Über diesen Service
You inherited a web app, or you're paying a developer and can't tell if the work is good.
Before you spend more, find out what you actually have.
WHAT YOU GET
- Architecture and code quality review, front end and back end
- Tech debt and scaling risks, ranked by impact
- What it will cost to grow on this codebase, or to rebuild
- A plain-language report with a ranked fix plan
- A call to walk you through it
WHO IT'S FOR
- Founders who took over code from an agency or freelancer
- Teams before a funding round, a sale or a big new feature
- Owners of AI-built apps that need a senior check
WHY ME
- Fractional CTO and lead software engineer for a private aviation company, 2022-2026
- 15 years of engineering judgment, 250+ clients since 2014
- I build with AI agents every day and review code line by line
Web app security has its own audit. This one is about quality, structure and cost.
Send me your stack and what worries you most. I'll tell you where I'd look first.

FAQ
Can you work with my existing developers or agency?
Yes. Much of the value is reviewing what they build, setting standards and keeping the work on track.
Do you sign an NDA?
Yes. Your code and business details stay private.
Which stacks do you work with?
JavaScript and TypeScript web apps: Node.js, Angular, Firebase and similar, plus Shopify.
Which time zone do you work in?
I overlap with US business hours until about 4:30 pm ET, and I reply fast.
What happens after the package ends?
We continue monthly, or I hand everything over with clear documentation.
Do you need access to my code?
Read-only access to the repository is enough. I don't change anything during the audit.
How is this different from the web app security audit?
This one covers quality, structure, scaling and cost. The web app security audit covers vulnerabilities, access, data exposure and payments. Many clients do both.
