IMU-Based Handwriting Capture Ring

R&D · Hardware Project

Prototyped a wearable smart-ring concept for capturing handwriting from finger motion — evaluated IMU sensor options, motion-to-stroke reconstruction, and the tradeoffs between onboard processing and streaming raw data to a host device.

Board-Level Repair & Diagnostics Bench

Electronics Repair Practice

Built out a board-level repair workflow for SMD/BGA rework — selected a stereo microscope by comparing working distance and magnification tradeoffs, and established a diagnostic process for component-level fault isolation.

Collapsible Modular Whiteboard

Product / Hardware Design

Designed a modular, collapsible whiteboard system from raw materials — mechanical hinge and panel design, material selection, and assembly, worked through as a physical engineering problem rather than a software one.

Self-Hosted AI Infrastructure Platform

Internal · Ongoing

Designed and deployed a containerized AI stack — LibreChat on Docker under WSL2, MongoDB for persistence, OpenRouter as a pluggable model backend. Resolved config-loading and container restart-loop failures to get the environment production-stable.

Multi-Tenant Server Hosting Environment

Client: Small Business Hosting Venture

Evaluated and architected infrastructure for a server-hosting offering — comparing business-grade vs. residential ISP tiers, sizing bandwidth and uptime requirements, and mapping monetization paths across game server hosting and managed hosting resale.

Connectivity & Failover Diagnostics

Client: Rural Site Deployment

Diagnosed and resolved network performance issues across peering routes and DNS resolution, and evaluated Starlink and 5G hotspot hardware as primary/backup links for a low-infrastructure, mountainous deployment site.
