Eric Wang
About this gig
Need a SaaS product built fast, without the cost and overhead of a full team? You are in the right place.
I am a senior software engineer and studio lead with 25 years of experience, specializing in AI-driven development automation. At my studio, one engineer working with an AI co-pilot team ships production-grade products at the speed of a whole department. In a single year we delivered 14+ live products, taking some SaaS apps from zero to production in as little as 23 days.
WHAT I CAN BUILD FOR YOU:
Multi-tenant SaaS web applications from scratch. Secure authentication and authorization (OAuth2 / OIDC). Payment and subscription integration. REST and API integrations, including LLM and AI gateways. Legacy system modernization and tech-debt cleanup. CI/CD pipelines and cloud deployment on GCP Cloud Run and more.
MY CORE STACK:
.NET 8, Blazor, ASP.NET Core, FastAPI, Next.js, React, TypeScript, Node.js and more.
HOW I WORK:
Clear scope, fast iterations and direct communication with me, the engineer who builds it. No account managers, no hand-offs.
Message me first with your idea or problem. I will recommend the right scope and a realistic timeline before you order.

FAQ
Do I need to have all the technical requirements ready before ordering?
No. Just message me with your idea or problem and I will help you define the scope, recommend the right package, and give you a realistic timeline before you place an order.
Can you modernize or fix an existing application instead of building new?
Yes. I handle legacy modernization, tech-debt cleanup, performance and security improvements, and adding new features to existing codebases. The Basic audit package is a great low-risk way to start.
How fast can you deliver? Can you really launch in 23 days?
Yes. With my AI co-pilot workflow, a focused SaaS MVP can go from zero to live in as little as 23 days. Timelines depend on scope and integrations, but I deliver full-team speed. We agree on a realistic milestone plan before we start, so you always know what to expect.
What tech stack do you use, and is it production-grade?
I build with .NET 8, Blazor, FastAPI, Next.js and Google Cloud Run. Everything is production-grade: multi-tenant architecture, secure authentication (OAuth2/OIDC), LLM gateways and payment integration. You get clean, scalable, enterprise-ready code, not a throwaway prototype.
Do you speak Chinese? Can we communicate in Mandarin?
Absolutely. I'm a native Mandarin speaker based in Taiwan and also work fluently in English. Chinese-speaking founders and teams are very welcome, we can discuss requirements, architecture and updates in Mandarin, making complex SaaS projects smooth and clear.
