Invest & Build

Practical essays on investing and software, focused on clear, robust, long‑term systems.

A sleek, minimalist wooden desk holds an open ultrawide monitor displaying a clean dashboard of investment charts on one side and neatly formatted code on the other. A dark metal laptop rests beside a graphite notebook with a mechanical pencil precisely aligned on top. The desk sits near a large window overlooking a soft-focus modern cityscape. Cool daylight pours in, creating crisp reflections on the monitor and subtle shadows along the grain of the wood. Photographic realism, shot at eye level with a shallow depth of field, emphasizes the workspace as focused and professional, blending finance and software in a calm, high-level atmosphere that suits a thoughtful personal site about investing and technology.
A close-up of a dark, brushed-metal mechanical keyboard with subtle white backlighting, positioned on a matte black desk next to a slim, silver laptop running clean, readable code. Beside them lies a neatly stacked set of printed pages featuring structured investment notes and a tidy column of numbers highlighted in pale blue. Soft, diffused afternoon light from an unseen window creates gentle gradients across the metal surfaces and a faint reflection on the laptop trackpad. Photographic realism, captured from a slightly elevated angle with selective focus on the keys, conveys a disciplined, analytical mood, merging the precision of programming with the structure of long-term investing in a modern, professional aesthetic.

About

I’m Diogo. I combine software engineering and long-term investing to build clear, simple, and robust systems, products, and portfolios.

A large, high-resolution monitor displays a minimalist line chart of a long-term investment portfolio, with smooth, upward-trending lines in muted blues and greens against a clean white background. The monitor rests on a light oak desk beside a compact, dark grey desktop computer and a small, open notebook filled with sketched system diagrams. In the background, a whiteboard on the wall shows faint, out-of-focus architecture diagrams and arrows. Neutral daylight from the side washes the scene in soft, even light, with subtle shadows giving depth. Photographic realism, shot from a three-quarter angle with medium depth of field, creates a calm, strategic atmosphere focused on high-level thinking and structured decision-making.

Projects

I work on selective projects: software development, investment automation, fundamental research, and systems that connect code, data, and better decisions.
