About
Personal service for the systems that help a business get paid and grow.
Who I am
I'm Zach Senft — a software engineer who has built payment systems and automations at fintech companies including Visa and Flex. That work has to be fast, secure, and correct because real money moves through it every day. It is the standard I bring to payment diagnostics, digital commerce, and every website I build.
I earned a Master's in Computer Science studying at Case Western Reserve University and Johns Hopkins University — done while competing as a student-athlete. If you want a crash course in deadlines, discipline, and performing under pressure, that's a good one.
Senft Web Studio focuses on the payment systems that determine whether recurring revenue is actually collected: failure signals, retry logic, customer payment-update journeys, and the operating decisions around them. Revenue recovery diagnostics are the leading offer. Websites, checkout, and automation are supporting work only when they improve that revenue path or the customer journey around it.
Senft Web Studio is a brand operated by ZSV LLC, a Georgia limited liability company.
Where the work fits
For direct-web subscription businesses, I start with the payment evidence: what first failed, what happened later, and which customer or configuration decision is worth validating. The current proof environment is Stripe test mode; a real engagement begins read-only and does not promise a recovery rate or make automated billing changes.
For local and growing businesses, the work can be a website, checkout, automation, or visibility problem instead. The common thread is simple: understand the actual friction, then build the smallest system that makes the next customer action easier.
How I work
You work directly with me — not an account manager, not an overseas team, not a project coordinator passing messages between departments. I scope it, build it, and answer for it. If something is wrong, you call me.
- Start with the evidence and the decision—not a generic package or an inflated promise.
- Clear scope before access, implementation, or a commitment to a project.
- Direct communication—you get my number, not a ticket system.
- For payment work, sensitive data handling is defined before anything is shared.
The philosophy
義理 — Giri
Japanese: duty, obligation, honor
In Japanese culture, giri is the felt responsibility to do right by someone you've taken on — a social contract that runs deeper than anything you sign. It's why a craftsman loses sleep over a joint that isn't quite right, even when no one else would notice.
That's the standard I bring when a team lets me into a business-critical payment or customer journey. A failed-payment path, a customer update flow, or a checkout decision is not a checkbox in a project plan. It affects a real customer and the revenue they were trying to give you.
When you hire Senft Web Studio, I take responsibility for being precise about what the evidence says, what it does not say, and what should happen next. I take on limited work because that standard requires attention. If I can't give an assessment or project the care it deserves, I won't take it.
Evidence before claims
A dashboard, a metric, or a recommendation is only useful if its evidence and limits are clear.
Simple over clever
The best solution is the smallest one that reliably improves the next decision or customer action.
Honest over comfortable
If your budget, timeline, or expectations don't align with what it takes to do this right, I'll tell you.
Start with the business problem.
Thirty minutes is enough to decide whether an assessment, a project, or a different next step makes sense.
