Data Engineer building scalable ETL/ELT pipelines and data services.
ZimbabweWhat I'm looking for
I’m a Data Engineer with 2.8 years of experience building scalable ETL/ELT pipelines and data platforms. I focus on turning messy inputs into dependable, production-ready data flows for analytics, reporting, and onboarding.
At MADTECH.AI (Jul 2023 – Feb 2026), I built automated ingestion pipelines using Airflow and PySpark—detecting daily files, preprocessing data, updating ingestion status, triggering Airbyte loads, and refreshing Redshift materialized views. I also automated client onboarding end-to-end with Airflow, Airbyte, S3, AWS Lambda, and Redshift, reducing setup time by 80% (8h → 1h).
I build the services around the data: I developed secure outbound REST APIs using Flask on AWS Lambda with RDS/API Gateway, including JWT authentication (access/refresh), validation, rate limiting, and pagination. I used dbt to manage and version-control client-specific materialized views, safely updating transformations during new client onboarding.
I’ve delivered measurable scale and reliability too—resolving 30K+ duplicate records across multi-client schemas, optimizing Redshift materialized views integrating GA4/Facebook Ads/external sources to improve cross-platform consistency by 95%, and reducing manual dashboard operations by 70% through AWS Lambda + API Gateway microservices for Superset cloning, alerts, and metadata replication.
