Eric Le

Welcome to my corner of the internet.

About me

I was born in Vietnam and came to Sweden in 2006, when I was six. I grew up in Värnamo before moving to Gothenburg.

Outside work I listen to a lot of music and have played guitar since I was twelve. I once spent over 4,000 hours listening to music in a year. Otherwise I try to get some calisthenics in or play tennis and badminton.

Most summers I travel, lately London, Copenhagen, Prague, and Hanoi.

Experience

I build the layer between a language model and the job it has to do.

In practice that means agents, the developer tooling around them, and the full-stack work of making either usable by someone else. Some of that was paid work, eighteen months of it at Volvo Technology, and the rest is my own. I came to it from engineering physics and complex adaptive systems at Chalmers.

I spend most of my working day with coding agents, and the tooling I build comes out of that. When the same rules kept drifting out of sync across my projects, that became a CLI. When staging files for a prompt got tedious, that became an extension.

Where that happened

  1. jan 2026 to present

    shipping independently, open to the next thing

  2. jun to dec 2025

    working out what to build

    Took the time to learn TypeScript and web application development, and to work out where to point AI next.

  3. jan 2024 to jun 2025

    volvo technology, gothenburg

    The job was an agent that let engineering teams plot and query truck data by asking in plain language.

    It started as my master’s thesis and became a multi-step SQL pipeline with session memory.

  4. jun to aug 2023

    internship at bac ha software, hanoi

    Reproduced published GAN architectures in TensorFlow for image inpainting and pre-trained them on GPU.

  5. sep 2022 to jun 2024

    msc in complex adaptive systems, chalmers

    How simple agents and their environment produce behavior nobody designed.

  6. sep 2019 to jun 2022

    bsc in engineering physics, chalmers

    Where the modelling habits came from, before any of this was software.

Projects

Some of these solved a problem for me first and other people second. Each one has a page here on why it exists and how it works.

aitk — terminal transcript of the install command running in a project

aitk

CLI that installs one set of agent rules, skills, and standards into every project and keeps them in step. Installs from npm as @erclx/aitk and as a Claude Code plugin.

Jobtriage, chat interface with retrieved ad cards on a React Flow canvas

Jobtriage

Live agent that triages Swedish job ads against a profile. Reachable at jobtriage.erclx.dev without a key, and the case study carries the retrieval numbers.

Caret — chat input showing a trigger-character palette of saved prompts

Caret

Chrome extension that saves prompts and drops them into Claude, Gemini, and ChatGPT from the chat input. Live on the Chrome Web Store.

diction — a scored passage reading, with the word thought flagged and the th correction shown

diction

Pronunciation trainer that scores each sound against what a native speaker actually sounds like, and reports how often it is wrong. Runs offline with nothing leaving the machine.
