No history, no highlight reel — just the present tense. For the history, there's the CV.
01 / currently
Six-day weeks, on purpose.
Fractal Tech
Software engineering fellow — six-day weeks, thirteen-hour days, shipping real systems instead of studying them.
02 / building
Two systems, in parallel.
Nexus
A reading, notes, and AI workspace that turns highlights, notes, and chat into one shared resource graph, so a citation stays a live link back to its evidence instead of a dead excerpt. nexus.nielseriknandal.com
niels-gpt
A tiny, complete LLM system — tokenizer, cache, pretrain, SFT, kv-cache inference, chat CLI — built laptop-first with strict guardrails instead of borrowed magic. source on GitHub
03 / open to
The next hard problem.
Full-time AI / software engineering roles
Model internals, deterministic backends, or the interfaces that connect them — that range is where I do my best work.
04 / on this site
Never quite finished.
Dark mode
Landed recently, so this page reads fine at 1am too.
ctrl+k terminal
A keyboard launcher for getting around the site without reaching for the mouse.
/lab
Interactive model-internals experiments, starting with a token-sampling playground — temperature, top-k, and top-p you can actually feel. open the lab
