Now building FileFreak.io
Sean Brill, Senior software engineerFrom first commit to live domain.
I design, build and run whole products, from the database to the pipeline that deploys them. By day I'm a senior software engineer at Prudential. The rest of the time I build FileFreak, the platform this site is served from, and the tools around it.

Things I've built.
Seven projects, from a developer platform to a restaurant's website. I designed and built every one, and the ones in production ship through EZPIPELINE, my own CI/CD server.
Open-source design studio
Open sourceknitted.studio
On-brand marketing graphics, for you and your AI model.
Local AI tooling
In developmentLLM Factory
Bake open-weight models into portable, OpenAI-compatible containers.
How this site ships
Shipped on my own stack.
This site is built, stored and served by software I wrote. Here is the path from my editor to your screen.
git push
A push to main on GitHub. That is the whole release process.
EZPIPELINE
My CI/CD server is watching the branch. It lints and typechecks the code, checks the colour contrast of both themes, then builds the site.
FileFreak SDK
The build asks FileFreak which photos each folder holds. All 18 photos on this site live in FileFreak storage, one folder per project, with 512, 1024 and 2048 pixel copies made by FileFreak.
FileFreak Sites
The pages deploy to FileFreak's edge. Only files that changed are uploaded, and any of the last ten deploys is one command away from a rollback.
Your browser
Each visit checks the photo folders again, so a swapped photo shows without a rebuild. FileFreak counts the visit with analytics it adds at the edge.

About
Hi, I'm Sean.
I'm a senior software engineer at Prudential, where I led the move of parts of the Prudential Express portal to a micro-frontend architecture. Before that I spent three years at Seisan Consulting, going from intern to technical lead on client apps across the web, mobile, games, and AR and VR.
On my own time I build products end to end. FileFreak started as a cloud drive in 2024 and grew into a developer platform: storage, static sites, git hosting and package registries under one account. EZPIPELINE, the CI/CD server I wrote to ship it, now ships my other products too, notch.fm and knitted.studio among them.
I like owning the whole thing: the design, the code on every layer, the infrastructure, and keeping it running once it ships. I studied Information Sciences and Technology at Penn State, and I live in Morristown, New Jersey.
