Bryan G.

I build production-ready AI applications, SaaS platforms, marketplaces, internal tools, and workflow automation using Claude Code, OpenAI, Bubble io, Lovable, React, Next js, Supabase, PostgreSQL, n8n, Make, Stripe, and custom APIs. From MVPs to enterprise platforms, I focus on software that's built to scale and ready for real users. Over the past several years I've completed 100+ projects on Upwork, maintained a 95% Job Success Score, earned Top Rated status, and delivered over $300,000 in client work. My experience ranges from MVPs for first-time founders to large production systems handling payments, users, and complex business workflows.

Every phase ends with something working that you can test immediately. If I think there's a simpler, faster, or more cost-effective way to solve the problem, I'll tell you before writing code. Whether you're building an MVP, scaling an existing SaaS, integrating AI into your business, or replacing manual workflows with automation, my goal is to deliver software that's production-ready, not just a demo. Send me the problem, not the spec, and I'll help you map the fastest path to a working solution.
