Oliver B.
Backend Engineer | Workflows, APIs & Integrations | Elixir & Python
I build reliable backend systems: business workflows, APIs and third-party integrations that hold up in production. My specialty is Elixir, Phoenix and Ash, and I also work in Python. I’m comfortable joining an existing codebase and improving it without unnecessary rewrites. What I do well: Multi-step business workflows and ERPs REST APIs, webhooks and third-party integrations Background jobs, retries and idempotency PostgreSQL data modeling and data integrity AI and LLM integrations Clean code, predictable systems, and solutions sized to what your project actually needs.
