Looking for a personal "landing page" (design + coding)

I am looking for the design and coding of a personal landing page: something I can point people to and that contains links to other materials (Linkedin, TripAdvisor, Facebook, Home Page, Alumni pages...), with some brief intro and a coherent design.

What I am looking for:
- Simple, focus on good SEO.
- Adaptive, should be ok from different devices
- Clean: should include different content (personal sites, professional sites in a good way). Most interest would probably be professional.
- HTML + CSS, if you want PHP or others but nothing that requires a complex tech setup.
- Allow for some space for widgets (e.g.: twitter feed, where I am next, Calendly have a chat...)
- Complete and operational: I am looking for a single set of sources I can dump into a server and that I can modify if I have new links or material (I'll provide a first set of links/widgets). Not something that requires extra coding or extra work.

I can share examples of the current solution in place if interested.
