Professional Summary
AI systems engineer who designs and ships production AI — multi-agent platforms, RAG systems, and applied machine learning — for African and global markets, with a bias for systems that survive real-world constraints: low bandwidth, low-end devices, and multilingual users. Recent client work: the AI layer of Tapi Learn for ACLA, serving 11,000+ learners across 38 countries (EN·FR·SW, 4.8/5 client-reported), and Keja AI for CHACADOM INVESTMENTS — a 7-stage real-estate platform in public trial across 12 Kenyan counties. Creator of Busara AI (6-stage multi-agent DAG pipeline with statistics implemented from scratch), KilimoPRO (offline-first agri-AI for 8 IGAD countries, on-device TensorFlow Lite detection), and AgentReplay (deterministic replay for AI agents: 0.67% overhead, 100% reproduction fidelity, MIT-licensed). 5+ years shipping Go, TypeScript, Python, and Flutter systems, on a data-science foundation built inside Kenyan financial institutions (RBA, NSSF, Enwealth). Based in Nairobi — available for remote engagements worldwide.
Experience
AI Systems Engineer & Consultant
- Tapi Learn — client engagement for ACLA (2026): built the 24/7 AI Career Coach (CV reviews, interview prep, career advice), the multilingual NLP pipeline (English · Français · Kiswahili), personalized learning recommendations, and the opportunities board — serving 11,000+ learners across 38 countries with a 4.8/5 average rating (client-reported).

- FirstLight (Oct 2026): designed and shipped a self-initiated Geo-AI disaster-response demo — H3 need-score zoning, Dijkstra routing on post-event road graphs, hospital isochrones, human-in-the-loop review, and hash-verified situation reports.
- Deliver end-to-end engagements: needs assessment → architecture → build → evaluation → production deployment → team training. Clients span fintech, agriculture, logistics, real estate, and SMBs — from $2,500 assessments to $50,000+ multi-agent programs.
- Built the IntelliFlow platform — a 33-agent TypeScript system with self-evolving trajectory-based learning that became the foundation of Busara AI.
Creator & Maintainer
- Designed and shipped AgentReplay — an open-source deterministic replay and counterfactual debugging layer for AI agents. Records every LLM call, tool response, clock read, and RNG draw, then replays the run bit-exact with zero model calls.
- Measured 0.67% recording overhead (vs. 5% target; incumbents range 0–15%), 100% reproduction fidelity on the synthetic validation set, and 99 tests all passing.
- First-class LangGraph integration via
bind_graphcontext manager; adapters for OpenAI SDK, Anthropic SDK, CrewAI, AutoGen (v0.2 + v0.4+), and raw agent loops. - Counterfactual mutation engine — "would the agent still have done X if Y had been different?" becomes a 5-second, zero-cost experiment.
- CI regression runner: captured failures become permanent, zero-cost tests on every PR.
- Published a 22-minute research whitepaper covering the METR time-horizon research, the observability gap, and the full architecture.
- Stack: Python, LangGraph, OpenAI SDK, Anthropic SDK, Click CLI, mkdocs-material docs, GitHub Actions CI.
Creator & Lead AI Engineer
- Designed and shipped a multi-agent platform with a 6-stage parallel DAG pipeline (Ingest → Engineer → Detect → Forecast → Infer → Report) with circuit breakers and smart caching — serving live users at busaraai.com.
- Implemented real statistical algorithms from scratch: Holt-Winters forecasting, Z-score/IQR/EWMA anomaly ensembles, OLS regression, Granger causality, K-Means++ clustering.
- Integrated GLM-4.6, GPT, Claude, and Gemini into a multi-LLM council with streaming responses and citation-grounded RAG.
- Cut average analysis latency by ~40% via smart caching and parallel DAG execution.
- Stack: TypeScript, Next.js 15, React 19, PostgreSQL, Redis, Docker, Kubernetes, PWA.
Creator & Lead Engineer
- Built an offline-first Flutter app for African farmers with on-device crop disease detection via TensorFlow Lite — runs on $80 Android phones.
