- Built cell localization for shipped robotic work cells, restoring arm-to-cell calibration after transport to 0.01 mm / 0.1Β° accuracy
- Containerized the cell's web HMI (Docker, Bash) so PR test deployments bring up the bin-picking app and HMI together
- Fixed calibration progress reporting in the HMI by weighting progress by per-task step counts
- Shipped Leanpub's first native iOS app in 7 weeks as one of two engineers: 105 screens, SwiftUI over GraphQL, 1,000+ downloads
- Built real-time collaborative editing across web and iOS with CRDTs (Yjs) over Rails ActionCable, porting Yjs's binary sync protocol to Swift
- Built an AI catalog assistant for leanpub.com, powered by a tool-calling LLM pipeline over the live catalog
- Built the ground control station in C++ / Qt, rendering 100+ Hz telemetry with live 3D attitude and a satellite-view map
- Designed non-blocking STM32 firmware (SPI) delivering a jitter-free 1 kHz IMU pipeline
- Built a bidirectional radio link with COBS framing and Protobuf, plus the PID flight-control law and a CTest regression harness
A real-time trade tape on a DE10-Lite FPGA.
Tech: SystemVerilog, Python, UART
- Python bridge streams live Coinbase trades as binary frames over UART to a SystemVerilog parser FSM
- Resynchronizing parser with length + XOR checksum validation, sequence-gap detection, and byte timeouts, verified in testbenches before hardware bring-up
πͺ GravitySandbox 3D
Interactive N-body gravity simulator in the browser, rewritten from a 2D Qt/C++ prototype.
Tech: TypeScript, React, three.js, Vitest
- Leapfrog KDK integrator with Plummer softening and momentum-conserving merges, in astronomical units (G = 4ΟΒ²)
- Allocation-free 60 Hz frame loop that never re-renders React; Vitest suite covers 160-year orbit stability and energy drift
π₯οΈ ivanluo.xyz (source)
A personal site rendered onto a 3D Macintosh you can orbit and zoom into.
Tech: JavaScript, three.js
- Profile-driven desktop engine with windows, apps, and a read-only terminal over a virtual filesystem
ποΈ Whistler Blackcomb Forecast
Mountain-specific forecast app that corrects generic weather models using Whistler's local forecast errors.
Tech: Python, FastAPI, PostgreSQL, LightGBM, Next.js, Docker
- Trained LightGBM correction models on archived GFS forecasts vs. ECCC / Open-Meteo observations going back to 2022
- Forecasts alpine snowfall, wind, freezing level, and precip type across base / mid / alpine bands, with SMS alerts via Twilio
π£ CS2 Nade Guide
Native iPhone app for saving and sharing CS2 grenade lineups and tactics.
Tech: SwiftUI, SwiftData + CloudKit, Supabase
- Local-first library synced through CloudKit, with a thin backend only for sign-in and shared tactics
