What I'm looking for

I seek backend-focused roles where I can design secure, scalable architectures, lead engineering efforts, mentor teams, and apply data-driven decisions in a collaborative, growth-oriented company.

I am a backend engineer focused on building scalable, high-performance systems using NestJS, Node.js, and Rust, with strong emphasis on security and clean architecture.

I co-founded a software agency and have led backend development across startups and production environments, designing multi-tenant systems, microservices with Docker and NGINX, and data pipelines with role-based filtering.

I am currently pursuing a Master’s in Data Science, contribute as a freelancer, and mentor teams while continuously adopting modern tools for observability, deployment, and system reliability.
