Attendance data is only useful if it arrives reliably, even from a biometric device on a flaky office network.

Core Architectural Overview

I architected and built the local synchronization agent that bridges physical biometric attendance devices with Zodeck's cloud-based HR platform, designed specifically to handle high-volume bursts without dropping records or overwhelming the API.

Queue-driven synchronization pipeline processing 10,000+ attendance records during burst scenarios
Intelligent buffering and payload chunking to move large datasets without API bottlenecks or timeouts
Backpressure control to regulate throughput based on live API capacity
Fault-tolerant retry mechanism with isolated job processing, so one failed record never blocks the rest
Duplicate-prevention and consistency checks between biometric devices and the cloud platform

Reliability at the Edge

A big part of this build was optimizing for the reality of on-premise hardware: unstable networks, intermittent connectivity, and devices that don't behave like clean cloud services.

Reliable delivery guarantees over low-bandwidth, intermittent connections
Windows Service / desktop agent packaging for on-site deployment
Logging and monitoring integration to simplify troubleshooting
