Senior product engineering, paid weekly

We turn prototypes into minimum lovable products.

You have all of the features that you want, but you've been running in circles, fixing bugs only for new ones to surface. Presenting this to users would mean you get to learn nothing about the viability of your business. We can help you.

We bring in a senior software developer who can own your codebase end to end
You see progress in production every week.
We improve your AI harness with tests, monitoring, agentic reviews and static analysis while we're shipping.

$2,000 / week. We scope work together through GitHub or Linear issues and handle one request at a time.

01 / Selected work

We've been around the block.

We're a team of tech professionals who have been in and around startups for over a decade each. We've launched products that had to handle thousands of events per second or hundreds of thousands of dollars in first-week volume.

Real-time trading platform

The prototype ran out of memory every hour.

It ingested Binance futures data and computed trading signals based on a proprietary formula. We separated ingestion, processing, signal computation, execution, and a backend for frontend into services, and used low-latency queues to manage the workload.

The shipped system handled thousands of market-data points per second across hundreds of assets.

Custom iGaming platform

The beta exposed flaky, inconsistent, and often slow third-party APIs.

We improved observability then built an idempotent system with checks, stuck transaction cancellation, retries with fee bumps, safe state rollbacks, and visible error states for game rounds that could not settle.

Launch was uneventful. The first week did $300k in volume.

A monitoring & analytics platform

With tens of millions of data points, some dashboards took minutes to load.

To make it to launch in time, we implemented heavy caching with long TTLs. To fix the root cause, we created background jobs to precompute daily data aggregates.

Page load time fell to one second, with staleness at no more than a few minutes.

02 / FAQ

FAQ

Can I cancel?

You can cancel before the next weekly renewal.

What if the first week isn't right for me?

If the first week isn't right for you, request a full refund during that week.

Does my code go to AI providers?

Yes. The agents run on Anthropic and OpenAI models, so they read the code they work on. Credentials and secrets never go to them.

03 / Next step

Ready when you are.

Send Alex the product or repository link and a short note about the work. We will confirm fit and availability, then we can get going. We can typically start an engagement within 48 hours if the fit is right. If it turns out we are not working out, you can get a full refund during the first week.
