# Robert Vassallo > Builder shipping iOS apps and agentic systems. iOS apps on the App Store, multi-agent runtimes, and hackathon wins. Based in Leeds, UK. Currently a software engineering intern at Daisy (ag-tech startup backed by the Collison brothers, founders of Stripe), shipping agentic systems into production since June 2026. Building since age 12. ## Selected projects - ARGUS: a city-operations decision system running entirely on one NVIDIA DGX Spark. Ingests ~780 live traffic camera feeds, counts vehicles on-device with YOLO11x, and uses Nemotron 70B + RAPIDS to predict congestion cascades ~12 minutes ahead, then closes the loop from detection to operator-approved bus reroute to verified outcome. Built the UI, the human-in-the-loop decision flow, and the ElevenLabs voice agent with a long-term session-memory layer. 1st in the ElevenLabs Challenge at NVIDIA Hack for Impact, London 2026. - BiteSwipe: shipped iOS cooking app on the App Store (Flutter, Supabase). Swipe recipes, plan a week, auto-generate the shopping list. Funded by a £3k Spark grant. https://apps.apple.com/ie/app/biteswipe/id6759111945 - Open Ocean: real-time Tessendorf FFT ocean simulated in the browser (inverse-FFT heightfield, Jacobian-determinant foam, multi-point buoyancy). Three.js/WebGL on the GPU. Playable demo: https://roberthq.com/oceandemo - Concordia: live multi-agent Minecraft simulation running entirely in the browser (Node, mineflayer, Claude, BrowserPod). £250 prize at the AI in the Box hackathon. https://github.com/0-robert/Concordia - Pyarmor: cracked a commercial Python code-protector. Unpacked a PyInstaller app, patched CPython's marshal loader to dump the deobfuscated modules, then decompiled them back to source. Paid disclosure at age 15. - Ghostplot: agentic pipeline estimating embodied carbon of data centres (LangGraph, Claude, PyMC, ILP, Mapbox). 2nd place, UCL x PGIM. - Compound: closed-loop UX testing without users. A neural encoder (TRIBE v2) predicts brain response to any URL, Claude writes and applies DOM patches, then re-scores. https://github.com/0-robert/compound - Hot/Cold: Raspberry Pi haptic device guiding blind users toward objects (YOLOv8, MediaPipe). Built at an EF accessibility hackathon, tested by RNIB users. ## Links - Website: https://roberthq.com/ - GitHub: https://github.com/0-robert - LinkedIn: https://www.linkedin.com/in/robert-s-vassallo/ - Email: robert [at] roberthq [dot] com
