I'm a Senior L3 Site Reliability Engineer at Deutsche Bank in Berlin, focused on stabilizing mission-critical financial systems, cloud-native microservices, and production reliability at scale.

I spent over a decade at IAV GmbH as a Senior Software Developer, building complex automotive infotainment and HMI (Human-Machine Interface) solutions — the rich, user-facing software that drivers interact with. My focus areas:

• Android-based HMI development (AOSP)
• CI/CD pipelines and test automation
• Performance optimization and system integration
• Process & quality standards (ASPICE)

• JVM: Java, Kotlin, Groovy
• High-level: C++, .NET, PHP
• Scripting: Python
• Low-level: Assembler (x86, Java bytecode), C
• OS & systems: GNU/Linux, LAMP, WINE
• Databases & data integrity: MySQL, SQL, LMDB key–value store, error correction (ECC, FEC, RS-Codes)
• Performance: high-performance and parallel computing (OpenCL, VHDL)
• Cryptography: ECC, RSA, Diffie–Hellman, blockchain (Bitcoin, Monero, Bitmessage)
• Build & DevOps: Maven, Ant, Gradle, Jenkins
• Privacy & security: TOR, secure communication, blockchain privacy, attack-vector analysis

I care deeply about well-tested software with strong quality assurance. Across my projects I combine test-driven development with:

• Property-based testing (jqwik) and architecture tests (ArchUnit)
• Mutation testing (PIT) and code coverage (JaCoCo)
• Static analysis and null safety (SpotBugs, Error Prone, NullAway)
• Concurrency verification (jcstress, Lincheck, vmlens)

• Automotive infotainment & HMI software development
• Software integration and interface design
• Embedded development and protocol-level work
• DevOps and continuous delivery for infotainment systems
• Guest lecturer on CI/CD in automotive software

• ⚡ Certified for working on high-voltage automotive systems (up to 1000 V AC / 1500 V DC):
  Elektrofachkraft (EFffT) gem. DGUV-I 209-093 – Stufe 2E (FHV)
• 🩹 Certified first aider
• 🎓 Guest lecturer on DevOps and continuous delivery in automotive software

A high-performance JVM + OpenCL tool that generates and checks Bitcoin and altcoin addresses at scale. Built for cryptographic experiments and raw key-search throughput — with parallel EC key generation, vanity-address search, and fast LMDB lookups.

A thread-safe buffer that connects an OutputStream to an InputStream for real-time data flow between threads. Supports concurrent reads and writes, automatic buffer trimming, and optional clone-on-write safety.

Java bindings for llama.cpp that run local LLMs entirely on the JVM — text and chat completion, embeddings, reranking, and infilling, with no cloud dependency. Ships pre-built native binaries for Linux, macOS, Windows, and Android. Published on Maven Central as net.ladenthin:llama.

A Maven plugin that documents Java projects with a local llama.cpp model — no cloud required. Generates per-file and per-package .ai.md summaries with keyword metadata, and updates only the files that changed. Published on Maven Central as net.ladenthin:llamacpp-ai-index-maven-plugin.

I love working on electronics projects, exploring reverse engineering, and experimenting with low-level optimization techniques.
In my spare time, I craft utilities and microtools that blend software and hardware.

Based near Berlin, Germany, I'm passionate about well-tested, efficient, and secure software — whether it's running on a car, a GPU, or a tiny embedded chip.

I'm always happy to talk about tech, performance, or embedded systems!
