I engineer data systems that work under pressure – production ETL pipelines, governance‑aware analytics, and AI applications built for industries where accuracy isn‘t optional.
Python · dbt · Airflow · LangChain · RAG · FastAPI – available for remote and hybrid engagements globally.
Rare combination: Data engineering depth + criminology/investigative thinking. I build systems that are accurate, auditable, and built to withstand scrutiny – ideal for fintech, govtech, compliance, and regulated industries.

What You Get Beyond the Tech Stack
Three edges that make me a better hire for data‑intensive roles.
Governance‑First Engineering
Criminology background means I build data systems that understand compliance, audit trails, and regulatory risk from day one. No “retrofit governance” later.
Africa‑Context Systems
4 years building for Kenya and East Africa means I understand infrastructure constraints, local regulatory frameworks, and real‑world business needs.
Ship, Don't Just Code
8 production systems deployed, not 8 GitHub repos. I build systems that go live, stay live, and deliver measurable business impact.
Flagship Systems
End-to-end intelligent systems demonstrating architecture decisions, pipeline design, and real-world impact.
Bank Compliance Analytics Dashboard
Problem: A Kenyan financial institution's compliance team spends 40+ hours monthly manually producing regulatory reports across fragmented data sources, with no automated alerting when KPIs approached breach thresholds.
Solution: Power BI dashboards with dbt transformations. Real-time compliance monitoring for Kenyan banking regulations. Automated alerting for regulatory breaches.
IMPACT
95% reduction in manual compliance reporting
JobScout KE — Automated Job Hunting System
Problem: Job seekers manually checking 7+ platforms daily missed time-sensitive postings — the fragmented job market meant relevant roles expired before candidates found them.
Solution: Automated job aggregation system using Streamlit, Gmail API, Jooble API, Groq LLaMA, and Playwright. Multi-source scraping with Telegram notifications.
IMPACT
Automated job search across 7 platforms. Real-time notifications.
Kijani Care 360 — Environmental Monitoring Platform
Problem: Environmental NGOs and field teams tracking tree planting initiatives across Kenya had no centralized, real-time system to monitor survival rates, regional suitability, or impact metrics — leading to delayed reporting and duplicate field work.
Solution: Geospatial ETL pipeline + PostgreSQL/PostGIS. Real-time dashboards tracking 10,000+ tree planting records across Kenya. FastAPI backend, React frontend.
IMPACT
Monitoring 10K+ environmental records in real-time
Kipaji Chetu — AI Adaptive Learning Platform
Problem: Teachers in under-resourced schools have no scalable tool to deliver personalized assessments - every student received the same quiz regardless of performance level, and feedback was slow and manual.
Solution: AI-powered personalized learning system with adaptive quizzes, real-time feedback, and teacher analytics. Built with FastAPI, PostgreSQL, and LLM integration.
IMPACT
Automated personalized learning and feedback system with adaptive difficulty and real-time analytics for students and teachers.
Safari Scout — AI Travel Assistant
Problem: Travelers planning Kenya safaris spend 10+ hours manually researching across dozens of fragmented sources, booking sites, travel blogs, forums, with no single reliable, conversational interface.
Solution: LangChain + Weaviate vector database RAG pipeline. Semantic search across 2,000+ curated Kenya travel experiences. Deployed FastAPI backend + Next.js frontend.
IMPACT
Reduced travel research time by 70%. Processed 2,000+ curated experiences with 94% retrieval accuracy.
Experience Snapshot
4+ years building production data systems across fintech, civic tech, and environmental sectors.
