# Technical Documentation > Selected work demonstrating this service. - [Designed a comprehensive infrastructure framework for DTU impacting 14 departments, featuring flexible modules, unified data pipelines, and structured support strategies for long‑term adoption.](https://engineer.company/portfolio/designed-a-comprehensive-infrastructure-framework-for-dtu-impacting-3/) - [Delivered 8 Power BI projects with comprehensive manuals, integrating Microsoft Power BI tools with NodeJS API and Python FastAPI for effective data analytics and visualization.](https://engineer.company/portfolio/delivered-8-power-bi-projects-with-comprehensive-manuals-10/) - [Wrote 50,000 words of comprehensive software documentation utilizing Markdown in GitHub, Craft, and Confluence, thereby ensuring the retention of knowledge and the transparency of the process.](https://engineer.company/portfolio/wrote-50-000-words-of-comprehensive-software-documentation-30/) - [Migrated the HTTP API from Fiber to Huma v2 — 649 paths and 760 operations — reaching and holding 100% parity between the routes the server registers and the OpenAPI description it publishes.](https://engineer.company/portfolio/migrated-the-http-api-from-fiber-to-huma-60/) - [Authored 578 go‑task automation targets spanning native, Docker and HTTPS dev modes, linting, testing, database and deployment.](https://engineer.company/portfolio/authored-578-go-task-automation-targets-70/) - [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/) - [Established a continuous security programme — code scanning, DAST, dependency and vulnerability checks, SBOM generation, secret scanning and SHA‑pinned actions — alongside 21 written security audits.](https://engineer.company/portfolio/established-a-continuous-security-programme-104/) - [Built seven read‑only reporting roles that render a live host to Markdown — facts, access, git, metrics, traffic, security and provider inventory — under a rule that no number is printed the run did not measure.](https://engineer.company/portfolio/built-seven-read-only-host-reporting-roles-120/) - [Wrote a scope rule into the repository after a restructure carried another company's inventory, firewall allowances and prose into it — and kept the quarantined residue under the secret scanner rather than excluding it.](https://engineer.company/portfolio/wrote-a-scope-rule-after-a-credential-leak-124/) - [Built a commit gate of 22 one‑line linters plus four that earn a paragraph, with no warning tier and no inline suppressions permitted, covering HTML, CSS, JavaScript, Python, YAML, Markdown, shell, links, spelling, secrets and typography.](https://engineer.company/portfolio/built-a-22-linter-commit-gate-127/) - [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/) - [Established PDF/UA‑1 conformance across nine documents at 106 of 106 rules, and found the archival variant failing one rule of 146 — a near‑miss that reads as a pass to anyone not running the validator.](https://engineer.company/portfolio/established-pdf-ua-1-conformance-across-nine-documents-146/) - [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/) - [Built a cross‑language content check that fails when a translation drops a figure the English states, and when a language uses notation it does not use — finding two Danish descriptions missing a metric and sixteen Ukrainian spans quoting in the English style.](https://engineer.company/portfolio/built-a-cross-language-figure-and-notation-check-153/) - [Wrote a parser that reads the real 7,308‑line C header and verifies every call site, every enum constant and that every pointer‑owning class is final, after a hand‑written placeholder header let calls to three removed functions compile, link and crash.](https://engineer.company/portfolio/wrote-a-parser-that-verifies-every-ffi-call-site-157/) - [Rewrote the application's error messages against a written tone standard after a refused sign‑in blamed the user for mistyping when the provider actually required an app‑specific password, and covered it with a test that names the provider.](https://engineer.company/portfolio/rewrote-the-error-messages-against-a-tone-standard-162/) - [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/)
