Case 1 of 4
Representative clinical AI assistant interface

PROJECT / 01Representative interface

35%lower response latency

Healthcare AI platform

Clinical AI, built to operate at scale.

Led the architecture and delivery of an enterprise platform connecting agent workflows, retrieval, voice, and operational automation.

The challenge

Clinical workflows required grounded answers, secure enterprise integrations, and responsive experiences for thousands of users.

What I built

Designed supervisor-based orchestration and specialized agents with LangGraph and MCP. Built asynchronous FastAPI services with streaming, caching, and evaluation.

  • Python
  • FastAPI
  • LangGraph
  • MCP
  • AWS
Representative AI model orchestration interface

PROJECT / 02Representative interface

22%fewer unsupported responses

Enterprise knowledge systems

Useful answers from a million documents.

Created a retrieval and model-routing platform that turns large clinical and enterprise knowledge sets into grounded AI responses.

The challenge

Finding the right evidence across a large document collection called for more than basic vector search.

What I built

Built ingestion, hybrid retrieval, metadata filtering, reranking, and evaluation. Routed tasks across foundation models by capability, latency, and cost.

  • RAG
  • Vector search
  • OpenAI
  • Claude
  • Gemini
  • Bedrock
Representative conversational real estate platform interface

PROJECT / 03Representative interface

32%faster conversational response

Property technology

A better way to search, speak, and discover.

Shipped conversational property search, listing generation, and voice features for a customer-facing SaaS product.

The challenge

The product needed to respond naturally across text and speech while keeping each interaction relevant to the customer.

What I built

Built RAG and real-time voice pipelines with FastAPI, React, and Next.js, supported by personalization and memory services.

  • Python
  • FastAPI
  • React
  • Next.js
  • AWS
Representative healthcare analytics dashboard

PROJECT / 04Representative interface

30%faster database queries

Healthcare software

The dependable software beneath the workflow.

Built healthcare applications, analytics, backend APIs, and secure access patterns for clinical and operational teams.

The challenge

Everyday workflows needed reliable data access, fast queries, and clear permissions.

What I built

Delivered React and Node.js applications, service integrations, role-based authorization, and database tuning.

  • React
  • Node.js
  • Python
  • PostgreSQL
  • AWS

Real challenges. Measurable outcomes.

04 / ABOUT

The engineer behind the work.

I’m Brent, a Chicago-based engineer focused on making complex AI useful in demanding environments.

I bring 7+ years of software engineering experience, including healthcare applications, AI-powered SaaS, and enterprise AI platforms. I studied computer science at Trinity University.

My work is strongest where architecture meets product reality: understanding the workflow, choosing the right technical approach, and measuring how the system performs after launch.
