Proof that the work holds up.

Caliper QA tests the systems that cost real money when they break: quote-to-cash, payments, the APIs underneath them, and the AI features now making decisions inside both. One senior engineer with nineteen years in enterprise systems. The person on the call is the person who does the work.

What I test

Engagements run as fixed-scope projects, monthly retainers or blocks of hours. Rates are published below each service.

Salesforce CPQ and quote-to-cash audits

From $4,800 or $120 an hour

Pricing rules that fire in the wrong order, quotes that do not match the invoice, renewals and amendments that quietly drop a line item or a discount. I test the full path from configuration to cash, including Logik.io, and hand you the failing cases in writing.

  1. MapBundles, price rules, approvals and the contracts they produce, ranked by what a wrong answer costs.
  2. BreakNew quotes, amendments and renewals run against every rule that changed, edge cases first.
  3. Hand overA written report with reproducible cases and a regression suite your team can rerun each release.

AI feature evaluation

For teams shipping AI into processes that get examined later. I build the evaluation set, run it against your feature, document failure modes with reproducible cases, and leave a record of how each output was checked.

From $5,400 or $110 an hour

API and performance testing

Four years of this on a banking platform. REST and GraphQL endpoints validated under load, latency measured before a release instead of after an incident, and the breaking point found on purpose.

From $3,900 or $85 an hour

Quality engineering and automation

Test strategy, automation frameworks that survive a release schedule, integration coverage, and a plan for the flaky suite nobody trusts anymore.

From $3,900 or $85 an hour

Data, BI and reporting

Reconciliation between source systems and dashboards, validation of the numbers leadership acts on, and checks that keep running after I leave.

From $3,900 or $85 an hour

Release readiness review

A short, fixed-scope look at whether one release is safe to ship: coverage gaps, risk ranking, and the three things worth fixing first.

From $3,900

QA process assessment

For teams whose testing grew by accident. I review how work moves from ticket to production and hand back a written plan your team can run without me.

From $3,900

Who you are hiring

I am Fabián Arce. Nineteen years in enterprise systems, eleven of them in quality engineering. Before that I built ETL pipelines and reporting systems for Procter & Gamble, which is why reconciliation work comes naturally: I have been on both sides of the data, building the pipeline and then breaking it.

Most of my career has been spent on software that moves money. Four years owning quality end to end on a digital banking platform: accounts, authorization, interbank transfers, check processing and the reconciliation between them. Then Salesforce CPQ and Logik.io at Teradyne, from product configuration and pricing rules to approvals, bundles, discounts and everything downstream to invoicing.

Most of what I find lives at the edges. The order with one line item priced at zero. The renewal that crosses a fiscal year. The customer record with an apostrophe in the name. Happy paths get tested by everyone; the cases that reach production are the ones nobody thought to write down.

I work from Heredia, Costa Rica, in US time zones, and contract as an independent professional.
