About
The technical co-founder energy, without the equity conversation.
Who I am
Zach Senft · Atlanta, GA
I'm Zach Senft, a software engineer and founder who consults for founders building apps and SaaS. I review what was built, find the security gaps before production does, and help make the right technical decisions before they become expensive ones.
Before starting Senft Web Studio, I built payment systems and automations at fintech companies including Visa and Flex. That work has to be fast, secure, and correct, real money moves through it every day. That rigor is what I bring to every security audit and software engagement.
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.
Beyond client work, I build and ship my own products: Belltower is a Bible reading app live on iOS and Android, and SecondWave is a marketing tool for app builders currently in development.
Senft Web Studio is a brand operated by ZSV LLC, a Georgia limited liability company.
Where the work fits
The most common entry point is a founder who shipped fast, with AI tools, a contractor, or a small team, and now needs a real engineer to look at what was built. Security audits, architecture reviews, and fractional technical advisory are the core offering.
I also build apps and SaaS products from scratch, and take on website and automation projects for local businesses and startups that want a credible digital presence. The common thread across all of it: understand the actual problem, then build the smallest system that solves it correctly.
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 security work, read-only access and data handling are 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 founder lets me into their app. A security gap, a broken auth flow, or a bad architecture decision is not a checkbox in a project plan. It affects real users and the business they're trusting with their data.
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 engagement 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.
