Alexander builds practical AI systems for automation, agent orchestration, document intelligence, and full\-stack implementation, with an emphasis on systems that can be validated, secured, and deployed in real business workflows\. At Relevate Health, Alexander architected multi\-agent systems for software\-development automation, led agent handoff and orchestration design, and established validation\-first practices through behavioral checks, adversarial testing, quality gates, guardrails, and human\-in\-the\-loop controls\. Alexander also authored a company\-wide adoption proposal that leadership approved and contributed to an internal platform used across the company to ship applications\. Previously, at Outamation through Extern, Alexander developed modular OCR and RAG pipelines for mortgage\-document blobs exceeding 200 pages, including LlamaIndex\-based retrieval, model evaluation, and a demonstration UI\. Beyond internships, Alexander has built Dry Dock, a local AI automation platform with screen reading and agent\-based UI interaction, as well as an AI brain system\. Alexander focuses on shipping AI projects rather than pure research and continually tests new agent patterns and development workflows, including Claude Code and Codex\. ## Highlights - Architected and built AI multi\-agent systems at Relevate Health to automate the software development lifecycle end to end\. - Authored a company\-wide AI\-agent adoption proposal at Relevate Health that leadership approved\. - Led agent\-orchestration development at Relevate Health, defining how specialized agents coordinate and hand off work to deliver complete features\. - Engineered versioned, reusable AI\-agent tooling intended to integrate into any team’s codebase across the organization\. - Designed and ran AI\-agent validation and test harnesses, including automated behavioral checks, adversarial and edge\-case testing, and quality gates\. - Established a validation\-first standard for AI\-agent systems before release at Relevate Health\. - Established autonomous\-agent security and safety standards, including guardrails and human\-in\-the\-loop controls for production systems and data\. - Contributed to Relevate Health’s internal platform used across the company to ship applications\. - Built modular AI\-powered document\-intelligence pipelines for mortgage\-document blobs exceeding 200 pages at Outamation through Extern\. - Combined Tesseract, PaddleOCR, PyMuPDF, and RAG techniques for intelligent mortgage\-document extraction, classification, and search\. - Developed a LlamaIndex and RAG\-based document\-retrieval system optimized for multi\-document mortgage blobs\. - Improved retrieval precision through chunk tuning, metadata filtering, and evaluation of open\-source models including Mistral and Phi\-2\. - Conducted end\-to\-end benchmarking of OCR accuracy, RAG retrieval quality, and routing performance on mortgage blobs of more than 200 pages\. - Delivered a technical report on model trade\-offs, optimization strategies, and deployment recommendations for the Outamation document\-intelligence system\. - Built a demonstration UI for the Outamation document\-intelligence system\. - Built Dry Dock, a local AI automation platform with screen reading and agent\-based UI interaction\. - Built an AI brain system\. - Brings hands\-on experience with OCR, UI automation, plugin development, local models, AI agents, and AI/ML implementation\. - Uses TypeScript, React, Python, Supabase, and PostgreSQL for full\-stack development\. - Pursues a Bachelor’s degree in AI Applications at the University of Tennessee, Knoxville, after completing computer science core coursework at the University of Central Florida\. - Focuses on AI automation, implementation, agent orchestration, RAG, retrieval, evaluation, workflow design, and shipping practical AI projects\. ## Experience - **AI Development Intern at Relevate Health** (2026\-06\-01–2026\-07\-01) — Architected and built AI multi\-agent systems that automate software development end\-to\-end • authored the company\-wide adoption proposal approved by leadership\. • Led agent\-orchestration development, designing how specialized agents coordinate and hand off work to deliver complete features\. • Engineered the system for organization\-wide reuse as versioned tooling built to drop into any team's codebase\. • Designed and ran validation and test harnesses for AI agent systems — automated behavioral checks, adversarial and edge\-case testing, and quality gates — establishing a validation\-first standard before release\. • Established security and safety standards for autonomous agents, including guardrails and human\-in\-the\-loop controls protecting production systems and data\. • Contributed to the internal platform used across the company to ship applications\. - **AI Engineering Extern, Outamation at Extern** (2025\-10\-01–2026\-03\-01) — Built modular, AI\-powered pipelines to process 200\+ page mortgage blob files—combining OCR \(Tesseract, PaddleOCR\), PDF parsing \(PyMuPDF\), and RAG techniques for intelligent data extraction, classification, and search\.
