Founder and lead developer at ZappFlow, a UK-based software and automation agency building custom AI, data and workflow systems for businesses. I handle projects from initial scoping and architecture through to development, integrations, testing and deployment. Most of my work involves Python, JavaScript, APIs, browser automation, AI models and full-stack web development. Projects include an AI-powered trading system that processes Telegram signals, combines them with live technical market data and uses Claude for trade decision support, with a custom dashboard for monitoring results and decisions. I also built a BNG lead-generation system that monitors hundreds of UK council planning portals, extracts planning application data and documents, qualifies opportunities and pushes relevant leads into HubSpot. Other work includes a worker logistics platform that compares travel and accommodation costs while pulling live availability from Booking.com and Airbnb, and an automated influencer outreach system covering lead discovery, contact enrichment, outreach, follow-ups and a live management dashboard. I regularly build AI agents, RAG systems, web scrapers, browser automation, chatbots, custom CRMs, internal tools, client portals, workflow automations and API integrations. My stack includes Python, JavaScript, TypeScript, React, Next.js, Node.js, n8n, Zapier, Make, LangChain, OpenAI, Claude, ManyChat, GoHighLevel, HubSpot and MT4/MT5.
