Full-stack developer focused on AI products, agentic systems, and automation.
My recent work has been around building practical LLM-powered systems rather than simple chat interfaces: multi-step agent workflows, tool/function calling, structured outputs, persistence, approval pause/resume flows, retries/checkpoints, streaming, API integrations, and automation pipelines.
Projects include PersonaChat, AI-powered web products, Discord bots, ComfyUI/ComfyDeploy workflows, and agent systems combining backend logic, databases, external APIs, and production deployment.
I’m looking for a remote Software Engineer / AI Engineer / Applied AI role where I can work hands-on on agents, automation, LLM integrations, backend systems, or AI-native products.

I build and run PersonaChat (personachat.chat), an AI character chat platform on Next.js and Supabase — live since 2025, built and operated solo.
Production LLM work rather than demos: streaming chat over the Vercel AI SDK; a long-term memory layer with append-only writes and invalidate/supersede semantics, idempotency keyed on source turn ID so a dropped stream never duplicates a turn; a relationship engine holding state across sessions that feeds back into generation; and the same character system running through a Discord surface, which forced the state logic out of the components into a shared layer.
I also instrument and read my own funnel in Postgres rather than guessing, and I run Claude Code daily against structured specifications rather than prompts — agents write most of the code, the spec and the review are the job.
Open to full-time or contract. Full overlap with European hours, mornings with US Eastern.
