An engineer with over a decade of experience building automated test platforms for connectivity modules and IoT products. After years of working inside established product environments, I recently started DeepSpan as a working space to explore ideas more independently.
DeepSpan is used to move ideas from vague questions into concrete, usable products. The focus is on deliberate exploration and testing, documenting what works and what doesn’t, and only keeping ideas that mature through real use.
