Selected work

Design, data and security projects, each with the problem, the process and what came out of it.

Latest case study, Nov 2026

Cybersecurity Threat Intelligence Dashboard

A High-severity attack was as likely to be ignored as a Low-severity one.

40,000 security events, cleaned and tested in Python, then turned into a seven-page Power BI dashboard. The finding that matters: response did not follow risk.

About

Jesse Nasamu standing against a warm wall

Most products are designed by one team, measured by another and secured by a third. I've trained across all three, so I tend to ask the questions that fall between them.

  • Will people understand it?Research, clear hierarchy and accessible interfaces.
  • What does the data say?Clean data, honest measures and dashboards that answer real questions.
  • How could it break?Security awareness from network cabling up to the login screen.

I studied cybersecurity at Bingham University, graduating with a 2:1 in 2024 and writing my thesis on threats and vulnerabilities in healthcare IoT. Alongside the degree I was designing interfaces, and a 2023 internship at the National Centre for Artificial Intelligence and Robotics (NCAIR) gave me hands-on practice in user research, prototyping and interaction design.

Since then my work has moved between the screen and the server room. I installed network and surveillance infrastructure at Jetra Limited, and at Galaxy Backbone I supported clients while analysing incident and service request tickets every week and month to find recurring issues and bottlenecks. Today I'm Chief Product Officer at Zap24, where I set product direction, research customers and decide what gets built next.

The common thread is how I approach a problem. I start with the people who'll use the thing, check what the data actually says, and think about how it could fail or be misused before it ships.
