Vadim K.

Senior Front-End / Full Stack Engineer specializing in React, TypeScript, modern UI architecture, and legacy modernization. I help companies modernize and scale web applications without risky full rewrites. Over the past 10+ years, I’ve worked on enterprise SaaS platforms, CRM systems, custom web applications, and high-traffic business websites using React, TypeScript, JavaScript, Node.js, PHP, WordPress, and modern front-end tooling. My background combines strong engineering with design awareness — I care not only about clean architecture and maintainable code, but also about usability, accessibility, responsiveness, and polished UI/UX. What I can help with: • React / Node.js applications • Front-end architecture and modernization • Legacy migration (jQuery → React / modern stack) • TypeScript and scalable component systems • Responsive UI development • Accessibility (WCAG / 508) • WordPress development and customization • API integrations • Performance optimization • AI-assisted development workflows • UI implementation from Figma designs I’m comfortable collaborating directly with product, design, QA, and backend teams, and I enjoy solving complex technical problems while keeping the user experience clean and intuitive. I focus on writing maintainable, scalable code and building products that teams can confidently grow long-term.
