Most AI automations look great in a demo and quietly break in production. I build the ones that actually run your business, deployed in about a week and hardened from day one. I'm an AI automation engineer who turns slow, manual business processes into reliable systems that pay for themselves fast. Using Claude Code, MCP, and modern AI tooling, I ship working automations in days, not quarters, then lock them down so they survive real traffic, security reviews, and 2 AM edge cases. What I automate (and the payback that follows): Lead-to-cash workflows: intake, qualification, CRM sync, and follow-up that recover hours every week and stop deals slipping through the cracks. Document and data pipelines: contracts, invoices, reports, and records parsed, routed, and filed automatically with full audit trails. Internal ops and back-office: onboarding, ticket triage, reporting, and approvals wired together across the tools you already use. Custom AI agents: Claude-powered assistants and MCP integrations connected to your real systems, not a sandbox. How I work: 1. Scope call: we pin down the one process costing you the most time or money. 2. Build sprint (days, not months): I ship a working automation fast, with you reviewing progress along the way. 3. Harden and hand off: secrets management, least-privilege access, encryption, and a written runbook so it keeps running after I'm gone. 4. Live in about a week: most projects deliver measurable payback within the first week or two of going live. Why clients hire me over a cheaper option: speed and security usually come as a trade-off. I deliver both. Every build ships with non-root containers, isolated environments, secrets rotation (Vault or AWS Secrets Manager), and SOC 2, HIPAA, and GDPR-aligned practices baked in, so what works in week one still passes an audit in month six. Stacks: Claude Code, MCP, OpenAI, Gemini. AWS, GCP, Azure, DigitalOcean, on-prem. Docker, Tailscale, Cloudflare Tunnel, WireGuard. Best fit for: founders and ops or engineering leaders in legal, finance, healthcare, and compliance-bound SaaS who need automation that's fast to ship and safe to trust. A quick first step: message me the one process eating the most time in your week. I'll send back a short, no-obligation plan for automating it, usually within a couple of hours during business hours.

I build production systems that hold up under real load — platforms serving thousands of active users and processing hundreds of thousands of transactions daily. Over 8 years I've delivered full-stack applications and on-chain infrastructure for clients across the US, Europe, Mexico, and Australia. On the web, I architect with React/Next.js and Node.js/Express against MongoDB, with an emphasis on the parts that break at scale: authentication, dynamic role-based access control, transaction integrity, and API design that stays fast as data grows. On-chain, I work in Solidity/Hardhat — writing, testing, and deploying smart contracts, including a wallet-signed deployment architecture that keeps private keys out of the codebase entirely. Infrastructure runs on AWS, DigitalOcean, and Vercel. Recent work includes a high-volume transaction platform handling six-figure daily throughput, an AI-powered smart contract auditing SaaS built on Node.js and the OpenAI API, and multi-codebase products spanning a Node.js backend, Flutter mobile app, and React admin dashboard with granular permission systems. What you get: phased delivery with reviewable commits at each step, clear communication, and an engineer who designs for the failure cases — concurrency, security, and data consistency — not just the happy path. I specialize in complex builds where architecture is the difference between a system that scales and one that stalls. If you have a web or blockchain project that needs to be built to production standards the first time, send me a message and let's talk through it.

40+ AI employees deployed. 10 in my internal fleet. 30+ across 15 client production environments. 99.5% uptime over 12 months. They research leads, write outreach, publish content, run audits, monitor systems, and report back. Every day. Without supervision. Not chatbots. Employees that do work. A meta-agent on a single server dispatches tasks across my internal fleet, reviews output quality, and ships me one daily digest. The fleet handles a full sales pipeline (research → qualify → email → LinkedIn DMs), multi-platform content, SEO, job hunting, and proposal drafting. What I deploy: AI Sales Teams — Agents that research prospects, enrich with company intel, score against your ICP, then draft personalized cold emails and LinkedIn DMs. 5-touch drip sequences. Rate limiting. Pipeline tracking. Your human reps close. The AI does everything before that. AI Content Teams — Agents that research daily, draft platform-native content, run it through quality gates that catch AI slop, and publish on approval. I've built pipelines for LinkedIn API, X API v2, and Reddit with content rotation and topic cooldowns. AI Operations Staff — Health checks, data syncing, scheduled reports, system monitoring, compliance audits. They follow the process exactly, every time, and flag when something's off. Fleet Orchestration — When you have multiple AI employees, you need a manager. I build meta-agents that coordinate your fleet, dispatch work, evaluate output, and deliver a single daily digest of everything your AI workforce accomplished. Verticals shipped: tax firms (6-agent IRS forms / TaxDome / bookkeeping swarm), digital ad agencies (30+ accounts across Google Ads / GA4 / Meta / LinkedIn), DTC supplements (3-agent brand intelligence in UK / US / AU markets), home-services operators (CRM + SMS booking + browser automation), B2B SaaS dev teams, prediction markets, newsletters, lead generation. Why clients keep me on retainer: I operate, not just build. Most freelancers hand you a bot and disappear. I deploy on production infrastructure with health monitoring, auto-restart, secret management, and audit trails. I keep them running. I've done it for myself first. My own business runs on AI employees. Lead research, outreach, content, SEO, proposals. Every system I sell to clients, I've battle-tested on my own operations. I know what breaks. 40+ deployments taught me where agents fail: config coupling, context overflow, token expiry, rate limits, memory drift, browser session decay, OAuth refresh races. I've hit every failure mode and built recovery into the infrastructure. You're paying humans to do work that follows a process. I deploy AI employees that do it faster, cheaper, and without taking weekends off. Send a message with the repeating process you want owned. I'll tell you in 24 hours if it's a fit. 1.

You have one shot to launch it right. Every week of delay, every half-built feature, every developer who ghosts after delivery costs you users, money, and momentum. I make sure that does not happen ✅ 10+ years building production iOS and Android apps for fintech, crypto, AI, and Web3 companies ✅ Senior Flutter and React Native developer, cross-platform from architecture to App Store ✅ Top Rated on Upwork with $100K+ earned ✅ Real shipped products with active users on both stores right now What I built: ✔ Mobile Apps: Flutter (Dart) and React Native (TypeScript) for iOS and Android. Startup MVPs, production rewrites, cross-platform apps, real-time systems, offline-first architecture, App Store and Play Store deployment. No supervision needed, no handholding, no gaps. ✔ Fintech and Crypto: non-custodial crypto wallets, Stripe payment integration, in-app purchases, KYC and KYT flows, trading platforms, multi-chain mobile wallets, fiat to crypto flows, banking app architecture. ✔ AI-Powered Mobile Apps: OpenAI API and Claude API integrations, LangChain workflows, RAG pipelines, AI chatbots, conversational interfaces, AI agents, on-device inference, LLM-driven automation built directly into mobile products. ✔ Blockchain and Web3: Ethereum, Solana, XRP Ledger, Bitcoin. Solidity and Rust smart contracts, DeFi protocols, NFT marketplaces, DAO governance, RWA tokenization, WalletConnect, MetaMask, multi-sig flows, dApp frontends. ✔ Backend and Infrastructure: Node.js, NestJS, REST APIs, GraphQL, WebSockets, Firebase, MongoDB, PostgreSQL, AWS, Docker, CI/CD pipelines. I own the backend, too, so you do not need a separate hire. Most clients come to me because they need one developer who owns the entire product: mobile app, backend, integrations, blockchain layer, and deployment. No coordination overhead. No gaps between layers. One clear line of responsibility. If you are building a fintech app, crypto wallet, AI-powered mobile product, or Web3 platform, send me your project details. I will respond with a clear technical plan and honest timeline within a few hours.
