Ask about me

Nathan Espejo

3rd year (2026-27) in Software Engineering at Western University, graduating May 2028. Looking for a Summer 2027 software engineering or applied AI internship.

I'm a software engineer, and most of what I build lately is LLM tooling I actually use. I care about the boring parts too: tests in CI, data that syncs cleanly, changes I can roll back.

I'd rather pick a cheap model that does the job well than pay for the biggest one. In my homelab the model proposes a change and plain code applies it, with a log or a rollback behind it.

Right now: using Campus every day across my six courses, and running my homelab, where agents propose config changes and nothing applies until I approve it.

    Software Engineering Intern · TeraGo · Markham, ON

    Built a working outage-email parser: a local LLM on Ollama reads providers' non-standard outage emails and opens Jira issues. It works end to end, but TeraGo hasn't deployed it yet; they've started revisiting it. Also wrote Channel Finder, a Python tool that shortlists clear RF channels from MapInfo spectrum records, validated on 760 test cases, and deployed a Copilot Studio agent that answers engineers' RF questions.

    VP of Data/ML (promoted from Software Developer) · 3D Western · London, ON

    Started on the Dockerized print pipeline, then as VP co-led two data developers: a print-safety dataset of 2,559 clean renders from 4,620 scraped 3D models, rendered in Blender and checked by a VLM. The best small vision model agreed with those labels on 84.2% with the filename visible, and 76.9% from the image alone on the earlier prompt. Ran alongside my TeraGo internship.

Campus

Aug 2026 to nowsolo

My courses are spread across six Brightspace pages, so I built one place to check deadlines, study from slides and test a draft against the brief. Campus syncs everything into SQLite and answers from the course files with hybrid retrieval: a lexical prefilter, embeddings and a cross-encoder reranker. Its 20-tool agent logs every change it makes to my notes or due dates, and it runs on any OpenAI-compatible endpoint, local or hosted.

    My laptop and a home server built from used parts run from one NixOS flake. Hermes Agent, from Nous Research, proposes the config changes, but nothing applies until I approve it, and a failed build rolls back to the last good one. One bug I won't forget: I set a WireGuard VPN as the server's default route, the peer died, and the whole machine went dark until I reset it by hand. Now the VPN lives inside the one container that needs it.

    Jul 2026Hack the 6ix 2026solo

    Built solo at Hack the 6ix 2026. It watches a camera, listens for sounds and reads sensors, and you set automations in plain English, like "when glass breaks after 10pm, alert me." A 1B model turns that into a rule, plain code checks every rule each 500 ms, and vision, audio and the LLM all run on one $80 board with no cloud inference.

    Overall 3rd at Spark 2026, built with my team. We started from a winter storm that cut off a regional hospital and led to missed referrals and follow-ups. Patients check in by chat or voice, and providers get one timeline with risk signals pulled from those conversations.
