Stephanie Gredell – Software Engineer & Freelance Developer for Web & App Projects

Hi, I'm Stephanie.

Startup MVP Builder & Freelance Developer

I help early-stage founders go from idea to MVP in 2–4 weeks — full-stack, fast, and ready for users, demos, or investors.

After 11 years at LinkedIn, I now work with startups to design and build production-quality MVPs, internal tools, and customer-facing platforms — fast, clean, and scalable.

Professional Background

After 11 years as a software engineer at LinkedIn, I now focus on helping startups build and launch MVPs quickly and reliably. I value clear communication, thoughtful design, and building software that solves real problems — not just add complexity. Whether you need a custom app, a polished website, or help getting an idea off the ground, I bring a calm, focused approach and years of experience to make it happen.

I take on projects starting at $2,000 based on scope and complexity. Ongoing development and support available by retainer. Smaller budget? Let's talk. I can help scope it accordingly.

Built a smart routing and resolution system for LinkedIn’s customer support chatbot. Helped reduce ticket volume by directing users to the right self-serve tools, personalized responses, or agents.
