About

Τα αγαθά κόποις κτώνται
“Good things are acquired through toil.” — Socrates

My grandma instilled this principle in me, and I have always strived to embody it. I apply it to everything, from building my own products and projects to athletic pursuits and building meaningful relationships. I always strive to do what I can, while I can.

I study Computer Science at the University of Toronto and work as a Quantitative Researcher at The Quantitative Finance Club, and at UTMIST and UTBIOME as a Machine Learning Engineer. Outside of work: rugby, lifting, and reading. See my hobbies ↘

What I'm exploring

  • Agent swarms
  • ML for markets & healthcare
  • Building human-focused products

Pathology Foundation-Model Fusion screenshot

A weakly supervised pathology pipeline that runs 368,250 tiles from 203 whole-slide images through three foundation models (UNI2-h, Virchow2, Phikon-v2) and classifies seven lung adenocarcinoma growth patterns with attention-based multiple-instance learning. Agent-selected fusion strategies reached 0.874 macro-AUROC on a one-time test set of 41 patients.

Python · PyTorch · Hugging Face · scikit-learn · W&B

A group-safety platform whose Hono/MongoDB API runs check-in deadlines and alert escalation server-side, so incidents keep progressing even when phones disconnect. 12 merged PRs in 36 hours: consent-checked location sharing, hash-chained incident timelines, and voice-agent APIs, backed by a 169-test suite.

TypeScript · Node.js · Hono · MongoDB · Railway

A Next.js tool that compares an agent's plans with and without memory, surfaces field-level differences, and flags likely memory influence before anything executes. After a 40-scenario benchmark exposed retrieval failures, a redesign raised regression correctness from 2.5% to 95%.

Hobbies

Rugby

Rugby

During my short career on the Varsity Rugby team I played as a right winger, and, on occasion, blindside flanker (scrum in the photo). As my first contact sport, it taught me resilience and endurance.

Kickboxing + BJJ

Kickboxing + BJJ @ The Academy

I started both kickboxing and BJJ in June 2026 after years of being a dedicated UFC fan (Volk is my GOAT). It's been an important part of my discipline and athletic growth.
