Website with Community Portal (Web App)

Africa Speaks


Africa Speaks is a network of publishing professionals from around the globe united in a common goal: to establish a viable and flourishing Christian publishing industry in Africa 

I designed their website and community portal on Adobe XD and later developed it into a WordPress theme.  The community portal is a web application that runs on the CI4 Framework however some content is fetched via the WordPress API!

WWordPress Theme Customisation

MCCK Advocates


MCCK Advocates LLP is a Kenya-focused boutique law firm offering local solutions with international expertise.

I customised a premium WordPress theme to the brand’s colours and typography and the result was a very sleek, corporate and contemporary legal website!

WWordpress Website



RCA is an insurance agency based in Nairobi, Kenya.

I designed this website on Adobe XD and built the concept into a WordPress website. The site has a insurance premium calculator which is connected to a CodeIgniter4 backend that relays data to an Insurance SAAS known as Insurance Cloud

Mobile & Web App Solution

Nawiri Insurance


Designed & built a website and mobile application for Nawiri Insurance Agency. 

Nawiri’s website will enable its users to compare quotes from various insurance companies which the user can purchase.  The mobile app provides the same functionality creating convenience for existing and new customers. 

Web App Solution


2022 – 2014

The PRSK Awards Portal is a web application that provides a judging platform where participants upload Public Relations Campaigns as entries.

Judges then award their scores to the entries and at the end of the process the admin generates a score report for the entries.

Before the system, this was a very tedious and expensive process because:

  1. Materials (Paperwork and CDs) were sent by physically to PRSK
  2. PRSK had to hire venues for judges to collaborate on scores
  3. Scoring was done on selective spreadsheet software and error prone depending on the process of transmission

After using the system:

  1. Judges were flexible to judge at the comfort of any location
  2. As scores streamed in, it was possible to see preliminary score reports as opposed to doing a final tally
  3. Elimination of errors by transmission

I have actively developed, deployed, improved and supported the PRSK Awards Portal for over 8 years. 

The portal is built using CodeIgniter4 framework.
