Data and AI Engineer

Cleavestone Adungo

I build the data pipelines and ML systems that businesses run on.

SQL-first data engineering with dbt and BigQuery, plus production machine learning: demand forecasting, computer vision, route optimization and LLM applications. I am a Data Engineer at Solutech, building for FMCG manufacturers and distributors from Nairobi.

Background

Data and AI Engineer who builds production data pipelines and the machine learning systems that run on top of them.

Currently at Solutech Limited, I own end-to-end analytics engineering — ELT pipelines that power manufacturer-facing dashboards, dbt transformations in BigQuery built on a medallion architecture (bronze → silver → gold), and monitoring of production Prefect pipelines — while leading an end-to-end computer vision project for retail shelf analytics, owning everything from annotation strategy through model training to production deployment. As part of this, I also build customer-facing dashboards in Apache Superset and Looker Studio.

On top of the warehouse I deliver demand forecasting, route optimization and computer vision systems, served as APIs so teams can use them in daily operations.

Outside my day-to-day role, my recent focus has shifted toward agentic AI system design: ReAct-style tool-calling agents, task planning, hybrid memory, and self-reflection loops, packaged as streaming production APIs. I design these systems with cost optimization, auditability, and data-privacy compliance (GDPR-aware handling) built in from the start — the same production discipline I apply to data infrastructure.

What I Do

Data Pipelines and Analytics

ELT pipelines, dbt models and BigQuery warehouses that turn raw operational data into trusted, analyst-ready datasets and dashboards in Superset or Looker Studio.

Good fit if your data sits in scattered systems and reports are slow or inconsistent.

Machine Learning in Production

Demand forecasting, route optimization and computer vision, deployed as APIs and wired into daily operations.

Good fit if you want predictions or optimization built into how your team works.

AI Automation

LLM applications, retrieval-augmented generation (RAG) and text-to-SQL agents with cost controls and guardrails.

Good fit if your team wants to query data or documents in plain English.
