Ndemafia Wilsmith

Cybersecurity Researcher & Full-Stack Developer

Securing high-stakes digital assets while building robust, scalable web applications. I find the flaws that put millions of people’s records at risk, then engineer the systems that do not have them.

ESI Abu Dhabi delegate, fully sponsored

What I do

Two disciplines, one mindset

I break systems for a living. That is what makes the ones I build hold.

Security research

Access-control and authorisation testing

Responsible disclosure

Reports engineering teams can act on

Full-stack development

Production web platforms, end to end

Secure architecture

Authorisation designed in, not bolted on

Shipped work

Platforms built to survive contact with the real internet

FLAGSHIPCORPORATE PLATFORM

B-Lord Group

blordgroup.ng

I designed and built the official B-Lord Group website from the ground up: brand system, responsive front end, content architecture, deployment and hardening. It is a public-facing platform for a group whose name carries weight, so it had to load fast, read clean and give an attacker nothing.

SECURITY TOOLING

Disclosure workflow tooling

Scripts and report templates that turn raw findings into the structured, reproducible reports security teams and national CERTs can act on immediately.

WEB APPLICATIONS

Client platforms & dashboards

Authenticated web applications with role-based access control, audited data flows, and an authorisation model designed before the first endpoint is written.

Case studies

Systems where the hard part was everything around the happy path

Data pipelines and applied-AI infrastructure, written up with the failure modes included: the bugs, the rejected designs, and the measurements that changed my mind.

International recognition

Representing my secondary school on a global stage in Abu Dhabi

My secondary school selected me and covered the full cost of attending MILSET Expo-Sciences International (ESI) in Abu Dhabi, one of the world’s largest gatherings of young scientists and technologists, where I showed my technical work alongside delegations from across the globe.
