Projects

SR OS

Contributed to the development of Nokia’s industry-leading Service Router Operating System (SR OS), a cornerstone of carrier-grade networking. I was responsible for the configuration management of Access Control Lists (ACLs) and Software-Defined Networking (SDN).

Additionally, I helped develop the transactional database for the configuration management system to ensure full compliance with NETCONF requirements. This involved implementing complex logic to support atomic operations and data consistency.

C8 Corvette Convertible

Part of the engineering team responsible for the Chevrolet C8 Corvette’s convertible roof controller. I specialized in building AUTOSAR-based software modules designed for maximum reliability and hardware abstraction.

Auxiliary Heater

Developed the core hardware abstraction layer (HAL) for a commercial truck auxiliary heating system. This work focused on creating a clean API for hardware-dependent features.

Wallbox

Developed a custom Linux-based operating system for a new generation of EV Wallboxes. I was responsible for the implementation of the Open Charge Point Protocol (OCPP) and all NFC-related features.

SDV Platform

I worked on the core team building out Ford’s next-generation Software-Defined Vehicle (SDV) platform. My main focus was transitioning traditional vehicle functions into a Service-Oriented Architecture (SOA), where I designed the service APIs and implemented the underlying services.
