Jayden Williams

I build AI products and then work out how to sell them.

Information Science student at the University of Maryland, cybersecurity minor, graduating May 2027.

I run Tessaly, my web design studio, and I build the tools behind it: an AI video studio whose agents post for brands I run, and a desktop AI coding agent. I train in outbound sales at SWORD SDR School. Based in the DC area.

Work

ContentFarm

TypeScript, Node.js (Fastify), SQLite, React, Tauri, Python · local models on one RTX 3090

A local AI video studio. AI agents research topics, write the scripts, render the pictures and voice, review the finished videos and post them to Instagram, TikTok and YouTube for brands I run.

  • In its first 9 days it ran 278 topics through the pipeline, rendered 940 videos and checked 573 of them with a local vision model before anything was queued.
  • The hard part was deciding what the agents may touch. They post through browser sessions I log in to myself, and nothing goes live until two separate switches are on.
  • The whole studio is exposed as MCP tools, so an AI agent can drive it. Pictures come from real screen recordings, rendered screens, motion graphics and procedural 3D, not only AI stills.

Rosalena

Node.js, Electron, Cloudflare Pages and D1, GitHub Actions

A desktop AI coding agent for Windows and macOS that runs local and free cloud models through one router, falling back to the next model when one is busy or rate limited.

  • 890+ automated engine tests and 160+ site tests, with a pipeline that builds, checksums and publishes every release.
  • An in-app updater that checks each download's SHA-256 before installing. 4 releases in 3 days.
  • Early-access telemetry on Cloudflare D1 that tracks installs, token use and model errors while keeping local-model conversations private.

Tessaly

My web design studio · custom websites for businesses of every size

I design and build the sites, and I find the clients myself by cold call, opening with a free website audit.

  • Contracted by the San Francisco Black Economic Chamber of Commerce (SFBECC) to redesign and launch its website. Its new landing page, in four languages, has been live at sfbecc.org since September 2026.

GuardMyData Live

Self-funded data-protection SaaS · since 2024

I took it from concept to payment flow, owning pricing, positioning and the customer journey end to end.

  • First $200 MRR with no ad spend: organic outreach, a free data-risk checker as the lead magnet and a 14-day free trial with no card required.
  • Still live. Since October 2026 I've put my time into Tessaly instead of growing it.

Also on GitHub: Controller Hub, a Windows app in Rust that turns PlayStation controllers into virtual Xbox ones (66 Rust tests, 39 UI tests in CI), and SizeLens, which shows folder sizes in File Explorer.
