As a seasoned Senior Software Engineer with six years of experience in digital product development using agile methodologies, I have honed exceptional technical and coding skills, strong problem-solving capabilities, and expertise in user interface design, testing, and debugging. Over the past two years, I have been a key Senior Software Engineer at GoIT Global, responsible for frontend architecture, performance optimization, driving innovation, and integrating AI solutions. One of my proudest achievements is successfully launching the GoIT LMS from scratch, which now educates over 20,000 students from Ukraine, Poland, and Romania. My contributions included developing AI-based features that reduced operational costs by 32%, designing scalable frontend architecture, creating a design system that reduced development time by 30%, optimizing core web vitals to cut average load time by 30%, and implementing feature flags that shortened the time to market for new features by 40%. Prior to my current role, I served as a Senior Software Engineer at EPAM Systems, where I led the development team for an AI-based service and developed a SPA using React, reducing load times by 40%. I also contributed to the EPAM UUI Framework, mentored junior developers, and conducted thorough code reviews to maintain high code quality. Earlier in my career, as a Software Engineer at Onseo, I played a key role in developing SPA for virginbet.com, which led to a significant increase in site performance and user engagement. I have consistently demonstrated my ability to optimize performance, maintain codebase integrity, and ensure alignment with project goals. My foundational experience includes developing and maintaining e-commerce solutions on Salesforce and Magento platforms at Astound Commerce, where I focused on writing high-quality code, performance optimization, and code review. With a strong background in both software engineering and project management, I bring a comprehensive skill set that includes advanced coding, team leadership, and effective problem-solving to every project I undertake.Tech Stack
