MY PORTFOLIO
I am a citizen of Ukraine, and I have higher education, having graduated from the Higher Technical University (VNTU). My degree is as a specialist in computer systems and networks.
After graduating from university, I worked briefly as a system administrator. In parallel, I specialized in the development of hardware and software on the Arduino platform, focusing on automatic control systems for restaurant equipment.
However, I wanted more creative freedom and was attracted to the idea of working remotely from anywhere in the world. I started to take an interest in web development, and during my studies, I created my first 2 Internet projects - an information site from which I began to earn some money (Google AdSense), and the second was my first online store. To promote my own projects, in addition to web development, I began to study related areas such as SEO, SMM, copywriting, E-commerce, and fundamental business concepts.
As a developer, I chose the Front-end development area. I started working as a freelancer. I had several customers concurrently on platforms such as Freelancehunt, Upwork, Freelancer, etc. My experience in related fields helped me keep one client for a long time. I offered him, in addition to creating a site from scratch, services like SEO-promoting it, SMM, and filling the site with articles. Later, I delegated the work of SMM and copywriting to my partners, who specialized in this.
Over the past few years, I have become more interested in web development and have moved away from the concept of freelancing. Instead, I switched to full-time remote work in companies that serve clients from the USA, ES, DE, LT, and PL. My experience goes beyond web development as I am continuously improving my skills in SEO, SMM, and E-commerce. I approach each project comprehensively, prioritizing important aspects such as attractive modern design, UX/UI, technical optimization, SEO, adaptability, and security. This way, I provide the client with a fully functional product that can increase conversion.
