Your Engineer

I'm Katie. I build things
that actually work.

Cornell-trained biomedical engineer turned full-stack developer. I've shipped apps used by real people — portals, dashboards, AI tools, mobile apps. I don't just write code. I engineer solutions that hold up under real use.

FAQ

Questions you probably have.

What tech stack do you use?
It depends on the project. I typically build with React, Next.js, Node.js, Supabase (Postgres), and deploy on Vercel or Netlify. For mobile, I use React Native or Swift. For AI features, I integrate Claude, OpenAI, or custom ML pipelines. I'll recommend the right stack for your specific needs.
How long does a typical project take?
Small projects (landing pages, simple tools) take 1–2 weeks. Medium projects (web apps with auth, dashboards) take 3–6 weeks. Complex builds (full platforms, mobile apps) take 2–3 months. You'll get a specific timeline in your custom proposal.
How much does it cost?
Every project gets a custom flat-rate quote based on scope and complexity. No hourly billing, no surprise invoices. You'll know exactly what you're paying before any work starts. Submit the intake form and I'll send you a detailed proposal.
What do I get when the project is done?
You get the complete source code, deployed and running application, documentation on how everything works, and a walkthrough call. It's your product — you own all of it. I can also set up ongoing maintenance if you need it.
Do you handle design too?
I build clean, functional UIs that look professional. For projects that need custom branding or complex visual design, I can work with your designer or recommend one. Most clients are happy with my design work — I build things that look good and work well.
What about revisions?
Two rounds of revisions are included in every project. We stay in close communication during the build so there are rarely surprises. If the scope changes significantly, I'll give you an updated quote before doing any additional work.
Who owns the code and IP?
You do. Once the project is complete and paid for, you own 100% of the code, designs, and intellectual property. Full transfer, no strings attached.
