What I work on
Three threads, one habit: make it reliable.
Products
Small, well-made apps with a native feel, honest pricing, and data that stays on your device.
Data
Years of turning messy data into decisions: warehouses, dashboards, and the occasional machine-learning model.
Writing
Notes are on the way
Short posts on systems, building apps, and things I learn along the way. The first ones are in the oven.
