Continuous glucose monitor reading: 97 milligrams per decilitre, 1 min ago. Over the last 24 hours, 89 percent of readings were inside the target range of 70 to 180, with an average of 126.

I write software that ships.

I have spent 17 years building software: networks and telecom first, then products. I am the Founding AI Engineer at Lighthouse Legal, working with founder Ravi Jayanthi. I also co-founded Nextvisit AI. I publish Laravel and PHP packages, LLM tools, and datasets.

The chart behind this text shows my blood glucose, live from my own Nightscout server. I have had Type 1 diabetes since 2023. An open-source loop doses my insulin, and I read its output the same way I read any other production system. My current insulin and carbs on board are just below.

On board

IOB · COB · 24 h

Glucose is the output. Loop tracks two inputs: insulin still acting and carbohydrates still absorbing. The gauges show the current values. The plot shows the last 24 hours, with insulin below the midline and carbs above it. Glucose runs underneath both. Most hours, there is nothing above the line.

Loop on-board: 0.23 units of insulin still acting, 0 grams of carbohydrate still absorbing, sensor glucose 97 milligrams per decilitre, just now. The plot under the gauges is twenty-four hours of those remaining quantities. Insulin is below the midline; carbs are above it; the glucose they move is traced underneath.
