About Me

Making sure our AI/ML models are connected with our FE apps. Everything from BE (servers, DBs, containers, etc.) to CI/CD and other DevOps, from architecture to development. Passionate about making everything secure.

Rust language and networking have a special place in my heart.

In Blindspot my main focus is on developing backend services. I cooperate with frontend teams to design and implement APIs and secure them, but also with AI/ML teams to connect backend service to their models.
