No dependencies or build step are required. All internal links work on GitHub Pages and a custom domain.
Serve the repository root with a local static web server of your choice, then open its local address in your browser. No build step, package installation or project-specific server script is needed.
The homepage introduces Gerko as a senior software engineer with a background in .NET, React, TypeScript and Azure. Amsterdam 750 remains the first project; Book RPG is explicitly described as experimental. Availability for new roles is stated in the introduction and contact section.
Both pages link to /#contact. The contact button opens the existing public
LinkedIn profile at https://nl.linkedin.com/in/gerko-schrieken-b1853246.
No private/account email, contact form, analytics or placeholder CV link is added.
Update the availability text when the job search changes.
In Settings → Pages:
- Select Deploy from a branch.
- Select main and /(root).
- Click Save.
The default address is https://gozzy82.github.io/.
First add gerko.amsterdam under Settings → Pages → Custom domain and save.
GitHub will create the CNAME file for branch publishing. Then replace existing
apex A records with these four GitHub Pages targets:
| Type | Name | Value |
|---|---|---|
| A | gerko.amsterdam | 185.199.108.153 |
| A | gerko.amsterdam | 185.199.109.153 |
| A | gerko.amsterdam | 185.199.110.153 |
| A | gerko.amsterdam | 185.199.111.153 |
For IPv6, replace old apex AAAA records with these GitHub Pages targets:
| Type | Name | Value |
|---|---|---|
| AAAA | gerko.amsterdam | 2606:50c0:8000::153 |
| AAAA | gerko.amsterdam | 2606:50c0:8001::153 |
| AAAA | gerko.amsterdam | 2606:50c0:8002::153 |
| AAAA | gerko.amsterdam | 2606:50c0:8003::153 |
Leave mail-related MX, SPF, DKIM and DMARC records intact.
Do not point wildcard records at GitHub Pages.
For www, add a dedicated CNAME from www.gerko.amsterdam to gozzy82.github.io..
Once GitHub provisions the certificate, enable Enforce HTTPS.
The previous ChatGPT Sites A targets and verification records are not used by this deployment. DNS propagation and certificate issuance can take time.

The Amsterdam 750 figures refer to the published five-minute load test with 250 virtual users, not a general scalability guarantee. Book RPG describes the documented implementation as reviewed in September 2026; it does not claim an aggregate reliability benchmark.
