After 12+ years and 60+ projects, I've realised the work I'm proudest of isn't the fanciest tech stack. It's the businesses I genuinely helped grow. Seven years ago, a scrappy New Zealand startup brought me in to build their product. Today they operate in four countries. Did I write good code? Sure. But what I'm proud of is that I was there for every pivot, every growth challenge, and we even faced a pandemic together. That's how I work. I don't do quick one-off builds. I get invested. (My wife would say too invested. I've been known to answer client calls at odd hours when something urgent comes up.) I'm a full-stack engineer and technical lead, the person you bring in when you have an idea and need someone to architect and build the whole thing, or when an existing product needs to scale without breaking. And in an era where almost anyone can generate code, what actually matters is understanding your business and building toward where you want to be. That's the part I care about most. 🤝 What you're actually getting: → A developer who learns your business well enough to suggest improvements you haven't thought of → Someone who sticks around long enough to see your vision come to life → Code that won't break when you scale (I learned that one the hard way early on) → Outcomes, not hours. I'm building toward your goals, not a timesheet 📈 Partnership history: I've worked with some incredible teams over the years. An Australian company that went from a simple MVP to serving enterprise clients over our five-year partnership. A German business that trusted me to modernize their entire system without taking anything offline, done with zero downtime. After 60+ projects and a 100% Job Success Score, I've learned success isn't about the technology. It's about understanding what you're trying to achieve and being genuinely invested in getting you there. 🛠️ What I do day-to-day: 💻 Frontend: React, Next.js, Angular, Vue, TypeScript, React Native, Flutter ⚙️ Backend: Node.js, Python, Golang, Express, NestJS, Django, REST & GraphQL ☁️ Infrastructure: AWS, Google Cloud, Azure, MongoDB, PostgreSQL, CI/CD, Docker 🔌 Integrations: Stripe, PayPal, Xero, QuickBooks, social platforms, email services 🌟 Why clients stick around for years: I make their lives easier, not harder. I send updates before they ask for them, I think about their business problems while I'm writing code, and I build things their team can actually maintain after I'm done. I also move fast without cutting corners. Everything ships through proper review and testing, so speed never costs you reliability. And when something goes wrong (because something always does), I'm there to fix it. 🏆 Some wins I'm proud of: Last year I improved a client's system performance by 60% during a complete overhaul. Zero downtime, their users never knew we were rebuilding everything underneath. Another client was raising funding, and the technical demo I built ended up being key to securing their Series A. There's nothing quite like reading "the investors were blown away by the platform" in a thank-you email. ✨ You might be a good fit if: You're running a startup and need someone reliable for the long haul You're planning to scale internationally or transform digitally You're building a SaaS product that needs continuous development You're tired of developers who disappear after the first version 💡 What makes this different: I'll probably care about your business more than most employees do. When I take on a project, I'm thinking about where you want to be in a year, not just what you need built next month. When projects get complex, I pull in specialists I trust (frontend, mobile, DevOps), but you always work directly with me. No account managers, no miscommunication, no getting shuffled between team members. 📋 How I work: We start with your goals, not just the technical requirements, but what you're actually trying to achieve. Then we map out a plan that fits your timeline and budget, and development runs in weekly or bi-weekly cycles with regular check-ins. I've seen too many businesses get burned by developers who build something that technically works but doesn't solve the real problem, or that works at first and falls apart the moment you scale. That's not how I operate. When you succeed, I succeed. 💬 Want to chat about your project? I'd love to hear what you're building and see if we're a fit for a long-term partnership. Fair warning: I ask a lot of questions upfront, because I genuinely want to understand your business before I write a line of code. Twelve years in, seven-year client relationships, and still genuinely excited about building great software. Let's see what we can create together. Currently accepting new long-term partnerships 🚀
