Your SaaS idea deserves more than a freelancer who disappears mid-build. I'm Troy, having over 10 years of experience building scalable apps, 100% job success, every time. Most clients come to me after a bad experience. A developer who promised the world went quiet after the deposit and left them with half-built code they can't maintain. I don't work that way. I build systems that scale. Web platforms, mobile apps, AI-powered tools, cloud infrastructure, I've done it across 100+ projects, and I stay accountable from kickoff to launch. Here's what I actually build: - Web and SaaS platforms using React, Next.js, Node.js, FastAPI, and Django. If you need a multi-tenant SaaS or a complex web app, this is my main lane. - AI and automation systems using OpenAI, LangChain, n8n, and Make. LLM integrations, AI agents, data pipelines. I've shipped them into production, not just prototyped them. - Mobile apps on React Native and Flutter, cross-platform and native iOS/Android. - Cloud and DevOps on AWS, GCP, and Azure with Docker, Kubernetes, and CI/CD pipelines that keep things running without babysitting. If you want someone to think about your architecture before writing a single line of code, someone who's been through the growth from MVP to scale, that's what I bring. I'm selective about the projects I take. That's why my job success is 100%. Want to talk through your project? Let's figure out if we're a fit.
