What we build

Data engineering, full-stack development, and cloud infrastructure, delivered as one system rather than separate contracts.

01

Data engineering and analytics

Pipelines, warehouses, and dashboards that turn raw data into decisions — Kafka ingestion, PySpark transforms, BI layers on top.

Kafka PySpark Airflow dbt
02

Full-stack web applications

Django and React apps built for African operating conditions: mobile money, multilingual UI, offline tolerance, low-bandwidth performance.

Django React TypeScript PostgreSQL
03

Cloud infrastructure

Scalable deployments on AWS and OCI — infrastructure as code, containers, and cost-optimized setups for organizations with tight budgets.

AWS Docker Terraform Nginx
04

AI-powered features

Machine learning and LLM capability added to existing products — symptom checkers, opportunity matchers, predictive scoring, built on real data.

Built in Rwanda

Donambi Digital Solutions is operated by Thierry Donambi (Elthiero), a Big Data Analytics Master's student at AUCA and a full-stack engineer working across data engineering, cloud infrastructure, and product development.

Bilingual in French and English, serving both Anglophone and Francophone African markets without friction. The work spans agriculture, peacebuilding, retail, and social impact.

Every system here is built with African connectivity, mobile-first users, and local payment rails in mind — not adapted to them afterward.
