What I'm looking for

I’m looking to build and ship production ML platform and data pipeline systems—reliable ETL, cloud infrastructure, and automation—while working with strong code review, testing, and a collaborative culture that values integrity and scalability.

I’m a backend and ML platform engineer with production experience building data pipelines, database schemas, and cloud infrastructure for large-scale systems. At ShoutOut Labs, I ship Python/TypeScript services on AWS and Supabase, including multi-stream ETL with integrity validation, queue-driven processing with Bull/Redis, and CI/CD automation with code-reviewed, tested releases.

I apply computer vision (OpenCV, CNN defect detection) and have published ML research on a low-resource NLP & ML platform, achieving strong results versus baseline and deploying it via REST APIs. I also bring a strong engineering foundation as a First Class Honours BSc graduate (GPA 3.84/4.00) and enjoy mentoring through IoT lecturing and supervising hardware–software integration projects.
