App Building Services — Katie Dickieson | Cornell M.Eng
App Building Services

I build apps.

Web apps, mobile, AI tools, dashboards, automations — whatever you need built, I engineer it. Cornell-trained. Full-stack. Already shipped products used by real people.

What I Build

If it runs on a screen,
I can build it.

From idea to deployed product. I handle the architecture, the code, the database, the deployment — and I build it to last.

🌐

Web Apps & Portals

Full-featured web applications with authentication, dashboards, user management, and real-time data. Built to scale.

📱

Mobile Apps

Cross-platform mobile apps that work on iOS and Android. Native feel, single codebase, deployed to app stores.

🤖

AI-Powered Tools

Fast, responsive, conversion-focused sites. From simple landing pages to full marketing sites with forms and payments.

How It Works

Four steps from idea to shipped product.

No bloated process. No months of meetings. You tell me what you need, I build it, you get a working product.

01

Submit your project

Fill out the intake form below. Tell me what you're building, your timeline, and your budget range. Takes 5 minutes.

02

Discovery call

We jump on a free 20-minute call. I ask the right questions, you describe the vision. I tell you if I'm the right fit.

03

Custom proposal

You get a detailed scope, timeline, and flat-rate quote within 48 hours. No hourly surprises. You know exactly what you're paying.

04

Build + ship

I build it. You get progress updates. We iterate together. When it's done, I deploy it and hand you the keys.

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.
Enterprise AI Workflows

I also build intelligent systems for companies at scale.

Not chatbots. Not generic AI wrappers. Purpose-built portals grounded in your real documentation, your real processes, and your real expertise.

"Your team's knowledge is trapped in spreadsheets, SharePoint sites, and one person's head. I build AI-powered portals that make it accessible, accurate, and impossible to lose."
◈

Grounded AI Agents

Conversational assistants that answer questions using your actual documentation. They cite sources, refuse to invent, and guide users step-by-step. Your subject-matter expert, available 24/7.

▦

Unified Portals

One connected experience replacing the sprawl. Forms, calculators, reference docs, and AI assistants in a single portal your team actually wants to use.

◆

Knowledge Capture

I interview your subject-matter experts, structure their knowledge into reusable data, and build systems that distribute it at scale. The expertise stays even when the expert moves on.

◤

Calculator & Form Automation

Replace disconnected Excel calculators with smart, guided workflows. Built-in validation, contextual help, and AI that nudges users when they're about to make a mistake.

◑

Compliance & Audit Prep

Turn dense rubrics and regulatory requirements into plain-language assistants. Your team understands what the auditor checks, what evidence they need, and how to prepare.

◊

Full IT Handoff

Every system comes with source code, documentation, and a step-by-step handoff so your internal team can own, modify, and extend it forever. No vendor lock-in.

Case Study

Global automotive manufacturer. 150,000+ employees. Internal operations spanning dozens of plants across multiple continents. Their portal was a network of disconnected forms, calculators, and SharePoint sites. Engineers bounced between them. New hires took hours of 1:1 training.
