What I'm looking for

I'm looking to own backend services end to end, from API and LLM-pipeline design through deployment, monitoring, and reliability. I value practical work on production systems, automation, and infrastructure.

I've built production LLM pipelines for a Japanese tech startup that turn URLs or briefs into video ads and landing pages.

I designed reliability controls for non-deterministic model output, including circuit breakers, concurrency limits, endpoint model selection, layered validation, and bounded repair loops. I also added event logging and run snapshots so long-running generations can recover after failures.

I've deployed and migrated backend services with Docker Compose, NGINX, Prometheus, and Grafana, and built LINE Messaging API bots with webhook verification, conversation state, CRM automation, and follow-up triggers. At Avintis, I deployed AgentHub and migrated Billbot from a hardcoded Node.js backend into modular n8n workflows.

I also run CraftRift, a self-hosted Minecraft server hosting business, where I operate Linux infrastructure, customer-isolated containers, Cloudflare Tunnel, Zero Trust SSH, monitoring, and customer support.
