I fix it, build what's missing, and make sure it actually runs without me holding it together afterward. I work across the full stack - WordPress, Shopify, WooCommerce, React, Next.js, Node.js, Python, Laravel - and spend a lot of time connecting systems that weren't designed to talk to each other. APIs, webhooks, CRM workflows, Google Sheets automation, order syncs, payment setups. I build SaaS platforms, CMS-driven sites, and e-commerce stores from scratch or take over half-finished ones that need rescuing. I also build AI-powered tools: OpenAI integrations, chatbots, document Q&A systems, lead capture bots, and workflow automation that replaces repetitive manual work. On the mobile and game side, I've contributed backend infrastructure to Tarisland - a shipped multiplayer RPG - covering REST APIs, leaderboard systems, player data, and in-app purchases. I also build React Native mobile apps, from MVP to production, including game mechanics, real-time features, and app store delivery. Before writing a single line of code, I figure out where the highest risk is and tackle that first. The result is clean, maintainable work - not a fragile patch you'll need to explain to the next developer. If you have a deadline, a broken system, or a product idea that needs building from scratch, I can help.
