⚡ Architecting Intelligent Systems.

I am an AI Systems Engineer.

I build production AI infrastructure and research how to make intelligent systems work where resources are scarce — constrained hardware, limited connectivity, non-technical users. My work spans LLM orchestration, RAG pipelines, and agentic workflows, with a security-first approach grounded in ethical hacking practice.


🟢 Current Focus: Low-Resource AI

Pursuing an MPhil in Intelligent Computing Systems at Ashesi University, researching efficient AI in low-resource environments.

  • The Question: How do we build intelligent systems that remain useful when compute is limited, connectivity is unreliable, and users aren't technical?
  • The Stack: Lightweight model adaptation, retrieval systems optimized for constrained settings, semi-supervised learning for low-resource languages.

🛠️ Core Engineering Pillars

Intelligent Systems Security & Robustness Systems Architecture
Agentic Orchestration Adversarial Machine Learning Distributed Systems Thinking
RAG Pipeline Optimization Model Guardrailing & Safety High-Performance FastAPI Backends
Fine-tuning & Embeddings Secure SDLC Integration Cloud-Native Scalability

🏗️ Featured System: Meridian Policy Intelligence

A full-stack RAG application designed for high-precision corporate policy retrieval.

  • Key Metric: Achieved 96% Citation Accuracy and 93.5% Groundedness.
  • The Innovation: Implementation of a "Guardrail Prompt Template" and local CPU-based HuggingFace embeddings for cost-effective inference.
  • Design: Editorial/Brutalist UI built with Vanilla HTML/CSS.

🎓 Research & Development

MPhil candidate at Ashesi University (Intelligent Computing Systems) and MSc candidate at Quantic (Software Engineering). My approach is defined by:

  • Low-Resource AI: Researching lightweight model adaptation, semi-supervised ASR, and cross-lingual transfer for underrepresented languages.
  • Security-First AI: Protecting intelligent systems against data poisoning and prompt injection — responsible AI and accessible AI are the same problem.
  • Research-Driven Engineering: Applying academic rigor to production code, not just prototypes.

📊 Technical Arsenal

  • Languages: Python (Expert), TypeScript, Nodejs, SQL.
  • AI/ML: LangChain, PyTorch, HuggingFace, ChromaDB, Groq.
  • DevOps/Backend: FastAPI, Docker, Kubernetes, AWS/Heroku.
  • Security: Ethical Hacking, OWASP Top 10 for LLMs.
