Cartoon drawing of my face

Overview

I design and build production AI systems end-to-end: LangGraph orchestration pipelines , RAG architectures with fuzzy entity resolution, WebLLM on-device inference over WebGPU/WASM, and structured state extraction using JSON-mode reasoning models grounded in persistent vector stores.

My AI work is backed by 9 years of cloud engineering on AWS : serverless architectures, cross-region active-active infrastructure, GraphQL and REST APIs, and NoSQL databases at billions-of-records scale . I build AI systems that are integrated into real cloud infrastructure, not isolated experiments.

As a Solutions Architect I have a consistent track record of taking stakeholder ideas from concept to shipped product without hand-holding: translating ambiguous requirements into concrete system designs, owning the architecture decisions, and delivering across the full stack independently.

Money Studio

Money Studio Logo

Founder & Principal Engineer

Software Startup

Built as founder and principal engineer : a TypeScript monorepo shipping a financial visualization platform to 5 platforms (web PWA, iOS, Android, Electron, Tauri) from a single codebase

On-device AI assistant powered by WebLLM (WebGPU/WASM) with a custom RAG pipeline grounded in the user's financial data via an encrypted local vector store

Architected a knowledge graph data layer, a node-based visual logic editor , and an AWS CDK backend with full IaC security scanning ( SAST , SCA , DAST , Checkov, OpenSSF Scorecard)

Integrated 5 Web3 wallet connectors (MetaMask, Coinbase, Phantom, Binance, Gnosis Safe) to include live crypto holdings in the financial knowledge graph

Interactive Narrative World Engine

Local LLM Simulation System

Personal Project

Designed an 8-node LangGraph pipeline for AI-assisted fiction: pre-response schedule reconciliation and spatial analysis ground every model response in consistent world state before generation

Fuzzy entity resolution via persistent Chroma vector stores prevents hallucinated inventory mutations; a secondary reasoning model (JSON-only, lower temperature) writes all state deltas deterministically to SQLite

Scene-aware image generation pipeline reads SQLite world state to compose diffusion prompts, select LoRAs , and choose sampler parameters entirely from structured data

QuantPy

Python Portfolio Optimization Library

Personal Project

Python library implementing Modern Portfolio Theory : Sharpe ratio maximization, minimum variance optimization, and efficient frontier tracing via SciPy SLSQP constrained optimization

Implemented the closed-form Two-Fund Separation Theorem for exact analytical weight solutions alongside the numerical optimizer, enabling comparison of both approaches on the same frontier

Rendered interactive Plotly efficient frontier charts from a universe of 40+ tickers, overlaying cumulative return traces for equal-weight, Sharpe-optimal, and benchmark portfolios (SPY, QQQ)
