Accessible mobile engineering

Volunteer software engineering for Petanetra — an accessibility-oriented product that combines on-device object detection with offline, multilingual spatial guidance.

Focus

• On-device ML integration — ONNX and TFLite inside a maintainable Android architecture, not a one-off demo layer.
• Instrumentation — attribution and navigation tracking refined enough to learn where users struggle without guessing from anecdotes.
• Team coordination — informal technical leadership across mobile and platform work when the roadmap needed slicing, not just tickets.

What visitors should take away

Evidence that backend and platform instincts translate to mobile and applied ML: clear boundaries, offline constraints, and product feedback loops that respect real users’ environments.
