I'm building a multi-tenant SaaS product for hospitality teams at Treema, covering guest communication, task management, and internal knowledge.
I built the backend foundation, defined shared API contracts across backend, web, and mobile clients, and designed role-based authorization, Meta and Telegram messaging infrastructure, realtime functionality, and secure AWS S3 file storage.
Previously, I developed security-management frontend applications at Kaspersky and B2B SaaS features and REST APIs at Symplete. I stay hands-on from early architecture decisions through production delivery across TypeScript, Node.js, React, and React Native.
