Proof of origin

Every engineer has a starting point. Mine was a proof, not a product — so here it is, written the way I learned to think. From an Applied Mathematics axiom to a software engineer, Q.E.D.

theorem · origin

Claim

∃ a path P such that P : PureMathematics ⟶ Software

Proof.

  1. 1
    2018let foundation ={ calculus, linear_algebra, differential_eq }

    // enrolled · pure abstraction, no code yet

  2. 2
    2020foundation.map(abstraction ⟼ execution)

    // 3rd year · two CS courses — first contact

  3. 3
    2021solve(mathProblems, "C++") ⟹ a proof that runs

    // 4th year · the fixed point where it all converged

  4. 4
    2022∴ return SoftwareEngineer

    // graduated · Q.E.D.
