AI Solutions & Automation Engineer · Denver, CO

I build AI systems that take busywork off real teams.

I'm a full-stack engineer who turns messy, manual workflows into software people actually use: AI agents, automations, and internal tools, from first conversation to production.

See my workLet's talk

Open to full-time AI Solutions, Forward Deployed, and AI Automation roles, plus select contract projects.

What I build

I start with the problem, not the tool. I pick whatever stack fits and build what actually fixes it.

  • AI agents and assistants

    that answer questions, handle requests, and work from your own data.

  • Automations

    that move work between your systems, so nobody copies and pastes all day.

  • Portals and internal tools

    that give your team and clients one place to get things done.

  • Full products

    taken from rough idea to live in production.

Selected work

Real problems, shipped solutions.

Client work

AI chat platform for the healthcare industry

The problem
Teams needed fast, accurate answers from a large library of documents, plus the files they work with every day.
What I built
A multi-tenant SaaS AI chat platform with two retrieval pipelines. One searches a shared knowledge base of 100+ documents across every chat. The other lets users upload their own files, kept either for one chat or until they delete them.
Result
[Add one outcome, e.g. number of users, time saved, or questions answered]
  • React
  • TypeScript
  • Supabase (pgvector)
  • n8n
  • OpenAI
Client work

Client portal for a family office firm

The problem
A family office management firm needed a private, organized place to share documents and talk with clients.
What I built
A secure client portal with passwordless magic link login, a document vault, and async messaging.
Result
Delivered on a fixed-scope contract. [Add a short client quote if you can get one]
  • Lovable
  • Supabase
Portfolio build

Copperpeak Electric, field service platform

The problem
Small trade businesses juggle scheduling, dispatch, quotes, and invoices across texts, paper, and spreadsheets.
What I built
An end-to-end field service platform for an electrical contractor: scheduling, technician dispatch, quotes with e-signature, invoicing, and online payment.
  • TanStack Start
  • TypeScript
  • Supabase
  • Vercel
  • n8n

Client work

Outbound prospecting pipeline

The problem
Finding and researching prospects by hand was taking 10+ hours a week.
What I built
An automated pipeline that finds, enriches, and organizes 20+ qualified prospects per run, with email domain authentication (SPF, DKIM, DMARC) set up for sending.
Result
10+ hours of manual research replaced per cycle.
  • n8n
  • Apify
In progress

Membership system for a professional association

The problem
An association with 180+ members ran everything on paper and lost track of who was active.
What I'm building
A member directory site, online signup and payment, automatic member cards, annual renewal reminders, and a live sync to the owner's Google Sheet.

How I work

I work like an engineer embedded in your team, not a vendor throwing code over the wall.

  1. 1

    Listen first.

    I sit with the people doing the work and learn where the time actually goes.

  2. 2

    Map the workflow.

    I sketch the process, the data, and the handoffs before writing any code.

  3. 3

    Build and ship fast.

    Working versions early, real feedback often, no six-month surprises.

  4. 4

    Hand off cleanly.

    Documentation and a walkthrough, so your team owns what I built.

Technology should free people from busywork, never replace them.

Portrait of Raquel Pfeifle, AI Solutions and Automation Engineer

About

Hi, I'm Raquel.

I'm a full-stack engineer based in the Denver area. I grew up in Brazil, trained as a software engineer at Hackbright Academy, and I'm now finishing a B.S. in Computer Science at Southern New Hampshire University.

These days I focus on AI: building agents, automations, and tools for healthcare, financial services, and local service businesses. I like the messy part, where the process is unclear and nobody has written it down yet. That's usually where the biggest wins hide.

I'm a member of Anthropic's Claude Partner Network, and I speak Portuguese natively and Spanish comfortably, which helps when teams and customers don't all speak English.
