Hi, I'm
Jack Guillet
I build and operate platforms that serve millions of users.
About Me
I'm a software engineer with 4+ years of experience at Microsoft, where I've helped build and scale the Xbox Game Streaming platform serving 10M+ global users. My day-to-day involves Kubernetes orchestration, infrastructure-as-code with Terraform, and designing systems that are reliable, secure, and cost-efficient.
Outside of work, I'm a wing foil enthusiast, skier, and cyclist based in Seattle. I built Wing Check because I got tired of checking five different weather apps before deciding whether to hit the water — so I made one that does it all.
I'm currently looking for my next challenge at a mission-driven company building real-world products at scale.

Featured Project
Wing Check
Real-time wind forecasting for wing foil spots worldwide
A full-stack web app that aggregates weather data from multiple sources to help wing foilers find the best conditions. Features ranked forecasts, a curated database of 50+ global spots, and per-spot multi-day outlooks.
Tech Stack
Currently Building
Martin Mars Flying Boat
CAD & Planning Phase
Building a 1/20 scale model of the Martin Mars — a massive WWII-era flying boat — using a hybrid approach that combines 3D printing with traditional RC aircraft construction.
- 10-foot wingspan with 4 brushless motors and differential thrust water steering
- 3D printing ~150 parts in lightweight LW-PLA on a Prusa MK4S — hull bulkheads, wing ribs, nacelles, and tip floats
- Traditional balsa and carbon fiber for wing skins, spars, and control surfaces
- Full CAD workflow in Fusion 360, tracing profiles from original Ivan Pettigrew plans
