Professional Summary

2nd-year BTech student in Communications and Computer Networks at Technical University of Kenya, building at the intersection of cloud security and intelligent systems. Currently developing CloudGuard — an agentic AI tool that uses LangChain and Boto3 to audit AWS environments for security misconfigurations — alongside AutoVerifAI, an ML-powered fraud detection system for Kenya's asset financing market, and an enterprise data warehouse. Actively seeking internship opportunities in cloud security, AI systems, or network engineering. Member of the IEEE Student Society.

Project Experience

CloudGuard — AWS Security Auditor

Personal Project
2025 — Present
  • Building an agentic AI tool using LangChain and AWS Boto3 that autonomously scans AWS accounts for security misconfigurations including open S3 buckets, overprivileged IAM roles, and unencrypted databases
  • Designed Terraform scripts to deploy a secured AWS baseline environment with restricted IAM roles, encrypted RDS instances, and private VPC subnets
  • Generating automated, human-readable remediation reports so non-technical stakeholders can understand and act on security findings
  • Containerised with Docker for portable deployment across development and production environments

AutoVerifAI

Personal Project
2025 — Present
  • Designed an ML-powered risk scoring engine using Scikit-learn and XGBoost to detect fraudulent asset financing transactions in Kenya's car and heavy machinery market
  • Built a document forgery detection pipeline to verify asset ownership and valuation claims before funds are disbursed
  • Architected a FastAPI backend with PostgreSQL for audit trails, explainable AI outputs, and real-time risk verdicts
  • Containerised the full stack using Docker for portable, environment-agnostic deployment

Enterprise Data Warehouse

Personal Project
2025 — Present
  • Designed dimensional data models using dbt on DuckDB — a fully free, local-first analytical engine
  • Built scheduled ETL pipelines with Apache Airflow to consolidate siloed data sources into a single source of truth
  • Created interactive analytics dashboards in Apache Superset surfacing real-time business KPIs
  • Stored raw and processed data layers on AWS S3 as a cost-effective data lake foundation

Education
