Full-Stack Product
Fast, good-looking Next.js and React front ends wired to real back ends: auth, billing, realtime, and the unglamorous plumbing that makes a product actually ship.
Currently CTO at Nexxy
Shayan AliSovereign Technologist
I build products from the first commit to launch. Next.js and React up front, Rust and hardened Linux underneath.

About
Sovereign means
owning the whole stack.
I'm Shayan, a full-stack engineer who doesn't stop at the browser. I build interfaces in Next.js and React, run a SaaS CRM on a Debian server I look after myself, write coding tools in Rust, and post-train language models for specific jobs. Right now I'm the CTO at Nexxy, where I built the entire platform from first commit to production.
The common thread is control. Bring-your-own-key setups, self-hosted infrastructure, and software that behaves predictably, so the people using it stay in charge.
Rust, For Real
Rust isn't a hobby for me. I write agents, CLIs, and systems tools in it when correctness, speed, and memory safety actually matter.
Linux Architecture
From hardened kernels to production Debian servers. I own the machines my software runs on, with no black-box PaaS standing in between.
AI Agents
Browser agents that can see the page, MCP servers, voice AI receptionists, and custom post-trained models. Built to run on your keys and your infrastructure.
Selected Work
Things I've built
and actually shipped.
A mix of products, tools, and infrastructure, from the browser all the way down to the operating system.
Post-trained LLM
Prometheus
A custom post-trained model based on GLM 4.6, tuned for coding and tool use. It follows instructions more closely, writes cleaner diffs, and invents fewer APIs that don't exist.

Open Higgsfield Alternative
Agnes MCP & Skills
A drop-in MCP server and skill pack that gives coding agents access to Agnes image and video generation models, plus site-building skills, all through one tool interface.

Hardened Universal LinuxArchived
Convigas OS
A Debian-based distro with a hardened kernel, GNOME and KDE Plasma editions, Wine set up out of the box, and Android apps running natively through Waydroid. It runs pretty much anything, anywhere.

Experience
Four companies.
One trajectory.
I went from DevOps to full-stack developer to CTO, and each step added another layer of the stack I now own myself.

Let's build something
that runs on your terms.
A full product, a Rust tool, an AI agent, or the Linux server underneath it all. If it needs to go from idea to production, I can take it there.
