This is exactly what I'm doing right now. Small businesses are being thrown HTML files and told to figure it out, it's crazy.
So I do the opposite and take care of everything. Design, build, deploy, maintain and update. I'm not a designer, but I take cues from their logos, menu, etc. I run it in the nearest AWS region for low latency, optimize all the assets, http2, etc. I strive to follow every best practice, within reason.
For a craft beer pub[0], I pull their current beers on tap from the Untappd![1] API, so the beers are always up to date. I also made a beautiful responsive menu that works great on mobile, tablet and desktop.
Where I'm really lacking is in self promotion. I do great work, but putting myself out there and selling myself is difficult. I will get there, though!
I'm doing this all to land a job doing front-end web dev somewhere I can grow my skills more. I came to programming late, but it is my passion.
Any thoughts on my site[2] would be much appreciated.
