WALTHER TECH SOFTWARE — BÜRSTADT, GERMANY

Apps for Apple platforms and Android.
And the secure infrastructure behind them.

Independent engineering practice of Vladimir Valter: native app development for iOS, macOS and Android, hands-on Linux server operations, and offensive security testing — one engineer, full accountability.

What I do

Three disciplines, one engineer

App development

Native apps for iPhone, iPad and Mac in Swift and SwiftUI, and for Android in Kotlin — from first prototype to App Store and Play Store release, including ongoing maintenance.

DevOps & infrastructure

The servers that keep those apps running: Linux administration, Docker deployments, CI/CD pipelines, nginx, TLS, backups and monitoring — boring, reliable operations.

Offensive security

Penetration testing and red team engagements against your apps, APIs and infrastructure — strictly scoped, contract-authorized, with actionable findings and remediation guidance.
