I build backend & AI systems from scratch — the kind most people reach for a framework to avoid.

At Lunacal, I own features end-to-end for a scheduling platform used by 10k+ people: a recurring-events booking engine, a client portal with per-guest cryptographic access, an MCP server, and HubSpot / GTM integrations.

On my own time I built a RAG-based AI code reviewer with no RAG framework — Tree-sitter AST chunking, OpenAI embeddings, pgvector retrieval, idempotent exactly-once processing. All by hand, on purpose.

I care about the layer beneath the one I work in — and I write about it. 👇
