About this gig

Professional Android Engineering for Mission-Critical Hardware and Data Systems.


Most Android developers build simple UI wrappers. I build industrial-grade ecosystems.


With a background in IIoT architecture and high-stakes Fintech, I specialize in Android applications that need to talk to hardware, maintain 100% uptime, and handle secure data.


What sets my service apart?

  • Hardware & IIoT Integration: Expert-level communication via Modbus TCP, RS-232, and PLC systems.
  • Complex Architecture: Experience with dual-app systems using Android IPC (Binder/Broadcasts) to decouple UI from hardware control.
  • Security First: Implementation of Android Keystore, HMAC-SHA256, and secure payment API integrations.
  • Industrial Reliability: I build offline-first telemetry systems that ensure data integrity even in poor connectivity environments.
  • Performance: Background services optimized for 24/7 operation without system crashes or memory leaks.


Technical Stack:

  • Languages: Kotlin, Python
  • Inter-Process Communication: Binder, AIDL, Broadcast Receivers
  • Hardware: PLC, Sensors, RS-232
  • Security: Cryptographic operations, JWT, OAuth, Keystore
  • Data: Local SQL persistence with automated Cloud Sync
