Impact Case Study: SMETA Audit

The Challenge

The company risked losing international export licenses due to untraceable manual attendance records. Audits required 100% data integrity.

The Engineering Solution

I engineered a tamper-proof Python module that cross-referenced biometric logs with labor laws. Result: Passed SMETA audits 2 years in a row.

  • High-Concurrency Ingestion: Implemented Redis locking to handle "thundering herd" traffic from thousands of devices during shift changes.
  • Async Processing: Decoupled biometric hardware communication from the main API thread using Celery.
  • Shift & Attendance Engine: Replaced legacy spaghetti code with clean, decoupled models for Rotative Shifts and Suspensions.

Industrial IoT Feeding System

Python Modbus TCP Siemens S7 Django

A centralized control system connecting web infrastructure to physical field actuators. Automates shrimp feeding cycles and monitors critical water parameters via direct PLC communication.

  • Protocol Engineering: Implemented low-level Bytearray manipulation to communicate with Siemens LOGO! PLCs via Snap7 and Modbus.
  • Hardware Bridge: Built the software layer that translates API requests into physical actions (turning feeders on/off).
