Keicho Payroll
Business Problem

Field service companies suffered from inaccurate paper timesheets, buddy-punching fraud, and supervisor difficulty estimating labor and overtime costs before dispatching teams to remote project sites.

Technical Approach

Designed a dual-app architecture with selfie and geofence-gated clock-in/out, backed by a Node.js suggestion engine that analyzes wage rates, physical distance, and scheduled overtime in real time.

Business & Product Value

Eliminated time-theft with biometric and GPS verification, reduced supervisor scheduling friction, and gave management proactive visibility into project payroll costs before work begins.

Product Architecture

Keicho is an enterprise workforce management and job-scheduling platform. It features specialized Worker and Supervisor mobile experiences that centralize field operations, automated travel-cost calculation, and fraud-resistant attendance.

Key Engineering Deliverables

01

Location & Selfie-Verified Clock-In

Guaranteed timesheet integrity by requiring real-time selfies validated against site GPS boundaries, providing supervisors verified photo timestamps and immediate fraud alerts.

02

Smart Cost & Route Suggestion Engine

Constructed an intelligent dispatcher algorithm that calculates estimated project costs prior to worker assignment by cross-referencing base pay, overtime tiers, and travel distance.

03

Dynamic Multi-Shift Reassignment

Enabled supervisors to intercept, adjust, and reassign field workers dynamically across multiple job sites mid-shift in response to weather conditions or urgent project demands.
