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.
Chrome Extension · BYOK
Vision Browser Agent
Gives any vision-capable AI model real eyes and hands inside Chrome — its own virtual mouse, agentic loops, and full page control. An open alternative to Claude's Chrome extension, with an MCP bridge so CLI agents like Claude Code, OpenCode, and Antigravity can drive the browser.

Coding Harness · Rust
convigas-code
A terminal-native coding agent written in Rust. BYOK by design, with native browser use, sequential thinking, and built-in context retention & compaction for long sessions.

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.

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.
