We build the data work, dashboards and software companies keep postponing, in Python, on your domain, with the code handed over. The same work is what entrepreneurs resell under their own name, and what people breaking into tech learn on.
The numbers already exist, in exports, in the CRM, in a spreadsheet someone maintains by hand. What’s missing is someone to connect them, and the last two years have made that harder, not easier: every tool now needs a specialist before it returns anything.
We skip that part. You describe the decision you’re trying to make. We build the thing that answers it, and we explain how it works so your team can keep it running.
Two weeks, fixed fee. We map the sources you point us at, set out exactly what conflicts with what, and hand you a costed plan.
We specialize in Google Sheets and Apps Script. Your numbers land in Sheets and refresh on a schedule, so nobody installs anything and nobody buys a seat.
That work is a script. It should run at 6am on the first of the month without anyone opening a laptop.
Sessions on your own data, not a toy dataset. What these tools do well, where they quietly get it wrong, and how to check an answer.
Django, FastAPI or a static site, depending on what it has to do.
If your client runs Google Workspace this can be a branded Sheet driven by Apps Script rather than a whole application, which launches faster and costs you less to run.
Your brand and palette from the first commit. We do not appear in it.
Built once, configured for you, run under your brand for as many clients as you sign.
Send the scope you sold. We will tell you what it takes and what it costs you.
Machine learning, data analysis or web development, on an actual messy dataset with milestones and code review.
We sit with you while you work it. We help you read the brief, choose an approach, unblock you, review your code and rehearse the follow-up questions.
Python aimed at doing something real in week one rather than finishing a syllabus.
A README that explains your decisions and a CV that describes the work in the language of the job ad.
The same engineering underneath. What changes is who owns the result at the end.
You have data and no one to work it. We build the pipeline, the dashboard and the internal tools, then hand them over documented.
You have clients and a sales pitch. We build what you sell them, under your name, not ours.
You need something real to show, and a straight answer when you’re stuck. Both are here.
Python end to end, so one team covers the pipeline, the model and the interface.
Start with the questions at the top of this page. That is the intake, and it takes about a minute. If you would rather talk it through, ask and we will call you. Either way you get one page back: what gets built, what it costs, and our estimate of when it lands.
We aim to have a working link in front of you in the first week rather than a slide deck. Rough, but real, and you steer from there.
Deployed to hosting you own, with the repository transferred to your account and a README that a new hire could follow. We will set the hosting up with you, but the account is yours from the first day.
Included in the scope we agree. Bugs, small changes, and a session to get whoever inherits it comfortable. A retainer after that is optional.
One email, one call, one page back. If it isn’t a fit we’ll say so and point you somewhere better.
