Saad Irfan

Software Engineer @ Tesla

I build platforms that are scalable, high-performant, and developer-friendly, with a strong focus on system design and applied AI.

Currently, I'm working as a Software Engineer at Tesla. Previously, I was at Langbase, where I worked across a wide range of products, including Command.new, an AI agent platform that scaled to 10K+ users and 100K+ agents within two months. I've built core systems like agent lifecycle management, code versioning, LLM thread infra, multi-tenant orgs with RBAC, and API key management at scale, helping support 500M+ monthly agent runs.

I work end-to-end: shipping products in React/Next.js, designing APIs/SDKs in TypeScript/Python, and keeping backends fast with strong observability (queues, caches, tracing, SLOs) for workloads like model routing, function/tool calling, and evaluation loops. I target sub-200ms p99s, sane metrics, and small, reusable primitives that teams actually adopt.

Beyond shipping, I put time back into the developer community; writing docs and examples, sharing learnings through posts/AMAs and livestreams, mentoring, and contributing to open source. I believe great DX is community work. I work at the intersection of developer experience, product/platform engineering, and applied AI (LLMs, retrieval, agentic workflows); shipping full-stack features for AI products and developer platforms.
