About this Gig
Is your app secure? I help you find and fix the security weaknesses before attackers do.
I am an iOS developer specialised in app security. I work with Swift and SwiftUI and secure mobile apps and their backends so your users' data stays safe and your app is ready for the App Store.
What I offer:
- Security Guide: a clear written cybersecurity guide for your app, with a risk overview, best practices and a ready-to-use checklist you can follow yourself.
- - Vulnerability Patching: I review your app/backend and fix the security issues for you, then deliver a hardened, tested build.
- - Pentest + Patch: I actively test your app for weaknesses (with your authorization), patch every issue found and hand back a secured build plus a short report.
Typical issues I fix: insecure data storage, weak network/TLS, broken authentication, exposed APIs, hard-coded secrets, vulnerable libraries and unsafe release configs.
Important: I only test and modify apps that you own or that you give me written permission to work on. Unauthorized testing of third-party systems is not offered.
Not sure which package fits? Message me about your app and I'll point you to the right level. German-speaking, Swiss.

FAQ
What do you need from me to start?
Written confirmation that you own the app or are authorised to have it tested, access to the code or app (file, zip or repository link), and a short description of what worries you. Without that authorisation I cannot start.
Do you speak German?
Yes. I am based in Switzerland and work in German, English, French and Italian. You can brief me in German and get the security report in German or English, whichever you prefer. Same CET timezone if you are in Europe.
Will testing break my live app?
No. I work on a copy or a test build and never touch production without your explicit go-ahead. Every change is documented and delivered so you can review it before you deploy anything.
What is the difference between the three packages?
Security Guide is a written analysis and checklist you act on yourself. Vulnerability Patching means I fix the issues in your code. Pentest and Patch adds a full penetration test with your authorisation, then fixes everything found.
Do I get a report I can show a client?
Yes. You get a written report listing every finding, its risk level, and what was done about it. It is written so a non-technical stakeholder can follow it, which helps for App Store reviews, client audits and data protection questions.
