About me

I am a Senior Front-End Developer with over 8 years of experience specializing in building scalable and high-performance web applications. Throughout my career, I have worked extensively with modern JavaScript frameworks such as React and Next.js, leveraging TypeScript to create robust and maintainable codebases. I am passionate about improving user experience by optimizing performance and implementing best practices in testing and architecture.

In my recent role at FlexMade, I designed and implemented the core architecture for two large-scale projects, leading to an early release ahead of schedule. I played a key role in developing advertising features that helped the startup become profitable within its first year. I also led a migration to Next.js v14, which significantly improved the Time to Interactive metric.

I have strong experience integrating analytics platforms like Snowplow, Parse.ly, and Google Analytics to track user behavior and increase newsletter subscriptions. I am committed to quality, having expanded test coverage to over 80% and reducing QA cycle times substantially. Additionally, I implemented a design token system that standardized UI elements and cut design QA time by nearly half.

Previously, at TGA Digital, I delivered mission-critical projects ahead of schedule during challenging times and mentored junior developers while conducting technical interviews. I also implemented localization for multiple languages, increasing traffic and improving validation processes to reduce change request times.

At Akvelon Inc, I rewrote entire projects to improve load times and reduce bugs, resolved numerous critical production errors, and boosted page speed through lazy loading and Azure cloud integration. I am proficient in a wide range of technologies and tools, including React, Redux, Apollo, Jest, Docker, and cloud services, and I follow agile methodologies such as Scrum and Kanban.

I am fluent in English and Russian and enjoy collaborating with cross-functional teams to deliver high-quality software solutions. I am always eager to learn new technologies and contribute to innovative projects that make a real impact.
