Scattered parts gather into one working system; the amber dots are payments moving through it.

Built for the day it fails halfway.

Your payments, your legacy platform or your slowest job has outgrown what it was built for. We find where it breaks, fix it, and hand it back to your team.

Your payments work on a good day. We make them hold up on a bad one.

A payout that times out after the provider accepted it. A webhook that arrives twice. A worker that dies in the middle of a money job. We find where your system breaks on days like that and close the gaps: idempotency keys, duplicate-event protection, partial-failure recovery, and a reconciliation finance can close the month from.

Every engagement starts with a fixed-fee assessment of the system you have.

Practices

What we work on.

Each starts with a fixed-fee assessment: a written report and a costed roadmap.

A row locks only when ledger and bank agree.

01 / 03 Payments

Payments that reconcile.

Accepting, paying out and reconciling on Stripe, Adyen, Unit, Checkout.com, Plaid, Visa Direct and Mastercard MoneySend. Every integration gets idempotency and a daily check of ledger, provider and bank.

Payments practice
Routes move one at a time while traffic keeps flowing.

02 / 03 Modernization

Move it while it runs.

Off .NET Framework, Java or the monolith without a big-bang rewrite. A strangler façade moves one slice at a time, so you keep shipping throughout.

Modernization practice
Work piles up at one narrow point until it is widened.

03 / 03 Performance

Find what makes it slow.

The slow job, pipeline or hot path your business waits on. We measure it, explain it, then fix it against the number: code, queries, I/O, concurrency or infrastructure.

Performance practice

Method

How an engagement runs.

Every practice follows the same four steps. The assessment has a fixed fee, and you keep its report even if someone else does the build.

Risks found and marked, sorted first, built tier by tier, handed over.
  1. 01 / 04 1 to 3 weeks

    Assess

    A fixed fee, agreed before we start. We read the code, the data and how it runs, and mark every risk by severity. You get a written, severity-ranked report.

  2. 02 / 04 Assessment

    Plan

    A target design and a costed roadmap, ordered so the riskiest things come first. You can stop here and build with anyone.

  3. 03 / 04 Fixed price

    Build

    A date, change control and milestone billing. A design document comes before any code that touches money or data, and you get a written status every week, including when the news is bad.

  4. 04 / 04 Yours

    Hand over

    The system and its design documents move to your team. If you want us on call for what we built, a monthly retainer is priced on coverage and response time.

Self-checks

Check before you call.

Three self-checks built from our own checklists. Scored in your browser, nothing sent.

Record

Proven in regulated production.

Our principal, Rey Narvaez, delivered these results in regulated production before Aripone was formed, over more than a decade as a senior engineer in reinsurance, fintech, identity and money movement.

  • Minutes

    Payments. Push-to-card payouts over Visa Direct and Mastercard MoneySend on a regulated banking platform, reaching the card in minutes instead of days, with idempotency and partial-failure recovery.

  • 27h → 8h

    Performance. A regulated calculation job cut from 27 hours to 8 per run, so it can run three times as often.

  • 30%

    Performance. About 30% of the database load removed from a production platform.

  • C# / .NET

    Modernization. C# and .NET estates moved to modern stacks.

Every fee is published.

Every part settled into one system that keeps running.
