Finance for U.S. companies+the software to run it

The accountant who also ships the software.

Accounting and business administration graduate, with a Big Four audit and consulting background. For 5+ years I've worked only with U.S. companies: bookkeeping, month-end close, FP&A. Now I also build the internal tools those teams run on.

Three ways I take work off your plate.

(Services · 03)
01

Internal tools

Custom software for finance workflows, designed by someone who has actually run them. From idea to a tool your team uses daily, in weeks, not quarters.

Web appsAutomationsAI assistants
02

Bookkeeping & close

Full-cycle bookkeeping, reconciliations, and month-end and year-end close that stands up to review. For small businesses on QuickBooks, that's Luca.

FP&A & reporting

Budgets, forecasts and variance analysis that turn clean books into decisions leadership can act on.

Bookkeeping for U.S. businesses on QuickBooks Online. One accountant closes your books by the 5th and explains them in plain English, and you watch it happen in a live portal. From $500 a month, month to month.

Mío

Live shopping for sellers in Argentina. Sellers go live in the app or share one link on TikTok and Instagram; buyers tap "mío", the payment lands straight in the seller's Mercado Pago, and orders come out sorted, shipping labels included. On the App Store, with its first real sale in October 2026.

Huellitas

Snap the paper vaccine booklet and every shot is logged with the next dose and a reminder. A camera coach sees your dog and talks you through training, walks log themselves on a live map, and lost mode gets everyone looking.

(Why an accountant who codes)
Adriel Kornschuh.

Most internal tools fail because the builder never sat through a month-end close. I have, hundreds of times, in Big Four audit, global consulting and U.S. accounting practices. So what I build matches how finance teams really work.

Buenos Aires, U.S. business hours
(Working with me from outside the U.S.)

The questions every U.S. buyer asks. Answered up front.

01Hours & response time

I work U.S. business hours from Buenos Aires, just one or two hours ahead of Eastern time. Same-day replies are the norm, not a courtesy.

02Contracts & invoicing

I invoice as a foreign independent contractor under a W-8BEN. No U.S. payroll, no entity setup, no withholding complexity on your side. You just pay an invoice.

03NDA & data handling

Happy to sign your NDA before seeing anything. Your data stays in accounts you own and control. I work inside your systems, never on copies of them.

04What if I disappear?

Everything I build ships with source code in your repo, documentation, and admin access in your hands. Your team keeps the keys from day one.

(Contact)

Tell me what's eating your team's hours.

The messy close, the spreadsheet everyone fights over, the report nobody wants to build. I reply within 24 hours with how I'd approach it. No call, no calendar link, just a straight written answer.

Opens pre-written in your email. Hit send there, and I reply within 24 hours.
