# Jacob Robinson > Full-Stack Engineer, AI/ML SME Location: San Francisco, California, United States Profile: https://flows.cv/jacobrobinson I've worked in investment banking, sales engineering, and product management. I ran my own company solo for three years. I'm a private investor in Gumroad, Substack, Mercury, and Rasa Coffee. I've written four fiction books and scaled to 10k+ monthly readers across my web series. I've also done some side projects in content creation, game development, and algorithmic trading. Oh! The AI thing. Did I mention the AI thing? I've built AI agent systems in multi-million dollar businesses using OpenAI, Claude, and Gemini -- using first-class cost optimization, security hardening, and one-shot rates of over 75%. Okay, now I think that's everything. Here are some good reasons to reach out to me: - You are a curious person and just want to reach out to see what happens. These are my favorite! Let's chat, feel out the vibe, see where things take us. - You are an *in-house* recruiter who is hiring *for your own company*. I will generally respond to these, even if I'm not in the market for a new position right now. Usually there's someone in my network looking for a job and I can just refer you to them instead. - You are working on a project and want to pick my brain for advice. Yes, yes yes yes. I am always ready to give pro-bono, mostly unsolicited advice -- especially if it's something particularly weird and fascinating. Here are some bad reasons to reach out to me: - You are a third party recruiter trying to hire for a "stealth startup". These are usually poor-quality opps at best, and scams at worst. I may give you some leeway if you're able to at least give me the name of the company you're recruiting for. - You are asking for a referral. As a general rule, I don't do referrals for anything. Sorry! - You are a sales person trying to sell me things. Particularly, "Linkedin lead generation". Why would you even think I need this? I didn't even need this when I ran my company full-time. And even if I did need it, I could handle it on my own. ## Work Experience ### Full Stack Engineer @ Lumafield Jan 2025 – Present | San Francisco, California, United States I create customer-facing apps using Cursor agents on a React/Typescript/Python/Django stack. ### Founder @ JBR Holdings Jan 2020 – Present | San Francisco Bay Area Built full-stack 0 -> 1 production apps using Cursor.
