• Guided company projects through development

  Guided the execution of numerous company projects, offering expert support in the software development phases.

• Overhauled internal processes, saving 8,000 hours

  Overhauled internal processes, saving 8,000 hours by improving software architecture, systems, and scheduling efficiency.

• Streamlined CI/CD processes, saving 4,000 hours

  Streamlined CI/CD processes, saving 4,000 hours by introducing automation in software development pipelines.

• Set a zero‑warnings bar across six languages

  Set a zero‑warnings quality bar across six languages — Go, TypeScript, SQL, Python, Shell and Markdown — enforced by pre‑commit hooks.

• Set the platform's founding technical decisions

  Set the platform's founding decisions in the weeks after the repository opened in November 2025 — the layering, database‑first data access and the zero‑warnings bar — and they still hold nine months on.

• Delivered analysis and regular progress reports

  Delivered analysis and regular progress reports to the CEO, translating engineering KPIs and delivery status into decisions.

• Built a test suite across Go, SQL and browser

  Built a layered automated test suite — 981 Go tests, 543 frontend and browser specs, 494 SQL behavioural tests — with mutation testing, property‑based tests and an accessibility gate.

• Built a 268‑check guard engine for the repo

  Built the repository's guard engine — 268 registered commit checks, 277 lint rules and 15 custom ESLint rules — plus 146 tests of the guards themselves, so the build holds the standard, not review.

• A safety net that no longer costs half an hour

  Cut the site's browser‑driven quality gate from 1,636 seconds to 615 by scheduling its checks longest‑first through a worker pool bounded to four lanes, after measuring that alphabetical order cost 320 seconds against 224.

• Ran development as 51 written initiatives

  Ran the site's development as 51 written initiatives across 54 plan documents, each carrying its open boxes, its measurements and the decisions it declined — including six of eight agent‑readiness findings refused with the reason recorded.

• Put the documentation under its own linter

  Put the documentation under its own linter — a per‑file line budget that only ratchets down, an index requirement and a real‑path check — which found six of nine plans marked done while carrying unchecked boxes, and fourteen commit‑gating tasks named in no document.

• Linted the 10,242‑line quality gate itself

  Brought 10,242 lines of quality‑gate JavaScript under a formatter and a linter after establishing it was the largest body of code in the repository and the only one nothing read, fixing 13 findings and suppressing none.

• Held the generator to 981 tests and 92% coverage

  Held the generator to 981 test cases at a 92% branch‑coverage floor with warnings treated as failures, and asserted idempotence by running the whole build pipeline twice from an empty file and requiring the second pass to change nothing.

• Enabled every linter rule as an error

  Selected every rule the Python linter has as an error, working through 1,815 findings to reach zero, with each of the few exemptions carrying a written reason and two of them backed by a checker instead of a comment.

• Wrote tests for the checkers themselves

  Wrote tests for the checkers themselves after establishing that a checker fed only clean input will one day report clean because it read nothing — planting a misspelling to confirm the spell‑check finds it, and taking an id range from the database rather than from a number in the test.

• Found the hooks and the gate disagreeing

  Found the commit hooks and the quality gate running different checks while a document promised they were the same, by comparing the two lists in a test — the five that only ever ran by hand were the ones reading the CV prose.

• Adopted Swift 6 strict concurrency over C

  Adopted Swift 6 complete strict concurrency with no actors, bridging a blocking C event loop to the main actor through one producer, one consumer and one ordering — after establishing that a task per event loses the ordering the interface depends on.

• Took the test suite to 8.9 seconds

  Took the test suite from six tests over a sixty‑second limit to 135 passing in 8.9 seconds by profiling the main thread and removing the two calls it sat inside for 3,989 samples out of 4,017.

• Held 4 repositories to one history standard

  Held four repositories to one history standard — conventional, emoji‑free, no attribution trailers, enforced by a commit‑message hook — alongside 48 instruction documents that govern how the work is done.
