Open to full-time and contract roles
Building dependable cloud platforms and data systems.
I’m Elijah Campbell, a Data and Cloud Engineer designing scalable pipelines, distributed processing systems, cloud-native infrastructure, and analytics-ready platforms.
01 / About
Engineering systems that remain useful after deployment.
My work connects cloud infrastructure, data engineering, backend APIs, and operational reliability. I design for performance, data quality, observability, cost efficiency, and maintainability—not just successful demos.
02 / Selected Work
Technical projects presented as engineering case studies.
Project RISING
A climate-driven disease burden platform for ASEAN health resilience, combining validated public-health datasets, ETL foundations, analytical processing, and a FastAPI intelligence service.
Fragmented health and climate datasets made reliable analysis and early-warning workflows difficult.
Created a modular ingestion, validation, transformation, intelligence, and API architecture with operational safeguards.
Added schema validation, deduplication, retry and DLQ concepts, CI workflows, clearer errors, and architecture documentation.
Live GitHub repositories
Automatically loaded from GitHub and sorted by recent activity.
03 / Architecture
A modern data platform, from ingestion to trusted delivery.
Design for failure
Retries, validation, idempotency, monitoring, and recovery are part of the architecture.
Automate the platform
Infrastructure as code and CI/CD make environments repeatable, reviewable, and safer.
Measure the outcome
Performance, cost, reliability, and data quality are engineering outputs—not afterthoughts.
04 / Experience
Hands-on delivery across data and cloud systems.
Data Engineer Intern
Led scalable cloud data-pipeline development, supported storage and infrastructure optimization, improved production query performance, and contributed to distributed processing and real-time analytics initiatives.
- Reduced pipeline processing latency by 30%.
- Improved database and query performance by 40%.
- Helped reduce infrastructure costs by £10,000 per quarter.
