About

Integration engineer.
Full-stack depth.

I specialise in enterprise API integration - designing event-driven architectures that connect SaaS platforms, cloud databases, and custom backend services without friction.

My work spans two disciplines: MuleSoft / Anypoint Platform for enterprise integration, and Python (FastAPI, Django) for backend services and automation pipelines. Both serve the same goal - systems that don't break.

Before Systems Limited, I worked across EdTech, fintech, and large-scale scraping projects - building a strong foundation in performance, data integrity, and async processing.
