• Solo-built and shipped end-to-end: Architecture, multimodal AI pipeline, 11-language localization, App Store/Play release operations, and unit economics.
• Beyond database hits: Low-latency Gemini vision pipeline recognizes real-world uncurated meals (dal, jollof rice, pho, regional mixed dishes).
• Feature suite: Barcode scanning, voice logging, 20+ micronutrient analytics, Apple Health / Health Connect sync, fasting timers, hydration tracking, and streak mechanics.
• Economics & Reliability: Local perceptual image hash (pHash) cache cuts recurring API costs by 42% (<240ms cached lookup); holds a 4.9/5 rating on the App Store.

• Cryptographic local storage: Core health logs encrypted on-device (AES-256 GCM SQLite) with FaceID/TouchID protection. No account required for core tracking.
• Explicit data boundaries: Optional Firebase backup and cloud AI insights require explicit per-feature opt-in; users retain total data deletion and local export control.
• Condition-specific journeys: 9 distinct clinical journeys (cycles, PCOS, fertility, pregnancy, perimenopause, endometriosis, PMDD, birth control, adolescent health) with 100+ clinical symptom inputs.
• Clinical export: Secure doctor-share PDF generation and Apple HealthKit / Android Health Connect integration.

Python 3.12 · FastAPI · Next.js 15 · LangGraph · Shannon Entropy · Dual-Transport MCP

• Workflow-Mining Pipeline: Ingests unstructured Slack, WhatsApp, email, and call transcripts, extracts organizational activities via Bayesian parsing, and constructs directed process graphs.
• Graph Entropy Scoring: Formulates an Automation Potential Score (APS) using transition entropy to pinpoint operational bottlenecks, then runs 1,000-event pre-deployment Monte Carlo simulations.
• Self-Deploying State Machines: Automatically compiles typed LangGraph state machines with Human-in-the-Loop review gates.
• Dual MCP Support: Ships stdio and Streamable-HTTP (POST /mcp) transports compatible with Claude Code, Cursor, and Codex CLI. Evaluated across 158 multi-turn interaction runs across 8 enterprise departments.

TypeScript 5.7 · Model Context Protocol · SceneDoc Format · Kimodo.cpp Diffusion

• 64 MCP Tools & 230+ Tests: Plugs into Cursor, Claude Code, or Codex CLI to turn existing codebases into animated, living products without rewrites or proprietary runtimes.
• Framework-Native Diff Staging: Scans routes and component trees, models interactive state machines, compiles open SceneDoc specifications, and generates native code for React, React Native, Flutter, Unity, and Three.js/R3F.
• 3D Diffusion Bridge: Features natural-language text-to-3D skeletal animation diffusion across 22 SMPL-X standard joints with retargeting for Mixamo and Unity Mecanim.

Zero-lang Primitives · Node.js / ESM SDK · MCP-Native Contracts · OWASP Agentic Top 10

• Contract-First Agent Execution: Deterministic JSON-only outputs, stable machine-readable error codes, schema validation, idempotent writes, and auditable receipts so agents never hallucinate text execution branches.
• Core Primitives:
  • @heros/agentic: Installable SDK surface for explicit, authenticated, auditable agent website actions.
  • forge: Agent-safe database migration risk gate scoring schema modifications before execution.
  • ledger: Accounting receipt primitive with idempotency keys to prevent duplicate actions.

Next.js 14 · TypeScript · Gemini Computer Use · Server-Sent Events (SSE) · RBAC

• Autonomous Audit Automation (Prototype): Demonstrates autonomous agents continuously inspecting compliance controls across AWS, GitHub, and Okta via Gemini Computer Use workflows.
• Zero-Cloud Demo Architecture: Runs on simulated AWS telemetry and in-memory audit logs for zero-dependency local evaluation and immediate reviewer verification.
