What I'm looking for

I'm available for remote work, relocation, and international assignments. I’m interested in engineering leadership and technical delivery work spanning architecture, implementation, and production support.

At WiseHome, I co-founded the company and lead architecture and technical delivery across backend and cloud services, web and mobile applications, connected devices, and field operations. I created the WiseON framework architecture for shared device concepts, command and state exchange, automation rules, and integration between local control and remote services.

I combine architectural work with hands-on implementation, including production firmware in C, cryptographic mechanisms, and a proprietary communication protocol. I’ve also implemented CI/CD pipelines, led AI-assisted development adoption across a 10-person team, and investigated production reliability issues with engineering partners including Espressif.
