Experience
Independent Cybersecurity & Security Researcher
Independent vulnerability research spanning application security (AppSec), API and cloud attack surfaces, and smart-contract execution environments. Apply 10+ years of production engineering experience to threat modeling, exploitability assessment, and responsible disclosure.
- Earned numerous paid bug bounties through independent vulnerability discovery and responsible disclosure; research includes Amazon Web Services (AWS), Asurion, and other enterprise programs.
- Disclosed a production web-application vulnerability validated by a billion-dollar technology company's security team, receiving formal recognition from its CISO.
- Received public AWS credit for CVE-2026-18953, a high-severity path-traversal vulnerability in AWS Transform MCP Server (CVSS 3.1: 8.6), remediated in version 0.1.5.
- Perform security code review and abuse-case analysis of authentication and authorization controls, injection defenses, input-validation boundaries, and secrets management.
- Evaluate smart-contract and autonomous-agent security invariants: mandate-scoped authorization, replay-resistant sequencing, budget enforcement, atomic settlement, and fail-closed execution.
- Apply adversarial testing and failure-mode analysis to unauthorized invocation, replay, redirect handling, RPC outages, persistence failures, and upgrade risk; document exploitability and technical security judgments for responsible disclosure.
Solutions Architect in AI & Blockchain
Lead developer and sole author of the codebase for REAPP, a mandate-enforced agent payment protocol on Stellar.
- Led Soroban smart contract implementation and x402/Stellar integration for simple and composite MandateRegistry contracts enforcing authorization, merchant and asset scope, budgets, expiry, replay-resistant sequencing, and atomic token transfers
- Shipped source-verified Stellar testnet contract releases with deterministic builds, WASM hashes, pause and admin controls, and timelocked same-address upgrades that preserve contract IDs and storage
- Built and published the TypeScript developer stack: @reapp-sdk/core, @reapp-sdk/stellar, @reapp-sdk/ap2, @reapp-sdk/express-middleware, and reapp-protocol-cli
- Implemented signed AP2 mandate validation and fail-closed HTTP payment delivery with authenticated challenges, independent settlement verification, atomic fulfillment, immutable-result replay, and crash-safe no-second-payment recovery
- Developed live consumer and fulfillment reference agents plus interactive Express, AP2, and CLI testnet workbenches demonstrating successful purchases and contract-enforced rejection after mandate budget exhaustion
- Created 20 deterministic hackathon starter projects with reproducible archives, SHA-256 manifests, beginner-ready setup flows, and scenario-specific payment safety checks
- Published REAPP NETWORK, a 50-page, source-backed field guide covering the architecture, protocols, authorization, security, implementation, and merchant-readiness requirements of agentic payments
- Established threat models, failure drills, adversarial tests, and continuous gate checks covering unauthorized callers and upgrades, overspend, expiry, replay, redirects, RPC outages, and store failures
