A technical lead who builds.

I lead AI and automation development at GreenTomatoMedia. Alongside that role, I work with clients on websites, business systems, and the connections between them.

Current role / GreenTomatoMedia

Lead Developer:
AI & Automation

I joined GreenTomatoMedia as a fullstack developer in 2024. Today my focus is AI and automation, building on experience in architecture, feature delivery, code review, and the systems behind media operations.

Read the role overview

The background

From operations
to the systems behind them.

My first professional role was in customer service at a logistics company in 2021. Website administration and operations work followed. I completed a Computer Science degree and a fullstack bootcamp in 2022, then worked on web and mobile applications at Organic Social Software in 2023.

That mix of operations and engineering carries into my client work. I built a gym operations platform across 5+ branches, and a website for Sound Healing Chiang Mai in three languages. Different projects, each shaped around a concrete need.

I also publish tools I want to use myself: Django packages for rate limiting and safer migrations, and Torpor, a native macOS tool for managing Claude Code sessions.

How I work

The decisions matter as much as the code.

Understand the real workflow.

Start with the people doing the work: what they use, what they repeat, and where information gets lost. That context shapes the software.

Stay close to the build.

Connect the decisions to the implementation. Architecture, interfaces, integrations, and delivery are parts of the same job.

Leave a system people can use.

Make the important paths clear, write down decisions, and document what the next person needs to know.

For the technically curious

The experiment below explains one rate-limiting rule using sample traffic. It is a browser demonstration, not a live service or the Python package running in your browser.

The workbench / Try a rule

What happens
when traffic spikes?

A small, playable explanation of rate limiting. Set an allowance, send requests, and watch the boundary do its job.

Explore django-smart-ratelimit
Sample data · fixed-window modelt = 0s

Allowed total

Ready. Send a request or a burst to see the rule in action.

Browser simulation; no network requests. Time advances only when you press the button. Changing the allowance starts a new experiment. The package supports additional strategies and storage backends.

Put that experience to work.
