What I'm looking for

I’m looking for a role where I can build meaningful, user-focused products with a team that values clarity, trust, and async collaboration. I work best with autonomy, ownership, and a shared mission to create something genuinely useful.

I’m a Full‑Stack Software Engineer at Firecrawl, focused on integrations and developer experience for our open‑source, AI‑driven web data platform. I build resilient, scalable systems that connect Firecrawl to tools like Zapier, Make, n8n, LangChain, LlamaIndex, Dify, and more, while improving dashboards for orchestration, monitoring, and high‑volume data extraction.

Previously, I led engineering at refurbed and shipped enterprise frontends at Mercedes‑Benz.io and MotorK, serving thousands of users across multiple markets. My work centers on reliability, speed, and ease of use—backed by experience in Vue/TS, gRPC, and modern web architectures.

I’m passionate about open‑source, technical writing, and creating automation that turns messy web data into clean, LLM‑ready outputs. Verified leadership, mentorship, and system thinking; MBA in Software Architecture.
