I started a voice-AI company in first year. We sold it while I was still in school.

Now I’m on Shopify’s Applied ML team, working on the agents that talk to shoppers.

Selected work

2023 to 2025, co-founder, exited
Call Fusion

Voice agents that called the leads mortgage and real-estate brokerages had already paid for, talked to them properly, and booked the appointment. Nobody had to pick up a phone. We sold it in 2025.

2026, Applied ML engineering intern
Shopify

The shopping agent people talk to inside the app. I work on the prompts behind it, and I spend most of my time proving whether a change actually helped instead of assuming it did.

2026, personal AI agent, open source
Hermes

An agent I built for myself that runs on a VPS. I talk to it from Telegram, it keeps my health log without me typing anything, and it finds and ranks the internships I end up applying to.

About

What I build with

For coding I’ve used most of the harnesses out there. Cursor for a long time, then Claude Code and Antigravity, and lately Pi and Herdr, where I spawn subagents and agent teams and mix models across them based on how much reasoning the task needs. On the backend side it’s RAG pipelines, prompt and context engineering, evals and judge rubrics, and guardrails to keep a model in bounds. For fun I run an autonomous agent on a VPS that I talk to from my phone, with its own skills, cron jobs and routines. I was also an Anthropic campus ambassador, running workshops on Claude Code, MCP servers, agentic workflows and prompt engineering.

Now

It’s fall 2026. I’m at Shopify through December, and I’m applying for winter and summer 2027 internships in the US. I moved somewhere a fourteen-minute walk from the office this term, which has done more for how often I actually make it to the gym than any amount of planning did.

I just got back from Peru, my first trip off the continent with friends. Outside of work I read a lot about startups that failed and not much about the ones that worked, mostly because the failures are the ones you can actually take something from.
