The most amazing...
...thing I've done was transforming the bottle-necked physical IT infrastructure of a fintech to a hybrid cloud that was modern, secure, and easy to administer.
Employment
Experience
- HeptaPayhttps://heptapay.com
An online agent for loading money to a mobile money wallet via debit or credit card. As the integrations engineer, I set up the card processing payment gateway and connections to the telecommunications partners; tested these connections for security and performance; and managed the back end, the internal transaction monitoring dashboard, and the platform's security.
- Sentiment Analysis of the 2017 Kenyan Presidential Electionhttps://uchaguzi.today/
Kenya held a general election in 2017. We built Uchaguzi Today to show the trends behind each candidate's popularity and explain (via regular updates) the actions they performed that elicited a positive, neutral, or negative response. My involvement was setting up the infrastructure for collecting the data, interacting with the Twitter API to collect the tweets, designing and deploying the dashboard, and deploying an Android application to classify a sample dataset to help train the model.
- Email Server Audit
This project was brought about by suspected malpractice on the ICT systems of a tour company—particularly the email system. The company owners were the project champions. The purpose of the project was to identify any possibilities of such malpractice on the ICT part, recommend solutions, and implement the solutions where possible.
This project was carried out in three phases remotely and through three regional trips to the Arusha headquarters:
Phase one involved a forensic analysis of the mail system to identify instances of foul play. Malpractice was indeed identified, and the evidence was presented to the project champions.
Phase two was implementing a solution that migrated the mail server to a secure cloud virtual private server running with encryption and email antivirus and anti-spam mechanisms in place. This migration was done seamlessly and successfully with minimal business impact.
The final phase was the optimization of office ICT systems for both performance and security. This phase further involved configuration of the mail server to suit organizational needs, such as particular accounts to be limited to internal-only communication.
Overall, the project was a great success.
