Selected Work
A selection of engagements across PCBA manufacturing, DFM review, web design, and product development. Details adjusted where NDA applies.
Led process optimization across multiple SMT lines in a high-volume production environment running 60K+ units per week. Engagement covered stencil printing parameters, SPI threshold calibration, pick-and-place program optimization, reflow profile tuning, and cross-shift workflow coordination. Improvements were implemented simultaneously across both on-site and off-site production lines.
Root-caused chronically poor solder paste printing yield on a complex mixed-component board. Redesigned stencil apertures for area ratio compliance, selected an optimized paste chemistry for the thermal profile, and tuned SPI accept/reject thresholds. Implemented a formal stencil qualification and replacement protocol.
Pre-production Gerber review for a ruggedized defense board with multiple high-density BGAs. Identified via-in-pad escape routing issues, stencil aperture area ratio failures for fine-pitch components, and thermal relief inadequacies near a large copper pour.
A full-stack web application built for a youth soccer coaching program. The platform provides coaches and players with role-based dashboards, structured training plan management, and a drill library. Built with Next.js and Supabase, deployed on Vercel with automatic CI/CD — replacing scattered PDF handouts and group chats with a single organized platform.
Features include role-based access control, auto badge award system, training plan builder, user onboarding guides, and Venmo deep link integration.
Led qualification and line-wide rollout of a new solder paste alloy to address recurring reflow oven clogging defects impacting uptime and yield. Managed compatibility testing across multiple board designs, reflow profile re-characterization, and cross-functional coordination with supply chain and production teams. Process documentation and training materials authored for full team deployment.
Developed a comprehensive X-ray inspection SOP for high-reliability PCBA assemblies. Covered image acquisition parameters, void acceptance criteria per IPC-7095, BGA cross-section interpretation, and non-conformance documentation workflow.
Full rebuild of a regional table tennis league management platform. Features ladder rankings, match result entry, badge award system, and player profiles. Built on React with Supabase backend and deployed on Vercel with automatic CI/CD.
Developed a repair and touch-up SOP for conformal coating removal and recoating on high-reliability PCBA assemblies. Covered blast media selection, masking procedures, cure verification, and IPC-CC-830 acceptance criteria.
