Ship the thing you're trying to figure out.

I'm Josh. 20+ years in mechanical engineering and product development — including $10M manufacturing accounts at STIIIZY/Shryne and $1.4M+ in proprietary hardware sales through 3GRAMS™. The last few years I've layered on production software: algorithmic trading, iOS + BLE reverse engineering, public-data dashboards, Claude-driven agents, and security research.

I take contract work where the requirement is end-to-end shipping — backend, frontend, infra, hardware coordination — solo or embedded with your team.

What I've shipped

20+ yrs

Hardware product dev & manufacturing

Concept → CAD → prototyping → overseas manufacturing → commercialization. Led $10M manufacturing accounts at STIIIZY/Shryne; founded 3GRAMS™ and scaled it past $1.4M+ in proprietary hardware sales.

Live $

Production algorithmic trading on Binance.US

Multi-indicator fusion (RSI / EMA / BB / MACD / VWAP), ATR-adaptive TP/SL, OCO order management, kill-switch risk engine. Real money in micro-mode since April 2026.

iOS · BLE

Reverse-engineered a hardware BLE protocol from scratch

SwiftUI app + Mac Catalyst. Cracked Puffco's AeroFrame protocol (SHA-256 challenge-response over GATT) to build an independent controller. FaceID, voice commands, cinematic HUD. TestFlight-ready.

Tactical

Real-time defense dashboard demonstrator

2D radar canvas with 360° sweep, range rings, threat blips. Simulated F-35 / F-16 / Su-57 / J-20 / Gripen telemetry, pilot biometrics, three-tier engagement controls (lock / track / engage). WebSocket broadcast.

8,557

Tesla operating signals tracked daily

Public-data ETL: JSON → SQLite → Fly.io-deployed dashboard. Superchargers, FSD miles, NHTSA recalls, SEC EDGAR, Form 4, Velocity Index. Every number cites its source. Live →

5 bugs

Reproducible findings in Tesla's open-source Go code

Coverage-guided fuzzing (testing.F) + Semgrep static audit. Each finding shipped with a runnable reproducer and responsible-disclosure timeline.

Plus prediction-market trading infrastructure (Kalshi RSA-PSS auth · Polymarket EIP-712 CLOB · Kelly-sized risk engines), a Claude Code agent running inside a Tesla's browser, and an autonomous Instagram growth stack on Meta Graph API. See all the projects →

Long-term

Embedded Engineer

$150–250/hr · or $25–40K/mo

Dedicated AI engineer on your team. One-week trial first so we both get to know fit.

  • Full-time contract or fractional (2–3 days/week)
  • Claude Code workflows, agent architecture, production systems
  • Slack-embedded · your tools, your sprints
  • References on request

What I work on

Hardware product development

Concept through CAD, prototyping, overseas manufacturing (China factory partners), patent / trademark support, DFM. 20+ years of shipping physical product.

Claude Code & agent workflows

Production-ready agents with tool use, prompt caching, thinking, structured output. I run a Claude agent inside a moving Tesla — yours can ship to production from anywhere.

Algorithmic trading & financial systems

Live execution on Binance.US, Kalshi (RSA-PSS), Polymarket (EIP-712). Risk engines, kill-switches, OCO orders, Kelly sizing — credentials never logged.

Data pipelines & dashboards

Public-data aggregation, scheduled collectors, visualizations. Stack: Node / Express / SQLite / Fly.io / Globe.gl / D3. Source-cited numbers, no fluff.

iOS / mobile & BLE reverse engineering

SwiftUI + Mac Catalyst. Core Bluetooth GATT, SHA-256 challenge-response auth, FaceID, voice via SFSpeech. I've taken proprietary BLE protocols apart.

Security research

Coverage-guided fuzzing (Go testing.F), Semgrep with composed rulesets, govulncheck reachability, CI/CD posture audit. Disclosure-ready writeups.

Full-stack AI-native products

Backend, frontend, infra, content — solo end-to-end shipping. When your team is small and "just ship it" is the requirement.

Claude API migration & tuning

Moving from OpenAI → Claude, or upgrading Claude versions. Prompt caching, cache-hit analysis, cost optimization.

Technical writing

PSIRT-grade disclosure reports, engineering documentation, product-spec writing. I can ghost-write your engineering blog at publishable quality.

Ready to talk? So am I.

Quickest path is an email with what you're trying to build. I reply within one business day — usually same-day for inbounds that include a clear problem to solve.
