Your hire takes six months. Your roadmap can't wait.

Senior TypeScript engineer on contract. I build and run PartyX alone: six apps, live payments, pipelines and the cloud under them. You get that person from week one, for as long as the gap lasts.

Why me, not the usual options

Three ways to fill the gap. One person who has already done the hard part.

Instead of an agency

The person on the call writes the code

You pay for a team, the work goes to whoever is free
One senior engineer who writes and reviews every line

Instead of a platform freelancer

Owned production, not just features

Most have shipped tickets inside someone else's system
Two years running payments, refunds and on-call for my own product

Instead of waiting for a hire

Starts in weeks, ends cleanly

Months to find, a notice period on top, then onboarding
Contract starts fast and hands over when your permanent hire arrives

Start with two paid days.

One real ticket from your backlog. You see the code, the review notes and the questions I ask. Then decide.

Built for 2026

AI writes the code now. The job is knowing when it is wrong.

Frontend

React, Next.js, Vue, React Native, design systems, realtime UI. The guest app and the industrial console.

Backend

APIs, data models, background jobs, payments, auth. Less time in Java and Go.

Cloud and operations

Cloudflare, Vercel, AWS basics, pipelines, monitoring. Not my lane: Terraform, Kubernetes, very high traffic.

The bottleneck moved

Review, not typing

With agents in the loop, pull requests run about 50% larger and wait around four times longer for a reviewer. I am the reviewer who also ships: agents draft, I own every line that reaches production.

Where agents fail

The unhappy path

They build the checkout that works and miss the refund that should not be allowed. PartyX's payments, payouts and refunds are exactly that code, live for two years with real money on it.

What one person means now

Deciding, not generating

Six apps in 22 months is not typing speed. It is choosing what to build, what to reject and what to delete, then carrying the pager for the result.

Why it matters 45% of AI-generated code ships with a known security flaw (Veracode, 2026). Somebody has to be the other half.

Fixed price
