For the past ~5 years I have built SaaS apps from the ground up and brought them to anywhere between 100 and 1,000 users. Some projects have been more technical (full stack w/ cloud deployment) while others have been purely business-oriented (courses hosted on Gumroad). My latest project is an AI Text Detector called Albott, which you can learn more about by clicking the image.
I have done front-end (React/Typescript), backend (Postgres), and data (Python, SQL, R) projects. My “home” language is Python, which I’ve used to make tools that can take in hundreds of thousands of inputs at scale and that I use in my own life daily. Almost every single project I’ve every built is on my Github, which you can go to by clicking the image.


My first full time job was a technical sales position managing a quota of ~$3 million quarterly, with an ACV of anywhere between $50k to $250k. But even outside of that I’ve built sales and marketing campaigns for my own projects, including $500 Pinterest campaigns that have led to thousands of MAUs as well as copywriting for private clients (as seen in the example image).
Creative work (writing, game design, music) is my home, and while it’s mostly been a hobby of mine I bite at the chance to help work on anything in the creative space. I have experience shipping in the Unreal and Unity engines, and have been writing fiction for 10+ years. You can look at my fiction writing portfolio here, or click the image to see my game development work.


I went to school for Finance and Economics, where I helped manage ~$1 million of the university’s endowment fund. Afterwards I built a quantitative trading algorithm that made ~45% return YoY, while staying resilient during sharp market downturns. This algorithm, just like most of my work, is open-source and freely available. Click the image to view the code.
I own a holdings company titled JBR (those are my initials, Jacob B. Robinson). I am also a private investor in Substack, Gumroad, Mercury, and Rasa Coffee. I wrote the books Boys & Girls and Baby Bird. Finally, I have a (somewhat) weekly newsletter that lets you know about the five most important things I read that week. You can subscribe to by pressing the button right over there.
If you like what you’ve seen so far, something tells me we’d work great together. I’m always looking for consulting, freelance, and full-time opportunities. Send me an email at jacob@jbr-holdings.com to let me know what you’re looking for.
