Chemist-turned-developer working as Software Developer at Hess Services Inc. I build internal tools, ERP integrations, and automation systems for manufacturing environments. My day-to-day spans Python and Rust CLI tools, dashboards, AWS infrastructure, and database work across SQL Server and MySQL.
Outside work I build hobby projects for around the house. Those live at lperezmo.github.io.
Background: Dual B.S. in Chemistry & Mathematics from Linfield College, M.S. in Chemistry from the University of Oregon.

An Android app that runs an MCP server on the phone itself, so Claude can read the screen, tap, type and answer notifications from anywhere. |
A sensor on the side of the fridge that notices a burner left on with nobody around, pushes a photo to my phone, and lets Claude check on it. |
One tap prints a label with the current date and time, so everything in the fridge and freezer says when it went in or was opened. |

AG Grid tables for Streamlit. Interactive editing, filtering, sorting, and grouping, built with Custom Components v2. |
A tiny Clawd and a live dashboard for Claude Code. Watch your limits, your context and your cache without leaving the terminal. Unofficial fan mod. |
