Areas of Expertise

Current engineering focus at RocketGate.

Payment Platform Engineering

Full-stack engineering on payment infrastructure at RocketGate: merchant integrations, transaction reconstruction tooling, and the internal software behind payment platform operations.

Developer Tooling & Workflow Visibility

Leading Workflow Intelligence, a Laravel/Vue platform giving engineering teams visibility into work items, stage history, and delivery progress.

AI-Assisted Development

Using AI-assisted workflows to move faster from prototype to production, without cutting corners on code quality or maintainability.

I'm drawn to the behind-the-scenes software that makes everyone else's job easier.

Selected Work

The flagship platform I'm building at RocketGate, and the professional systems built around it.

Internal Platform

Workflow Intelligence

Laravel • Vue • TypeScript

The flagship platform I'm building at RocketGate: replacing scattered status updates with a single source of truth for how engineering work actually moves.

Private/internal application. No public demo available.

Verbatim

RocketGate

Grounded documentation Q&A and support assistance.

Retrieves and ranks source chunks deterministically, then uses an LLM only for synthesis — every citation maps back to the exact retrieved section, with graceful escalation when confidence is low.

Transaction Toolkit

RocketGate

Local-first payment investigation and analytics.

Snapshots transaction history locally, then analyzes the same dataset across declines, retries, and concentration — deterministic reporting by default, with optional AI explanation layered on top.

Knowledge Exporter

RocketGate

Deterministic knowledge extraction for portable, diffable content.

A provider-abstracted pipeline that converts Freshdesk and Confluence content into deterministic Markdown, using SHA-256 comparison so reruns diff cleanly instead of rewriting everything.

AI-Assisted Developer Tools

Personal tools exploring how AI fits into a real development workflow.

Well Prompted

Personal Project

Developers lose time re-deriving good prompts for the same recurring tasks (debugging, documentation, code review) from scratch every time. Built a structured prompt library with React, Node, and Prisma that keeps AI-assisted development consistent and reusable across a codebase instead of ad hoc.

PromptWorks

Personal Project

Writing a clear, well-structured AI prompt takes iteration most people don't have time for. Built an AI prompt-generation tool with React and Node that turns a rough goal into a reusable prompt: useful for technical documentation as much as general business writing.

Well Applied

Personal Project

Job applications benefit from tailored, specific language, but writing that from scratch for every posting doesn't scale. Built an AI assistant that generates tailored prompts for applications and interview prep, extending the same structured-prompt approach into a non-developer use case.
