Full-Stack Product
Beautiful, fast Next.js & React front-ends wired to real back-ends — auth, billing, realtime, and the unglamorous plumbing that makes them ship.
Currently CTO at Nexxy
Shayan AliSovereign Technologist
I design and ship production-grade products end to end — Next.js & React on the surface, Rust and hardened Linux underneath.

About
Sovereign means
owning the whole stack.
I'm Shayan — a full-stack engineer who refuses to stop at the browser. Pixel-perfect interfaces in Next.js and React, an agentic SaaS CRM running on a Debian VPS I administer myself, coding harnesses written in Rust, and language models I post-train for the job. Today I'm CTO at Nexxy, where I built the entire platform from first commit to production.
The throughline: control. BYOK architectures, self-hosted infrastructure, and systems that behave deterministically — so the people using them stay in charge.
Rust, For Real
Not a hobby language. I write agent harnesses, CLIs, and systems tooling in Rust when correctness, speed, and memory safety actually matter.
Linux Architecture
From hardened kernels to production VPS deployments on Debian. I own the metal my software runs on — no black-box PaaS in the way.
Agentic AI Systems
Vision-driven browser agents, MCP servers, voice AI receptionists, and custom post-trained LLMs — built BYOK, sovereign, and deterministic where it counts.
Selected Work
Things I've built
and actually shipped.
Products, tooling, and infrastructure spanning the browser, server, and operating system.
Post-trained LLM
Prometheus
A custom post-trained model based on GLM 4.6, tuned specifically for coding and agentic tool-use — tighter instruction following, cleaner diffs, fewer hallucinated APIs.

Agnes MCP & Skills
A drop-in MCP server and skill pack that lets agentic harnesses use Agnes image and video generation models, plus site-building skills, through a single tool interface.

Convigas OS
A Debian-based distro with a hardened kernel, GNOME & KDE Plasma variants, Wine pre-configured, and native Android apps through Waydroid — run anything, anywhere.

Websites & Landing Pages
Client Web Work
Modern, conversion-focused sites for US real-estate agents, a UK accounting firm, the getnexxy.com marketing site, and a collection of product landing pages.

Experience
Four companies.
One trajectory.
DevOps → full-stack → CTO. Each step added a layer of the stack I now own outright.
