Do you suspect assets are being hidden? Has your organization been digitally compromised? I am a specialized forensic analyst located in Dallas, Texas, focusing on Blockchain Tracing and Open Source Intelligence (OSINT). Unlike generalist investigators who rely on public databases, I utilize custom Python-based reconnaissance tools to uncover the "Digital Footprint" that suspects think they deleted. My Core Capabilities: * Cryptocurrency Tracing: Tracking Bitcoin, Ethereum, and Stablecoin movements across exchanges (Binance, Coinbase) and "Mixers." * Deep OSINT & Social Engineering: Locating hidden social media accounts (Sherlock), burner emails (Holehe), and leaked credentials on the Dark Web. * Corporate Due Diligence: Auditing companies for "Red Flags," shell entities, and executive vulnerabilities. * Cyber-Security Consulting: Preventing SIM-Swaps, securing 2FA protocols, and hardening corporate infrastructure. Who I Work With: * Private Investigators needing a "Cyber Arm" for complex fraud cases. * Legal Counsel requiring technical evidence for litigation. * Corporate Executives needing discretion and high-level asset protection. Why Hire Me: I combine "Street Smarts" (Language & Intelligence background) with "Code Smarts" (Python Automations). I don't just give you a list of links; I give you a verifiable Intelligence Dossier ready for your client or court. Languages: English, Russian, Uzbek (CIS Region Specialist). Let's find the truth.

𝐄𝐱𝐩𝐞𝐫𝐭-𝐕𝐞𝐭𝐭𝐞𝐝 (top 1% on Upwork) and 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬, with $𝟒𝟎𝟎𝐊+ earned across 𝟏𝟐𝟓+ projects. I'm a founder and full-stack engineer who acts as your technical partner, architecting AI and blockchain systems that work in production, not just in a demo. Most clients come to me when the build actually matters: when it has to be secure, has to scale, and has to handle real data or real money without breaking. I architect and build custom systems end to end, and I can bring in a vetted team when a project needs more hands. Think of me as a fractional CTO and a builder in one: senior judgment on the strategy, real hands on the code. A lot of AI talent stops at a clever prompt and a slick demo. I come at it as a systems engineer. I have architected a Layer 1 blockchain hardened with post-quantum cryptography, a decentralized exchange and validator platform, an on-chain tokenization system for commercial real estate, and production AI agents that run real sales and operations workflows. I work natively in fintech and regulated systems, so I'm as fluent in tokenomics, compliance, and data-heavy infrastructure as I am in the code itself. If your AI or your protocol has to be correct, not just impressive, that is the gap I fill. 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃 • AI agents and automation: multi-agent systems, LLM integration, RAG, and automation wired into your real tools and data • Custom full-stack software: React / Next.js, Node.js, Go, Rust, and databases, built and shipped end to end • Smart contracts and protocols (EVM and Solana): audited, gas-optimized, production-ready • DeFi and tokenization: staking, swaps, liquidity, governance, and real-world-asset / on-chain systems • AI for fintech and on-chain: the rare overlap of AI, blockchain, and financial systems, done by one person who understands all three • Technical strategy: architecture, security review, tokenomics, and the roadmap to get there 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐇𝐈𝐑𝐄 𝐌𝐄 • 𝐄𝐱𝐩𝐞𝐫𝐭-𝐕𝐞𝐭𝐭𝐞𝐝 and 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬: roughly the top 1% of Upwork talent, with $𝟒𝟎𝟎𝐊+ earned and 𝟏𝟐𝟓+ projects delivered • A founder's perspective: senior judgment on strategy, with real hands on the code • Security and correctness first: audits, hardening, and systems trusted to move real value • Senior, direct communication and predictable, on-time delivery If you are building an AI product or a custom platform, automating real operations, launching a protocol, or tokenizing real-world assets, and you want a technical partner who will get it right the first time, let's talk.
