    Oleksandr is a talented front-end developer who has been an absolute pleasure to work with. Over the past few months, he has been tackling some front-end development, including optimizing performance, hardening and updating our codebase, upgrading from Vue 2 to Vue 3, and implementing features in Vue.js and D3.js. Our codebase is quite large, and Oleksandr quickly learned the intricacies of it. He works quickly and efficiently, adjusting his schedule to maximize overlap with our local development team. He’s clearly dedicated to his work, working hard to ensure that his code changes were thoroughly tested and quickly addressing any issues we raised. He was eager to suggest improvements based on his experience and takes feedback and direction well. He’s highly communicative and eager to make sure the solution works well for our needs. I would strongly recommend him, and I would be happy to work with him again.

    Oleksandr was very professional, quick & responsive. He took the time to ask me the questions he needed to in order to bring my vision to life. Given that my knowledge is limited when it comes to software engineering, I needed a little more patience from my developer, which Oleksandr gave to me. He took the time to explain the concepts and made sure my wishes always came first. Would hire again and recommend 10/10.
