Drop in one or more X12 835 remittance files and get a clean three-sheet Excel workbook back. Payment summary, claims, and service lines, with CAS adjustments flattened. No upload, no install, no BAA.
The IT Orchestrator

Browser-only tools built for healthcare operations teams. Every file is processed locally. Nothing is uploaded.
Drop in one or more X12 835 remittance files and get a clean three-sheet Excel workbook back. Payment summary, claims, and service lines, with CAS adjustments flattened. No upload, no install, no BAA.
Healthcare CSV pre-validator. Catches Excel corruption, format errors, and schema violations in eligibility, member roster, and billing exports before they reach your downstream system. Runs entirely in the browser.
Every Stefo Tech product runs entirely in your browser. That is a deliberate design choice, not a limitation.
Your file is parsed inside the browser tab. It is never uploaded to a Stefo Tech server because there is no Stefo Tech server in the data path.
Stefo Tech is not a Business Associate for these tools, because no PHI ever reaches Stefo Tech. That removes a procurement step and a category of risk.
Open a URL. Drop a file. Get a result. Nothing to install, nothing for IT to approve, nothing to update.
Deterministic processing, not LLM inference. No tokens, no rate limits, no surprise bills. The hundred-thousandth conversion costs the same as the first.
Stefo Tech is a one-person practice. The work is hands-on, hourly, and built on twenty years of running real environments. Engagements span industries; the technical core is the same regardless of vertical.
Tenant administration, identity, email, collaboration, voice, security baselines, and migrations across the major business cloud suites.
Windows, Mac, and mobile device deployment, app packaging, compliance, and conditional access through modern MDM platforms.
Firewalls, switching, VLAN segmentation, wireless coverage, site-to-site links, and clean documentation when it is over.
Single-file web tools that replace a spreadsheet ritual or a manual workflow. No servers to maintain, no licenses to renew.
Industries served
Healthcare revenue cycle, behavioral health, non-profit and faith-based organizations, professional services, and small-to-mid business operations. HIPAA-aware engagements when the work calls for it.
