Hi! My name is Nguuma, and I'm a Senior AI Engineer, Application Security Specialist, and open-source researcher. My expertise sits at the intersection of software, LLM engineering, and cybersecurity designing, building, and hardening secure systems across FinTech, healthcare, public sector, broadcasting, and security research. Over the past decade I have worked with organisations that cannot afford to get AI wrong regulated industries, vulnerable populations, and critical infrastructure and I have built systems they trust.

I hold an MSc in Computer Networks and Security from the University of Essex, and I am a CISSP-certified security professional one of the most respected credentials in the field. I have worked across some of the most impactful environments in AI and security. In FinTech, I have built an AI-powered analysis and fraud detection system, and designed and shipped a FinTech LLM application end-to-end that cuts broadcast episode production from 5–8 hours down to 3–4 minutes, with a full SAST audit returning zero high-severity findings across 2,777 lines of code. Before that, I was Technical Lead for PadiChat at RNW Media a private AI counselling platform I built from the first commit to production for young Nigerians seeking sexual and reproductive health support, holding 99.9% uptime and automating over 1,000+ routine counselling inquiries.

I have published three open-source fine-tuned small language models on Hugging Face, each built to run inside an organisation's own infrastructure with no sensitive data leaving the environment. My Security-SLM models covering the full AI attack surface from SOC triage to agentic lateral movement and RAG vector-store poisoning have surpassed 3,000+ combined downloads. I also publish Med-Lab-finetuned, applying the same methodology to clinical laboratory diagnostic reasoning for resource-constrained environments.

Aside from building, I am a sought-after voice on AI security and sovereign AI adoption. I have been cited as an expert in The Guardian Nigeria, Daily Trust, Radio Nigeria, Leadership Nigeria, and AllAfrica. I have spoken at GDG Build with AI 2026 and World Creativity and Innovation Day 2026, and I serve as an Independent Research Affiliate (AI/LLM Application Security R&D) at Entrick Information Systems conducting applied research into emerging LLM attack surface and secure AI adoption for regulated environments.

My career ambition is to be the engineer and researcher who proves that security and AI capability are not in tension that the most powerful systems are also the safest ones. I want to shape the standards by which the world's most sensitive AI deployments are built, and leave behind models, tools, and frameworks that make secure AI accessible to the organisations that need it most.
