feds01 - Overview

Hi 👋 I'm Alex!

✨ About me

I am a senior product engineer at @userledio based in the UK. I'm passionate about infrastructure, developer experience, system design, and agentic technologies — building tools and systems that make engineering more sustainable, safe, and fun. In my spare time, I'm building Hash — a programming language and tooling ecosystem.

🔭 I'm currently working on

Hash programming language
Graphika A toy graphing library written in pure . Functioning as a alternative to Chart.js and charting/graphing libraries.
Durachok - A online web-based game for playing Durak, a popular Russian card game. Built with + , including some cool libraries: @tanstack/router, @tanstack/react-query, socket.io.
Bracketlint - A simple HTML/Django linter for checking the correctness of brackets in HTML files, written in .
teamsearch - A tool to look for and in files via CODEOWNERS, written in .

🧰 Developer experience tooling

At work, I've built internal tools to improve developer workflows:

bracketlint and teamsearch originated from DX work at Kraken Technologies
Infrastructure, CI/CD pipelines, and analytics systems at Userled
Cataloguing, contracts, and order management systems at Kraken Technologies

🌱 I'm currently exploring

Agentic technologies - LLM-powered agents, tool use, and autonomous workflows (Vercel AI SDK, Mastra)
Vector databases - Embeddings, similarity search, and RAG pipelines
Infrastructure as code - Terraform, CI/CD design, and cloud-native patterns
