Software engineer building apps, electronics, robots, tools, and experiments - then sharing how they're made.
Builds
More shipped work on GitHub ↗.
Local AI coding assistant built for Apple Silicon. Runs Qwen models on-device via MLX-LM with Xcode integration and a custom CLI: no cloud, no API keys, no latency.
Key Engineering Decisions
REST API that monitors real-time room sensor data and fires automated alerts when temperature or occupancy thresholds are exceeded.

Backend API streaming live sensor data from a Raspberry Pi into a local MongoDB instance with real-time monitoring.
An idea parking lot. I have more ideas than I can finish, so this parks and scores them instead of starting them. Active work is capped at three slots on purpose.
Key Engineering Decisions
Reverse-engineering the COLMI R09 smart ring's BLE protocol in Swift. Pulling heart rate, SpO2, sleep, and step data natively without the vendor app.
Custom RC car firmware written in C++ with ESP32 control, FPV camera feed, and live telemetry logging. Documenting the complete build from schematic to track.
Downloadable source-code packs, wiring schematics, and video walkthroughs. Practical builds and tools with full implementation code available.
Apps
Native iOS vehicle maintenance tracker. Service logs, fuel tracking, NHTSA recalls, iCloud sync, Apple Intelligence.
Beauty & self-care ritual app. Routines, cycle tracking, progress photos, budget. All on-device, no account required.
Track bills in a simple way. Recurring expense management, schedule overviews, and clean notifications.
Full details, screenshots & links on the Apps page ↗.
Project Packs
Downloadable project packs for hardware, embedded systems, and apps. Full implementation code, parts lists, schematics, and video walkthroughs.

Low-latency FPV camera mount with gyro-based head tracking for RC vehicles. Complete firmware, 3D print files, wiring schematics, and setup guide.
About
I'm Naim Lindsay, a software engineer and builder with a B.S. in Computer Science. I build native iOS apps with Swift and SwiftUI, cross-platform mobile apps with Flutter & Dart, design embedded systems and electronics, and back it all up with Python and Go on the server side. I got my start shipping real apps solo - from breadboards and firmware to live App Store products.
I go deep across the stack: native Swift for Apple platforms, Flutter & Dart for fast, responsive cross-platform mobile experiences (including upcoming releases like Modern Bills), custom C++ firmware for microcontrollers, and Python or Go wherever the backend needs real engineering.
