At Kapptu, I lead the development of high-performance B2B web applications and custom infrastructure solutions. My primary focus is engineering scalable, secure, and blazing-fast digital products from scratch, moving away from bloated legacy CMS platforms. Key Responsibilities & Achievements: Architected and developed custom frontend interfaces using Next.js, React 19, and Tailwind CSS. Implemented robust server-side logic and strict data validation using TypeScript and Zod. Managed and deployed dedicated infrastructure using Docker and Nginx on private VPS environments, guaranteeing server-level security. Consistently achieved perfect Google Core Web Vitals scores by optimizing code and implementing Server-Side Rendering (SSR). Built fluid, non-blocking UI animations with GSAP to ensure a premium user experience without sacrificing performance.
