My actual contribution
Engineered and verified the file import application logic to process CSV, XLS, and XLSX device exports, match biometric user IDs to Odoo employee records, reconcile repeated check-in/out scans, and synchronize validated attendance entries into Odoo 16.
03
System/process involved
The integration pipeline ingests raw export files from biometric clocks, validates file headers, resolves employee identifiers, applies scan pairing rules, converts local clock timestamps to UTC, and creates attendance records in Odoo 16.
File-based import pipeline; does not connect via real-time biometric hardware streaming API.
04
Technical details that are verified
Code and regression-test review supports employee matching, approximately 3-hour duplicate-scan reconciliation, approximately 36-hour overnight pairing, and local-to-UTC conversion. These are implementation findings, not production or on-call evidence.
05
Relevant lessons or complexity
The hard part was reconciling noisy scans and cross-day shifts without duplicating attendance records. The reviewed importer includes duplicate guards and a re-read before per-row fallback after a failed batch; this is not proof of exactly-once delivery under concurrency or post-go-live support.
Initial exploration conducted through PT Arkana Solusi Digital; later import implementation phase executed through PT Naska Jala Dewa.
