## Experience

- Mave (https://maveai.co), full stack software engineer, May 2025 to August 2026, Toronto. Scaled customer onboarding 40x (4 to 160 concurrent users) through research pipeline optimization, AWS ECS/Fargate autoscaling and Django-Q task delegation, powering growth from 0 to 280 users and 1,000+ agents; earned a 4x contract extension (4 to 16 months). Architected a multi agent AI research system coordinating 4 concurrent agents (Perplexity, OpenAI, Grok) with timeout handling and cross agent aggregation. Built a 4 stage parallel inference pipeline (brand stories, content strategies, interest profiles, location intelligence) with 30 day marketing plans, HubSpot CRM sync and PDF delivery over S3 and email. Integrated 8+ external APIs (OpenAI, Perplexity, Google Places, HubSpot, Slack, Meta, Repliers MLS) into a multi tenant Django REST API with JWT auth, async Django-Q queues and Slack Block Kit notifications.
- Sliq (Harvard Business School), software engineer, May to September 2024, remote, three person team. Python scraping pipelines (BeautifulSoup, Selenium) for LinkedIn profiles, YouTube transcripts and SEC filings, with OpenAI sentiment analysis across them; shipped the product landing page in React.
- Auditorium AI (https://auditoriumai.ca), mentor, brand and web, 2026. Autonomous stage lighting out of Toronto; mentors the founders (he is not a cofounder) and rebuilt their brand and website.
- Tutoring: computer science, physics, functions and chemistry, through 2024.

## Projects

- TrickyClip (https://trickyclip.com): a $99 Windows app that finds the tricks in ski footage on the user's own NVIDIA GPU. V-JEPA 2 video embeddings, an EfficientAT audio tagger and 200 Hz GoPro IMU become a 4 Hz feature stream; a temporal model finds each run and five event types, and RF-DETR rider tracking refines takeoffs and landings at full frame rate. FastAPI and SQLite job worker, ONNX Runtime, NVENC frame accurate smart cuts, friends sort from their phones, and personal models retrain on each user's keeps and trashes.
- 2holl.is (https://2holl.is): an interactive timeline and historical archive for the artist 2hollis. A cinematic 3D intro that plays on scroll, a cylinder timeline of 605+ items with momentum scrolling, fuzzy search and community submissions through Supabase, and a full Web Audio engine (3 band EQ, reverb, delay, flanger, BPM and key detection, dual deck DJ mixing, local stem splitting). TypeScript, Three.js, GSAP, Cloudflare.
- Chem Place (https://chem.place): a lab notebook in the browser. Molecules drawn from SMILES, camera capture at the bench, a reagent library and an assistant that knows the project. SvelteKit, Cloudflare D1 and R2.
- hesh.ca (https://hesh.ca): a 7 ft by 24 ft backyard freestyle rail he built with his roommate over four weekends. It became a sponsored community rail jam; Red Bull and 60+ people came to the last one.
- Axis Visualizer (https://github.com/Milllr/axis-visualizer): a 3D explainer for off axis rotation in freestyle skiing. TypeScript, Three.js.
- Life: a personal life OS on Android, finance, health and the rest of a life in one local schema.
- ws: per branch git worktree workspaces for running parallel Claude Code sessions without agents clobbering each other.
- mllr.ca: this site. Vite, TypeScript, Three.js, GSAP and Lenis on Cloudflare Pages, with a first party analytics stack on Pages Functions and D1.
