Hey, friend!
Glad to see you at my CV website! I hope you like it and you will find something interesting for you.
So, who am I? My name is Serhii Avdieiev and I am a Lead Frontend Engineer with more than 20 years of experience building high-performance, scalable web applications within the fintech, e-commerce, and media sectors. Throughout my career, I have balanced deep technical execution with architectural ownership and team leadership to deliver resilient and maintainable frontend systems. In my most recent leadership roles, I have been responsible for defining frontend architecture and establishing the engineering standards that guide complex web platforms. My core expertise lies in React, Angular, TypeScript, and Node.js, with a heavy focus on scalability and performance optimization. I have spearheaded major refactoring initiatives to eliminate technical debt and implemented strategies like code splitting and lazy loading to ensure high-speed user experiences. I believe that consistent code quality is achieved through structured review processes and rigorous testing practices. Beyond the code, I prioritize the growth of the engineering team and the clarity of the product roadmap. I actively mentor developers, facilitate architectural discussions, and ensure that technical decisions are always aligned with broader business objectives. By collaborating closely with product managers, designers, and backend engineers, I translate complex requirements into practical solutions. I am particularly skilled at communicating technical trade-offs to non-technical stakeholders, ensuring that delivery timelines are both realistic and sustainable. What distinguishes my approach as a Lead is the ability to think beyond individual features and toward the health of the entire ecosystem. I focus on building sustainable systems and improving engineering culture, which enables teams to deliver efficiently at scale. I take full ownership of technical decisions, always considering their long-term impact on product stability and development velocity.I am consistently motivated by challenging environments where architecture, performance, and collaboration are treated as priorities. I thrive in roles that require a blend of hands-on technical mastery and high-level strategic thinking to drive real product value.
