​

• These are my recent software/firmware projects.
• I designed, created and developed most of them; some with help from the team and some serve as proof-of-concepts to guide the team
• My broad and deep experience allows me to develop or contribute to any layer: Product, OS, App, baremetal, network, web and database in a very short time.
