During my internship at XenKrypt Technologies, I contributed to both the public web platform and Encrypti-V, a privacy-first communication suite. I designed and developed the Next.js-based corporate website, integrating interactive 3D experiences with Three.js and optimizing rendering strategies to improve Lighthouse scores and maintain SEO-friendly server-side rendering.
For Encrypti-V, I architected the PostgreSQL schema, REST APIs, and Node.js backend to support scalable, encrypted communication. I implemented zero-knowledge, client-side encrypted file sharing using AES-256-GCM and post-quantum ML-KEM algorithms, utilizing chunked processing to ensure secure, memory-efficient large file uploads directly in the browser.
