Employer

Cleversafe, Inc.
- Position: "Technical Lead / Development Manager" As an initial employee, I've worked as a team leader with the core development staff implementing the company's dispersed storage product. I currently act as engineering leader within the Advanced Technology Group, with a focus on long-term research and innovation for dispersed storage technologies, fortification of intellectual property holdings, and continuing development of the Open Source product and community.
- Company: Cleversafe Dispersed Storage software uses information dispersal (channel coding) to store small slices of data in multiple, disparate locations. Each slice contains too little information to be usable by itself, which ensures that all data stored or transmitted to the network is secure and private. Although each slice is individually unusable, any majority of the slices can be used to perfectly recreate all of the original data. As a result, the storage system remains fully usable even in the face of byzantine node failure.
