CryptoNext Security
Senior Fullstack Software Engineer 2026 - present
Hello World!
My name is Valère
Senior Fullstack TypeScript Engineer
I’m a Senior Fullstack Software Engineer at CryptoNext Security , where I work on post-quantum cryptography migration and high-volume asset monitoring. Over the last 10+ years I’ve taken platforms from architecture to production across EDR cybersecurity, nationwide healthcare reporting, and post-quantum cryptography. I’m passionate about modern web technologies, distributed systems, and developer tooling. I focus on building scalable TypeScript applications, type-safe APIs, and AI-assisted engineering workflows, including DailyBriefs, an AI-powered news briefing side project live in production.
