New here?
I'm Luis Duque — a licensed bridge engineer based in Rapid City, SD. I design infrastructure by day and write about analog planning, stationery, and intentional productivity by night. This page will point you to the right place based on what brought you here.
Where do you fit?
Fountain pen reviews, notebook comparisons, EDC setups, and the philosophy of writing by hand in a digital world. Practical, specific, and opinionated.
Weekly field notes on planning systems, productivity frameworks, and the tools that actually work in a demanding professional life. Free, in your inbox every week.
Real conversations on promotion, leadership, salary, and the professional skills engineering school never covered. Peer-to-peer, not a lecture.
I'm a licensed bridge engineer (PE, M.ASCE) based in Rapid City, South Dakota. I grew up in the coffee region of Colombia — my family has farmed the same land for over 50 years. I came to the US for engineering and stayed for the work.
I started Planning Engineered because I couldn't find anyone in the stationery and analog planning space who came at it from an engineering perspective — systematic, specific, and skeptical of anything that doesn't actually work in a demanding professional life.
Every morning I pour a cup of Ríos de Oro coffee (our family import), open my notebook, and plan the day. That ritual is what this whole thing is built around.
Three good places to begin
Pen pouches, EDC setups, notebook reviews, and planning system walkthroughs — filmed on a real desk, by a real engineer.
