AI Strategy & Architecture

Leveraging my experience as a CTO and startup advisor, I partner with your leadership to de-risk your AI investment. We'll define a clear technical roadmap, architect a system for reliability and scale, and ensure your AI initiative delivers tangible business value.

Custom RAG & Search Systems

Drawing on 15 years of productizing advanced R&D at MIT Lincoln Lab, I build production-grade Retrieval-Augmented Generation systems. I specialize in creating secure, accurate, and maintainable solutions that turn your private data from a liability into a strategic asset.

Agentic Workflows & Fine-Tuning

Go beyond simple chatbots. I design and build stateful AI agents that execute complex, multi-step business processes. With deep experience in the entire language technology stack, I also fine-tune open-source models to create specialized AI personas with unique, high-value skills.

The AI Trilogy: From Architecture to Agency

Three fully functional applications, built from the ground up to demonstrate a clear progression of skill and value. Each project serves as a case study for a core consulting offering, moving from foundational RAG architecture to behavioral fine-tuning and finally to complex, goal-oriented AI agents.

What are your AI Challenges?

How do we de-risk a major AI investment and show a clear path to ROI?

Our engineering team is brilliant, but they lack the deep, specific experience to navigate the modern AI stack.

We need to cut through the hype and architect a solution that is reliable, scalable, and production-ready.

If these are the questions your leadership is asking, you've come to the right place. This is the intersection where I provide value.

A 30-Year Career in
Applied AI & Language Technology

For over 30 years, my focus has been singular: transforming complex language technology from research concepts into market-ready products.

Today, as a Principal AI Architect, I leverage that experience to help senior technology leaders de-risk their AI initiatives—partnering with engineering teams to turn ambitious prototypes into reliable, scalable enterprise systems.

My journey began at the forefront of the commercial speech recognition industry, building core ASR/TTS systems for early speech startups. I joined Premiere Technologies pre-IPO, where my work on their core platform was featured in their successful NASDAQ offering. Later, as CTO and VP of Engineering for Voice Automation, I built and led the engineering team that architected complex voice-enabled enterprise integrations, resulting in our selection by Microsoft as an official launch partner for their Speech Server.

This intensive commercial experience was followed by a 15-year tenure at MIT Lincoln Laboratory. As a senior software engineer, I was responsible for productizing groundbreaking algorithms for mission-critical national security applications, ranging from advanced speech intelligence to Space Domain Awareness systems.

Now, as an independent consultant, I bring this rare combination of startup velocity, executive-level strategy, and research-grade rigor to my clients. I don't just build AI features; I architect the robust systems that become a core part of your business.
