About

I'm drawn to the frontier — where the models keep getting more capable.

i'm an AI/ML Engineer at Ema, where i research and build the AutoBuilder/AutoPilot, our agent harness. my focus is on agent orchestration, autolearns, and evals.

i recently completed my Master of Science in Applied Computing at the University of Toronto, focusing on computer systems and large language models. previously i worked as a backend software developer at Kijiji, and as both a research and teaching assistant at U of T.

i'm drawn to the frontier: designing agentic systems that are reliable today and ready for what comes next, as models grow more capable and the work we hand them grows more ambitious.

outside of work i sing, play piano, play guitar, and lose to my friends at video games. i also love making and eating food. my recipes are where the home-cooked ones live.

Notes

notes, field observations, and half-formed ideas, published as they're ready.

subagent designs how coding agents delegate to other agents, and the three paradigms emerging right now: preset profiles, runtime construction, and dependency graphs. apr '26read why i use emdash running multiple coding agents in parallel without losing your mind in terminal tabs. local-first, open-source, provider-agnostic — and surprisingly, the product is just organization. apr '26read

more notes in the works. i'm slow but sincere — things land here only when i believe them.
