# Ed Chapman

> Software Engineer | Building Systems End-to-End | Python, Django, AWS, Terraform, React

Location: London Area, United Kingdom, United Kingdom
Profile: https://flows.cv/edchapman

Software engineer with 9+ years building data-intensive, cloud-hosted systems across PropTech, energy, and food supply chains.

I specialise in backend architecture (Python/Django), cloud infrastructure (AWS/Terraform), and CI/CD automation with enough frontend (React) to ship end-to-end.

At Built AI, I developed product features, built internal tools, managed the cloud infrastructure and CI/CD pipelines for a SaaS platform used by institutional real estate investors to model cashflows and manage portfolios:

- Reduced page load times by ~50% through systematic database query optimisation
- Designed and built a greenfield data ingestion pipeline from spec to production
- Led MySQL → PostgreSQL migration using Terraform and AWS DMS
- Authored Terraform across 12 modules and 5 environments
- Built GitHub Actions workflows replacing CircleCI
- Coordinated production releases across engineering and product

Previously: Tech Lead at Natoora (supply-chain platform), Software Engineer at Kraken Technologies (Octopus Energy Group).

I care about building systems that work reliably at scale, making infrastructure observable, and leaving codebases better than I found them.

Open to Backend, Platform, and Full-Stack Senior Engineer roles.  My priority is people and mission, I enjoy feeling part of a team and that my work is meaningful.
