Chukwunedum Davidson — Senior QA Engineer

Lagos, Nigeria · nedum.xyz · [email protected]

I own quality and release readiness for production software: browser, API, integration, and data-boundary testing across complex SaaS, backed by automation that gates real releases rather than decorating a report. Seven years in software engineering, the last several focused on senior quality engineering, release ownership, and product security research.

Responsible-disclosure work has earned public credit for 2 CVEs and 3 GitHub Security Advisories.

What I work on

• Release ownership — measurable acceptance criteria, explicit release gates, rollback conditions, and post-deployment verification.
• Test automation — Playwright, Cypress, pytest, and Python/TypeScript harnesses running deterministic integration, API, and failure-path checks in CI.
• Product security research — authorization, OAuth, multi-tenant boundaries, integrations, billing state, and cross-layer business rules.
• Shipped With Bugs — independent QA and responsible-disclosure research on B2B SaaS.

About this repository — source for nedum.xyz

A static Parcel build deployed on Vercel. Requires Node 22 or later (see .nvmrc).

npm install     # install dependencies
npm start       # dev server with hot reload, opens in browser
npm run build   # clean + production build into dist/

Layout

Path	Purpose
src/index.html	Page content and structure
src/css/	Sass sources
src/js/	Page behaviour
src/img/	Images and assets
dist/	Build output (generated, not committed)

Deployment. Vercel builds master and serves dist/. The custom domain is pinned by CNAME, and vercel.json permanently redirects the nedu-m.vercel.app fallback hostname to nedum.xyz so there is a single canonical origin.

Licence. The LICENSE file carries the MIT licence of the Codrops template this site was originally built from. Site content and copy are my own.
