Er I’m sorry but 1 counts as a portfolio bro…esp if done very well…
Just show your clients your work and be confident… guess you don’t feel confident about the sites you mentioned.
Rarely do clients actually ask to see past works if you are confident, gotten away without showing past works even though I have got…just talk your way out of it 
Some of us are waiting for @xolubi to notice this thread and fufil the above prophecy. How hard can it be to stay out of one thread? We all know it’s not that easy
I love my Radar. 
Still haven’t gotten over that one, yea? Pity. I’d really like to meet you in real life, arrange a sit-down, hear about the roads you have walked that made you like this, examine your shoes. You can hit me up on Skype.
@Engrtitus its like the Nike slogan, “Just Do It”. You might have to kiss a few frogs i.e.(pro bono a.k.a free work) but one day one of those frogs will turn to Prince Charming. You don’t even need to host anything, just design and keep and when you walk into your next interview, show with a flourish. Best of luck out there. Peace.
If the two of you are in Lagos, this could happen sooner than you think 
First Do you have a github account?
A showcase to prospective consumers who don’t give a damn about design process or to brag to fellow developers? How does this relate?
That’s quite a few possibly erroneous assumptions. Actually, Github is a lot more than this. And for the OP’s purposes, it does relate. As even more DIY technologies proliferate, consumers are beginning to give a damn or two, or even three about the process. For anyone whose work is even remotely related to development, a Github account is just as, if not more valuable than a LinkedIn profile.
He kind of already said he didn’t have (and was looking for how to build) a portfolio though. I didn’t see how the question was relevant either.
Let’s agree it’s valuable and GitHub is to be considered. It’s definitely not the first thing to consider as mentioned by @biodun.
However, using GitHub profiles in particular, as a hiring filter is bad for our industry.
One creates a GitHub Account and feels GitHub is his/her new resume?
It’s a beguiling story to tell ourselves, after all, hiring is hard, trust me, I’ve been there, and what could be a more objective way to screen candidates than to just look at their code?
You’ll however agree that;
GitHub profiles simply don’t tell you what you think they tell you. Right?
There is really astonishingly little value in looking at someone’s GitHub projects out of context. For a start, GitHub has no way of customising your profile page, and what is shown by default is the projects with the most stars, and projects recently pushed to. GitHub picks the most popular repos and puts those at the top. You have no say about what you consider important, or worthwhile, or as you mentioned, ‘valuable’. You just get what other people think is useful. Aside from which, GitHub displays a lot of useless stats about how many followers you have, and some completely psychologically manipulative stats about how often you commit and how many days it is since you had a day off. Like seriously?
If showcasing how 'influential’ one is, and how easily one can be coerced into constantly working. It’s honestly about as relevant to a decent hiring decision as a Klout score.
I have more context if need be. But you get the point. This dude is just starting out and GitHub should just be for backup, collaboration, pull request or issue tracker.
All this plenty thing because a brother just want to l’owo, l’ola and l’alafia. And be alright. Sigh.
