Principal Engineer / Hands-on CTO. 20+ years building SaaS platforms from 0 to 1 through to production. Currently architecting a Node.js, Next.js, PostgreSQL and GCP wallet-pass SaaS for a London startup. Before that, 10 years as hands-on CTO of a white-label live-streaming platform (thousands of concurrent users during peak events, bespoke billing, Web3 NFT-gated access) and 6 years leading the tracking pipeline at a global affiliate network (5M+ daily events, zero data loss). On the side I founded and still run an affiliate analytics SaaS, now 16 years old, with 100+ external API integrations and a zero-downtime TB-scale MySQL to PostgreSQL migration behind it. Strongest on backend architecture, audits of existing systems, scaling prototypes to production, and high-volume data and API ingestion. Comfortable parachuting into live codebases without disrupting what works. Node.js, TypeScript, Next.js, PHP, PostgreSQL, MySQL, Redis, AWS, GCP, Docker.

Most businesses take 4+ hours to respond to a new lead. The systems I build respond in under 60 seconds with personalization and automation every time. I build AI automation that makes small businesses money while they work: lead-response systems that text back instantly, missed-call text-back with AI reply handling, appointment reminders and win-back campaigns, and AI-written weekly KPI reports delivered to your inbox every Monday. Built on n8n, the Claude API, Twilio, and Stripe, running 24/7, monitored, no babysitting required. What I bring: 6+ years as a technology consultant delivering enterprise systems for Fortune 500 clients, requirements, build, UAT, rollout 4 iOS apps designed, built, and shipped to the App Store solo Full-stack development (MERN certificate, UT Austin) fast, modern websites and web apps with booking, forms, and payments integrated 5 years in product operations at a global fitness franchise HQ (1,500+ locations) plus I understand how service businesses actually run SEO, brand design, and AI image/video tooling to round out the build I work fast, communicate clearly, and deliver systems you can see working, every project ends with a walkthrough video and documentation, not a handoff mystery. If you're losing leads to slow replies, drowning in manual follow-up, or need an automation built right the first time: message me. I'll usually respond within a few hours with a concrete plan.

I am a Silicon Valley–based entrepreneur and full-stack developer with more than 10 years of experience building software, launching products, and solving operational problems. From 2016 to 2017, I served as a director at a development company that created and launched its own startups. My work covered the full product lifecycle—from market research and validation to software development and go-to-market strategy. I have also worked as an independent developer, both on and off Upwork, supporting a range of U.S. corporations. In 2026, if you're not using agentic automation effectively, you're tech stack is already obsolete. The competitive advantage is agentic operations: AI systems that can plan, use tools, complete multi-step tasks, coordinate with other agents, and escalate important decisions to people. I help businesses upgrade existing products, technology, and workflows to capture the full operational value of AI. I can build, modify, and refine agentic systems using Hermes, LangChain, and custom orchestration frameworks—including specialized agents, multi-agent workflows, and supervisor agents that manage other agents. Choose me when you need more than an AI demonstration. I combine AI architecture, full-stack development, product strategy, and UX/UI design to create practical systems that integrate with your existing operation and are built for real-world use. Key Use Cases * Rapid AI prototype and MVP deployment * Custom AI-enabled websites and mobile applications * Workflow and repetitive task automation * Multi-agent systems and supervisor agents * CRM, cloud data, project management, HR, and business system integrations * Automated Git repository triage, issue creation, documentation, and release workflows * AI chatbots, internal copilots, and customer support automation * Data extraction, classification, reporting, and decision support * Legacy application modernization with AI capabilities * Human-in-the-loop systems for review, approval, and oversight Core Skills AI: Agentic AI, AI Agents, Multi-Agent Systems, LangGraph, Hermes, LLM Orchestration, RAG, Prompt Engineering, Custom Model Training and Fine-Tuning Development: Node.js, JavaScript, PHP, SQL, REST APIs, Webhooks, SaaS Development, AWS, Database Architecture, Mobile Development. Automation: Workflow Automation, API Integration, CRM Integration, Git Automation, AI Chatbots, Business Process Automation Product: UX/UI Design, MVP Development, Product Strategy, Technical Architecture, Go-to-Market Strategy An NDA-protected client had customer requests, CRM updates, and internal tasks spread across disconnected systems, forcing employees to repeatedly copy information and manually coordinate follow-ups. I designed an agentic workflow that interpreted each request, updated the correct records, created and assigned tasks, and routed exceptions to the appropriate team member for review. The result was a faster and more reliable operating process with fewer repetitive tasks, smoother handoffs, and clear human control over important decisions. Send me the workflow, system, or product you want to improve. I will identify the highest-value opportunities for agentic automation and build a practical path from your current technology to a reliable, production-ready system.
