About

I'm Stan Angeloff — a hands-on engineer with 20+ years of building production systems. Based in Sofia, Bulgaria. I go deepest as a senior individual contributor — give me a hard problem and room to work, not a delivery board to manage. This blog is my personal space for thoughts, rants & research.

◆What I'm up to (2025—)

Most of my free time goes into Flemma — a low-level AI workspace that runs inside Neovim. Not a wrapper, the actual thing: streaming APIs, tool execution, prompt pipelines, talking to Anthropic, OpenAI and Google directly. I built it because I needed it for work — PRDs, statements of work, R&D spikes, client documentation. Every feature exists because a real problem demanded it.

The core belief: models come and go, but the workspace you build around them is yours. Go one level lower than you think you need to. Write your own agents, wire up your own tool execution, parse your own streaming responses. The best way to understand AI tooling is to build it yourself.

By day I'm CTO and hands-on architect at Luup — a white-label “Community Commerce” platform. The majority of the codebase is mine. I also set up the team's AI-agent engineering practices — review skills, production guardrails, the works — so the whole team can adopt LLMs safely.

I'm also experimenting with Voxize, a voice-to-text tool for Linux/Wayland — my daily driver for AI-assisted coding instead of reaching for the keyboard.

◆Technical background

I've been at this for over two decades, touching just about everything along the way. Some highlights from the day job:

Nuclear — built an operations platform for the Kozloduy nuclear power plant (2004 — .NET + AJAX before “AJAX” was coined)
Enterprise B2B — Saudi Aramco, the UK Post Office, Forever Living (£1M ARR) — a decade of SaaS platforms at PSP
Fraud & fintech — real-time affiliate-fraud detection at ~1M conversions/day; an immutable, double-entry accounting ledger on Postgres
Migrations — replatformed ~50 storefronts to Shopify Plus with zero prior experience; reverse-engineered ~100,000 lines of Zoho Deluge to retrofit an API over a legacy CRM

And from the open-source archives:

CoffeeScript — used to be a top 10 contributor to jashkenas/coffeescript (now sitting at #9, but who's counting)
PHP — past maintainer of php.vim, the de-facto Vim syntax for PHP (473+ stars) until Tree-sitter superseded it
JavaScript — built Zoey, a lightweight mobile app framework, and Lotte, headless browser testing with PhantomJS before Puppeteer existed
Ruby — built compass-magick and compass-canvas, dynamic image generation in pure Sass
Shell & terminal — a big believer in open, free, terminal-based tools. Built vagrant-shell-scripts back when provisioning VMs was the thing to do
GitOps — managed all my PCs with Ansible for years, even gave a talk about it back when Ansible was the underdog. Now I run NixOS

TypeScript, Node.js, and whatever else the job demands — I've never been one to stick to a single stack.

◆The honest bit

As you can tell, most of those OSS projects are pretty old. I haven't been as active in the community as I'd like — however, I'm still here, still tinkering, and Flemma is where that energy goes now.
