AI, LLMs, and Intelligent Systems
Founder @ UpwardBit Ventures | Architecting AI systems with RAG, intelligent automation, and multi-agent orchestration

About Me

I build production-grade AI systems that combine LLMs, retrieval, and graph reasoning with solid engineering fundamentals. With 30+ years across startups and Fortune 500s, I balance architecture decisions with hands-on delivery.

Today I run UpwardBit Ventures, a boutique consultancy focused on AI/GenAI systems and intelligent automation. Recent work includes RAG pipelines, knowledge-graph-backed search, and multi-agent orchestration using OpenAI, Claude, LangChain/LangChain4j, pgvector, and modern DevOps.

My background spans health tech/wearables, government (GEOINT), and enterprise platforms. I lead teams end-to-end—strategy, architecture, and execution—with a bias for reliable, observable systems that ship.

Across developer/architect, manager, and TPM roles over the last 3+ years, most of my delivery has centered on AI/LLM products and platforms.

Projects

Memspan.ai - Portable AI Memory Archive

2025
https://memspan.ai

Memspan.ai is a file-based memory archive that keeps your identity, saved memories, and project conversations portable across LLM tools. It extracts and organizes exports from platforms like ChatGPT, then lets you selectively load that context into Claude Code or other assistants without relying on vendor-locked memory.

Key capabilities include identity extraction prompts, ChatGPT memory export tooling, project conversation correlation, and the cc-memspan launcher that assembles the right context for each session. The system is deliberately database-free, emphasizes user-controlled loading, and offers Makefile helpers for quick setup and repeatable workflows.

Tech Stack: Python, Bash, Git, OpenAI, Claude

National Security Hackathon - Knowledge Graph + LLMs

2024
https://devpost.com/software/digital-desperados

The National Security Hackathon for Defense in San Francisco brought together over 500 participants across 64 teams, all tasked with addressing complex challenges in next-generation intelligence analysis, drones, computer vision, and AI, including GPT and LLMs. We focused on a significant problem: processing and extracting actionable intelligence from the overwhelming amount of unstructured data generated daily—approximately 300 million terabytes. Our solution aimed to transform this information overload into strategic insights by developing a sophisticated data pipeline.

Leveraging Large Language Models (LLMs) and a graph database, we built a system that extracted key entities from diverse data sources, such as unclassified military briefs, social media feeds, and global news outlets. These entities were used to construct a deep knowledge graph that provided insights into the relationships between people, places, events, and outcomes. Additionally, our solution featured capabilities for chat-based Q&A on the knowledge graph and summarization of intelligence over time.

Art Analyzer - GPT Vision and LLM

2023
https://eric-blue.com/2023/12/05/art-analyzer/

I wanted to see how quickly and effectively GPT-4V (gpt-4-1106-vision-preview) could analyze artwork given an uploaded image. I primarily wanted to do this for experimenting with my own artwork, but also interested in discovering what type of critique and feedback it would give on famous artist’s work.

This project was written in Python, uses Steamlit and integrates with OpenAI. I’d also done some early evals of LLaVa on HuggingFace.

ActiveOS - Mindstream

2016
https://activeos.com/case-studies-sgu-mindstream/

In mid-2016, Ian V.J. Murray, PhD, Associate Professor of Physiology and Neuroscience at St. George University approached ActiveOS with a funded research project that needed to steam, capture and analyze brainwave data utilizing a Neurosky EEG sensor.

No software on the market currently offered real-time streaming of concurrent EEG headsets via Bluetooth and no easy way to save this data to the cloud for performing historical storage and analysis of attention and various brainwave states.

In parallel with building the client technology, named MindStream, ActiveOS created an extension to the Enterprise Platform product for streaming and saving real-time EEG (thousands of records per second) and other biometric data.

  • Added ability to simultaneously stream up to 6-8 EEG headsets using a custom bluetooth integration

  • Integrated EEG data streaming using a combo local interface (windows, mac) and cloud-based streaming (ActiveoS+Vert.x)

Tech Stack: Java, Spring, Node, Bootstrap, JQuery
