About

Built by an engineer who's been
shipping software that matters.

Yellow Melon Inc. is a Delaware-based software studio founded by James Drummond — a senior full-stack developer combining a decade of production experience with agentic AI workflows.

The founder

Over a decade of software that had to work.

James Drummond has spent his career working in environments where software failure isn't an option. He was a senior front-end developer on allsaints.com — a million-visitor fashion e-commerce platform with sales days regularly exceeding £1M. He delivered deal-management and accounting software for Universal Music Group with the team at Ingrooves (now Virgin Music Group). He was security cleared to work on software for the London financial services sector.

In parallel, he built Smoothbook.co — an online appointments platform serving hundreds of businesses worldwide, processing 120,000+ bookings and $100,000+ in transactions every month. Smoothbook was acquired by a US company in 2024.

Yellow Melon is the continuation of that work. The positioning is simple: senior engineering judgment, combined with agentic AI workflows. AI tools have made it possible for a single experienced developer to deliver what used to require a full team — but only if the person driving them has the experience to know what to build, how to structure it, and where the real risks are.

James is currently completing a Certificate in Agentic Engineering from the Johns Hopkins Whiting School of Engineering, staying on the absolute edge of what's possible with AI in production software.

How we work

The Yellow Melon principles.

01

Judgment first, code second.

Before any code is written, we decide what the right thing to build actually is. Experience means we catch the hard problems in design, not halfway through the budget.

02

AI accelerates execution, not decisions.

Agentic tools write, test and iterate at a pace a full team couldn't match two years ago. But what to build, how to structure it, where to push back — those calls still belong to the senior engineer driving.

03

Built for North American business.

US English, USD pricing, US and Canadian business-hours coverage. Yellow Melon Inc. is a Delaware corporation serving clients primarily across North America, with secondary work in the UK and Europe.

04

Honest pricing, honest timelines.

Fixed-scope or time-and-materials, depending on what makes sense for your project. No surprise invoices, no scope creep disguised as progress.

Let's talk about your project.

Every good engagement starts with a conversation. No obligation, no pressure — just a chance to figure out whether we're a good fit.
