⭐ Chris Mendoza — Android (Kotlin/Compose) & Python Automation Developer
Hi, I’m Chris, a developer who loves turning complex engineering workflows into clean, reliable software.
My focus is Android development with Kotlin + Jetpack Compose and Python automation—especially tools that make real-world processes work smoother, from mobile UI features to OCR pipelines and system utilities.
I enjoy solving problems that mix structure, precision, and creativity.
If something needs to be debugged, refactored, automated, or rebuilt cleanly… that’s my wheelhouse.
- Kotlin
- Jetpack Compose
- Android SDK
- MVVM architecture
- Coroutines

Android app for generating marine shaft schematics using parametric components and real-world machining rules.
Key features:
- Jetpack Compose UI
- Parametric bodies, tapers, liners, bearings
- Live dimensioning and snapping
- Taper calculations & metadata validation
- PDF export and drawing layout engine
- Clean, modular architecture
Designed to support real machining workflows with precision, clarity, and repeatable results.

A lightweight, local-first USB backup utility focused on reliability, transparency, and zero-surprise behavior.
Key features:
- One-shot and scheduled backup execution
- JSON-based configuration for clarity and auditability
- Safe, deterministic file syncing (robocopy-based)
- Designed for removable drives and offline workflows
- Clean CLI output and predictable behavior
Built as a practical automation tool with a strong emphasis on correctness, debuggability, and user trust.

- Android features, UI updates, and bug fixes
- Kotlin + Compose modernization
- Python tooling, data extraction, OCR pipelines
- FastAPI microservices and backend automations
- Refactoring legacy codebases into maintainable systems
- Debugging complex issues and designing clean resolutions
I focus on:
- Clear communication
- Thoughtful, predictable engineering
