01 / About

Eleven years of backend. Now building agents.

I'm a senior engineer with 11+ years building production backend systems in financial services — trading, money movement, and securities management — including four years delivering event-driven microservices and high-traffic investment platforms for Fidelity.

Now I design and ship GenAI and agentic AI features end to end: tool-calling agents, multi-step orchestration, and RAG with hybrid retrieval. I also lead internal AI enablement — agentic frameworks, the OpenAI SDK, and organization-scale GitHub Copilot adoption.

02 / Selected Work

Recent work in AI and systems.

01RAG Platform

Code-Analyzer

2025

A code-intelligence platform that ingests and queries large multi-repository codebases — 600+ repos at its first engagement — to power software-engineering audits. A seven-layer hybrid pipeline pairs tree-sitter parsing with a Qdrant + Neo4j + OpenSearch retrieval backbone and cross-encoder reranking.

02AI System

Resume Screener

2025

An AI resume-evaluation system on FastAPI that flags exact duplicates, near-duplicates, and semantic plagiarism through a multi-signal pipeline of hashing, lexical overlap, and embeddings — with PII-aware ingestion and human-reviewable evidence reports.

03AI Platform

Meeting AI

2024

A meeting-intelligence platform that transcribes audio and generates structured minutes, summaries, and conversational Q&A using RAG over timestamped transcript segments, backed by PostgreSQL-native vector search.

04CLI Tool

pull-vids

2026

A universal video and audio downloader CLI built in Go — 1000+ sites, 360p to 4K, playlists and channels, progress bars, and cookie-auth bypass. Installable in one line via a Homebrew tap.

05VS Code Extension

flaunt-github

2026

A VS Code extension that turns every file save into a digital milestone — capturing your coding journey as a living, GitHub-style contribution chart.

06Python Package

always-decimal

2025

An open-source Python package on PyPI for safe conversion of floats, strings, and numbers into Decimal objects — resolving the numeric-comparison pitfalls between PostgreSQL values and Python floats.

PythonPyPI
07Web App

everyday-developer-tools

2024

A web app bundling 16+ everyday developer tools — JSON validators and schema generators, regex helpers, string and time utilities, encoding and fake-data tools, and Markdown ⇄ PDF conversion. A FastAPI backend exposes each tool as a typed JSON endpoint; a Vite + React frontend ships alongside it in a single Docker image.

08Dev Tooling

copilot-anatomy

2026

A reference implementation for configuring GitHub Copilot across a multi-model, polyglot team — every customisation primitive (instructions, prompts, skills, agents, chat modes) plus governance tooling. One script scaffolds the full .github/ structure into any repo, and an interactive browser visualisation maps how the pieces fit together.

09Learning Guide

copilot-howto

2026

A structured, visual, example-driven guide to mastering GitHub Copilot — 16 tutorial modules spanning every feature, from slash commands and custom instructions to skills, agents, MCP, and governance. Each module pairs Mermaid diagrams that explain how a feature works under the hood with copy-paste templates and a progressive beginner-to-advanced path.

03 / Experience

Where I've spent my time.

Designing agentic systems that automate enterprise infrastructure and onboarding.

  • Built the TerraCore Onboarding Agent — an agentic system using LLM tool-calling and multi-step orchestration to automate environment provisioning and account servicing.
  • Exposed the agent as an async FastAPI service with streaming progress, coordinating Terraform, Jenkins, and account-servicing APIs as agent tools.
  • Engineered guardrails — input validation, allow-listed actions, dry-run modes, and human-in-the-loop gates — for safe, auditable runs in regulated environments.
