01 // RECONNAISSANCE
The Conflict.
"Legacy hardware clocks are expensive to deploy on temporary job sites, and standard manual entry apps are highly susceptible to fraud."
The Technical Hurdle
"A lack of verifiable spatial data allowed field workers to clock in from home, crushing profit margins."

The Pivot Points.
Challenge High-Rise GPS Drift
Constant GPS polling drained worker phone batteries rapidly.
The Engineering Pivot
Engineered a passive background location protocol that only triggers high-accuracy polling when approaching the geofence perimeter.
Why I Iterate.
Top-tier engineering isn't about getting it right the first time—it's about building systems resilient enough to handle ground-truth realities during stress testing. My pivot points represent the transition from standard implementation to elite problem solving.
