Improper Costing Techniques Could Be The Reason Your Software Development Projects Fail

Clients that need software built always want to know how much it will cost them, and a lot of times (at least as we have experienced at Intellectual Apps) they want to have this information before work begins. In order to get a “realistic” estimate of how much it will cost to build the piece of software, agencies would elicit the requirements and then based on that come up with an estimate of the cost. Client has a cost for getting their software built while the agency is happy they got the project. Great!

How to Use the Backend for Frontend (BFF) Pattern in Your Mobile Application Architecture

This article is a summary of my presentation at the O’Reilly Software Architecture Conference in London.

Maintaining an API gateway these days generally involves handling different types of user facing apps such as a web, mobile (of different platforms) and IOT devices. The Backend for Frontend (BFF) pattern specifically addresses this aspect of software solutions.

The Challenge

At Intellectual Apps we build software solutions, and in creating solutions for our clients we frequently get to build web and mobile apps within a single solution. This often means that we have a single API gateway for all the apps to communicate through. Over numerous clients/projects/products we started to notice a lot of repetition in the modules we built into software solutions, so naturally we sort to find a way we could share functionality across solutions in an easy way and this lead us to start experimenting with microservices.

How we built an election report-casting app!

We had always wanted to build something relevant for elections in Nigeria and we had a lot of talk around this subject in 2011 when the last general elections in Nigeria were held but never did anything more than just talk about it. So when the 2015 elections were around the corner again, the talk came back but this time we were determined to get something done, anything!It all started with an excel sheet containing around 118,000 records, polling unit records from all across Nigeria. Since each polling unit record had a geographic coordinate, we were able to plot all the records on a map. Here is a map of Nigeria showing all the polling unit data (Google maps):
