Four habits I keep coming back to.

  1. Find the real problem first

    If the problem is vague, the product will be too. I try to put a number on it before I design anything.

    Two projects started from a number that did not add up, and putting a number on the gap is what made each one clear.

    19.2x

    more spend in the larger campaign

    73.8%

    drop in post-click approved conversion

  2. Know who it is for

    A problem only matters once I know whose it is. Every project here names its users.

    Every project page says who it is for. Writing that line first changes what gets built: Migration Guard's users need a reason for every finding, so it gives one.

  3. Measure, don't guess

    I check results against something known: an analytical answer, a planted change, a significance test.

    The growth analysis split a cost jump into three parts with no residual. Migration Guard was checked by planting real changes and counting what it found.

    98.1%

    of the cost increase happened after the click

    11 of 11

    planted changes caught in a live pass, no false positives

  4. Write down why

    Code shows what I did. A short note on why is what helps the next person, and me later.

    NitroDB has the design written before the code and a claim-by-claim check after it. AetherScan documents what it cannot do.

    3

    design documents: a blueprint before the code, a verification matrix and an interview guide after

    15

    documents in its docs folder, from the product brief to the limitations file

If any of this sounds like what you need, write to me.
