    I've been in the IT industry for over 7 years now, developing projects with different levels of complexity, budget range and timeline. I used to work in a team of developers with Project Managers, QAs, Designers, Business Analysts and Product Owners to deliver high-level products. I find 2 years freelance work to be an indisputable advantage. Thanks to that experience I have empowered such skills as communication with clients, finding solutions to the problem with any level of complexity, getting deeper to the client’s business goals, and consulting clients to find the most appropriate solution. I sincerely believe that our cooperation and mutual passion will lead us to the highest results.⭐️ Let’s work together to deliver superlative products!

    Brief highlights: ☑️ Graduate Software Engineer ☑️ 8 years of experience ☑️ 32 projects on Symfony and Magento ☑️ Business-oriented development ideology follower. Kyrylo is here, In two sentences I'll tell you if I can help you. If you are a business owner with or without technology expertise who needs a geek part-time to speed up his business with business-oriented development, I can help you. In my work, I believe in close cooperation and mutual interest. The difference between a developer/coder and a software engineer is understanding of business goals, the engineer takes responsibility for resolving business goals, not just developing features. Speaking of my strength: – 38 of 41 projects delivered in time – 29 of 31 clients fully satisfied with the result – Avg. cooperation time with clients is more than 3 months. I believe it's better to explain myself in numbers instead of empty words like "deliver in time", "best customer service" etc. One of my latest projects that represents my skills is an application for the petrol ⛽️ company. In one year we achieved awesome goals well measured in company revenue growth. One of these achievements is an integration with the first neobank of Ukraine, it gave us 37% of credit card operations growth in 4 months. Also, we were the 4th petrol app that implemented fully contactless refuelling from the app in covid times. From this project, you can see that works not on features, but business problems and goals. Push the green button, let's discuss your project and my potential participation in it. Best, Kyrylo Romantsov
