What I'm looking for

I'm looking to build production-ready backend and database systems where I can combine AI-augmented delivery with rigorous testing, security, transactional integrity, and continuous deployment.

At Magne Studios, I build and validate backend data systems for medical imaging, real estate, B2B marketplace, legal mediation, and manufacturing products. I translate functional requirements into PostgreSQL schemas, versioned migrations, transactional logic, and automated delivery pipelines.

I pair AI-augmented development with rigorous technical control: pgTAP, Vitest, Python integration tests, manual UI/UX QA, log triage, and CLI verification. My focus is ACID consistency, Row-Level Security, multi-tenant isolation, and reliable Supabase deployments.
