About me

I’m Diogo Gonçalves, a software engineer and private investor based in Lisbon.

For the past decade, I have worked in software development, building and maintaining systems where clarity, reliability, and good judgment matter. Alongside that work, I have developed a deep interest in investing, business analysis, and the process through which companies create value over long periods.

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.

Writing

I created this website to think more clearly in public.

Writing forces me to move beyond the feeling that I understand something. It requires me to define the central claim, organise the evidence, consider alternative explanations, and identify what remains uncertain.

The essays published here will generally cover:

  • Business and investment analysis
  • Competitive advantages and industry structures
  • Capital allocation and long-term value creation
  • Software engineering and system design
  • Tools connecting research, data, and decision-making
  • Lessons from building practical projects

Some articles will be detailed company analyses. Others will be shorter research notes prompted by a company result, an industry development, a technical problem, or a change in my thinking.

I do not intend to publish according to an artificial schedule. I would rather publish when I have something useful and sufficiently developed to say.

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.
