I will be explaining every single program starting from the beginning.

Money was invented to control people's economy. They know everyone can not have access to cash.

Some will die poor, many can not afford hospital bills or even feed.

Permit me friends, to say that money �� has no value.

Giant companies are after people's data, now stop envying billionaires or saying bad stuff about them.

Start growing your own data cus it is the oil of today's economy.

No one can have access or control your data. It is yours forever..

Stop pursuing money start building data or taxation/recession will take all your money away.

� I have a Talk Show on 20th of August in regard to how #AI #MachineLearning #DataScience have affected the world economy and how we run business.

Venue: WhatsApp
Time: 8pm West Africa Time

You can join as audience �

#DEVCommunity

Speaker: Aspiring Data Scientist.
Upcoming Statistician
Passionate Developers

We have been developing softwares, website and mobile application for quite a long time now.

I am much more concern about business aspect, let's turn your project into a multi billion company here and now.
�� [1/5]
#businessdevelopment

Few developers are business oriented folks, which is the most intrinsic part of softwares.

Taking your app public for Users will expose you more to what exactly users may like.
[2/5]�


The UI/UX design used will determine how interesting the user may find it.

Visual appealing design are more important to users, they tend to stay or never to come back.

Plan a good UI

�[3/5]

Now you want to measure your performance and how user interact with your software or website.

You need analytics software:
Google analytics is more preferable, the journey has just began.

Monitoring your progress on daily basis
�[4/5]

Funding! Not important now. First run the company independently by reducing cost:

Operate from home �

Never rent an office � until you have gotten your audience interest.

Work with friends � so you don't have to pay anyone until you start earning

Do you know:
The first Space Robot was coded in pure CSS.

This thread is a waste of server space.
Seun should just trash this!

Keep wasting your time learning various programming language.. HTML5/CSS3 are use to design all the apps or websites and softwares.

Wikipedia articles are outdated and are written by non experts. Keep reading their articles. More confusion....

Source code are equally available. Core HTML5/CSS3

More on ATM UI in transaction process

ATM UI created with HTML5/CSS3

Screenshot available, you can still watch the video @TimIyke1 Twitter account.

ABCthingx:
Op, how do I sum 1 + 1 and find the its square root using HTML 5

Can you show me your portfolios, let's start from there

ATM programs are still #HTML5 #CSS3 with #javascript

I created my own version Access Bank ATM with HTML5/CSS3.
