[Streamlined CI/CD processes, saving 4,000 hours by introducing automation in software development pipelines.](https://engineer.company/portfolio/streamlined-ci-cd-processes-saving-4-000-hours-42/) - [Set a zero‑warnings quality bar across six languages — Go, TypeScript, SQL, Python, Shell and Markdown — enforced by pre‑commit hooks.](https://engineer.company/portfolio/set-a-zero-warnings-quality-bar-across-six-79/) - [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.](https://engineer.company/portfolio/set-the-platform-s-founding-decisions-in-november-2025-80/) - [Delivered analysis and regular progress reports to the CEO, translating engineering metrics and delivery status into decisions.](https://engineer.company/portfolio/delivered-analysis-and-regular-progress-reports-to-the-81/) - [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.](https://engineer.company/portfolio/built-a-layered-automated-test-suite-across-four-layers-94/) - [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.](https://engineer.company/portfolio/built-the-repository-s-guard-engine-of-268-checks-95/) - [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.](https://engineer.company/portfolio/cut-the-visual-quality-gate-to-ten-minutes-128/) - [Ran the site's development as 49 written initiatives across 52 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.](https://engineer.company/portfolio/ran-development-as-49-written-initiatives-141/) - [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.](https://engineer.company/portfolio/put-the-documentation-under-its-own-linter-142/) - [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.](https://engineer.company/portfolio/brought-the-quality-gate-code-under-a-linter-143/) - [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.](https://engineer.company/portfolio/held-the-generator-to-964-tests-and-a-coverage-floor-145/) - [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.](https://engineer.company/portfolio/enabled-every-python-linter-rule-as-an-error-147/) - [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.](https://engineer.company/portfolio/wrote-tests-for-the-checkers-themselves-149/) - [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.](https://engineer.company/portfolio/found-the-commit-hooks-and-the-gate-disagreeing-150/) - [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.](https://engineer.company/portfolio/adopted-swift-6-strict-concurrency-over-a-c-event-loop-156/) - [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.](https://engineer.company/portfolio/took-the-test-suite-under-nine-seconds-158/) - [Held four repositories to one history standard — conventional, emoji‑free, no attribution trailers, enforced by a commit‑message hook — alongside 46 instruction documents that govern how the work is done.](https://engineer.company/portfolio/held-five-repositories-to-one-history-standard-165/)
