My Portfolio
Research tools and AI agents — built to actually run in the real world.
Kroniqo
● ActiveAI agent that "ages" via a SQLite Consequence Graph with recency decay (e^−0.03×days). Multi-backend LLM routing across 7 providers, proactive outreach, sub-agent system, and a FastAPI analytics dashboard with Chart.js.
CircuitLens
● ResearchFull-stack mechanistic interpretability platform on TransformerLens + FastAPI + Next.js. Key findings: L11·H31 confirmed as Llama-3.2-1B's IOI name-mover head; parametric memory collapses from 98% → 1.6% under adversarial repetition.
Gattai
● ActiveUnified AI orchestration layer — combining specialised agents for seamless multi-task execution across complex, multi-step workflows. Designed for scenarios where single agents fall short.
