I am a Senior Software Engineer with more than 10 years of experience building accessible, user-oriented web applications. My primary specialization is frontend engineering with React, JavaScript, and TypeScript.
I have delivered products across FinTech, AI multimedia, custom CRM, MedTech, EdTech, travel, and WordPress-based web development. I enjoy translating complex business workflows into reliable, responsive, and intuitive interfaces.
I have strong experience leading frontend development, designing APIs, building reusable component libraries, and modernizing legacy applications. I work effectively across the full product lifecycle, including UI/UX implementation, backend integrations, validation, error handling, and performance improvements.
Accessibility, responsive design, design systems, theming, and maintainable frontend architecture are key areas of focus in my work. I have built white-label branding systems, accessible light and dark themes, SVG-driven experiences, and shared UI foundations used across multiple products.
I work with modern JavaScript and TypeScript ecosystems including React, Next.js, Angular, Node.js, and related testing and deployment tooling. I also use AI-assisted development tools such as Claude Code, Claude Design, GitHub Copilot, and CodeRabbit to improve development quality and efficiency.
