I have no special talent. I am only passionately curious.

I build systems that run themselves.

AI-agent automation on the Anthropic and OpenAI APIs, live algorithmic trading, public data dashboards, and iOS + BLE reverse engineering — layered on 20+ years in hardware, from concept through manufacturing and commercialization. Shipped, running, verifiable.

Ten systems, arranged by capability.

Each one built end-to-end — backend, data integration, risk controls, UI. Not demos. Real infrastructure that trades real money, tracks real filings, ships to real users, and sells real products.

Behavioral-signal crypto trading engine

Production algorithmic trading on Binance.US. Multi-indicator fusion across RSI / EMA / BB / MACD / VWAP, ATR-adaptive TP/SL, OCO order management, Kelly-aware sizing. Kill-switch risk engine with daily-loss caps, per-loss cooldowns, rolling-drawdown lockouts, and credential-hygiene discipline (nothing logged). Live micro-mode real-money execution since April 2026.

Safe AI companion for kids — regulated-environment design

Per-child AI companion with parent-configured age bands (5–8, 9–12, 13–17) and a three-layer safety stack: homoglyph-normalized regex classifier → Claude-Haiku LLM input classifier → output verifier with fail-closed crisis fallback. PBKDF2-SHA256 parent PIN, per-profile rate limiting, alert dedup, sanitized error paths. Designed from day one around COPPA + state minor-safety law — same regulated-environment mindset that translates to ITAR / AS9100 work.

Personal AI agent & second-brain knowledge system

The agentic layer that runs everything else on this page: a personal AI agent on the Claude Agent SDK with multi-step tool use, sub-agent orchestration, structured outputs, and a persistent file-based memory — paired with an Obsidian second brain (PARA method) that documents every system I ship. Research, workflow automation, code, filings, and reporting, driven through one agent stack across the Anthropic and OpenAI APIs.

Public Tesla operating-signals dashboard

Open-source data dashboard tracking Tesla execution across 20+ signal trackers. Live feeds: NHTSA recalls, SEC EDGAR filings, Elon Form 4 holdings parsed from live XML, market data, the Supercharger network, and a VIN decoder — plus seeded historical trackers (deliveries, FCC) and a composite 0–100 Velocity Index. Every live number cites its source. Shipped as 35 commits in a single 4.5-hour session.

Kalshi + Polymarket signal-intelligence infrastructure

Twin research systems testing whether behavioral signals produce real edge on event markets. Kalshi (CFTC-regulated): scans ~11,000 live markets per cycle, RSA-PSS + SHA-256 signed auth with keys held in closure, weather markets cross-referenced against live NOAA GFS forecasts, 0–100 confidence scoring. Polymarket: Gamma API, Kelly-sized paper positions, per-signal-slot isolation, 1,600+ positions tracked, EIP-712 CLOB order specs scaffolded. Both dry-run by default with double-locked live executors.

Aerospace tactical dashboard

Real-time tactical dashboard demonstrator for aerospace & defense. 2D radar canvas with 360° sweep, range rings, and threat blips. Simulated fighter telemetry across F-35, F-16, Su-57, J-20, and Gripen platforms with pilot biometric monitoring (heart rate, stress, alertness). Threat-archetype profiling layer and three-tier engagement controls (lock / track / engage) for human-operator decision support. WebSocket broadcast, Apple-design frontend.

Independent BLE controller for Puffco hardware

Native iOS + Mac Catalyst app built in SwiftUI. Reverse-engineered the AeroFrame BLE protocol (SHA-256 challenge-response over GATT) to build a fully independent controller for the Puffco Peak Pro / Proxy / Opal line. FaceID lock, voice commands via SFSpeech, background BLE mode, cinematic HUD with telemetry strip and concentric rings. TestFlight-ready, bundle io.pyra.blecontroller.

About

Builder. Operator. Shipper.

I've been building hardware for 20+ years. Concept through CAD, through prototyping, through overseas manufacturing and commercialization. Founded 3G Global Holdings & 3GRAMS™ in 2019 and scaled it past $1.4M in sales on proprietary product design. Before that — and during — I led product development at STIIIZY / Shryne Group, managing $10M+ manufacturing accounts at a $1.6B company, with factory partners in China and patent / trademark support on the IP side.

The last few years I've layered on software and AI. Most of what's on this site is live — executing real orders, polling real APIs, writing to real logs. Full-stack across Node.js, SwiftUI, Next.js, Python. I built autonomous AI agent and sub-agent systems to automate workflows and accelerate execution, which is the thread that connects the hardware and software work.

I like problems at the edges: design for manufacturability and reverse engineering to avoid IP conflict; BLE protocol reverse engineering with SHA-256 challenge-response for PYRA; cryptographic auth (RSA-PSS signed Kalshi, EIP-712 for Polymarket); data provenance (if a number shows on my dashboard I can point you to the filing it came from); and adversarial safety (every "live" flag on my trading code is double-locked and logs zero credentials).

I ship fast. TeslaPulse — whole app, 20+ trackers, mobile audit — was 35 commits in a single 4.5-hour sitting. Right now I'm focused on AI engineering — agents, LLM orchestration, and the data systems around them — with a long-term pull toward aerospace & defense, where mechanical design, performance, and software converge.
