheets Expert and Mentor for other experts. I solve around ten different automation cases daily, which are used by the sales staff, managers, HRs, investment agents, and others. Sometimes it seems that I worked with people from every possible sphere. I even helped the employees from the United Nations.
