Professional Experience

Stuttgart, Germany
Independent Consultant & Technical Trainer /2026 – Ongoing

• Systems Engineering Consultancy: Provide specialized research, architectural auditing, and low-level development in Rust, C++, and Assembly, focusing on high-concurrency tooling and security hardening.

• Trainer: Available for corporate seminars covering low-level kernel programming (Windows/Linux), networking (TCP/IP), and complex Rust FFI integrations.

Stuttgart, Germany
Backend Engineer – Solutions Engineering /2025 – 09/2026

• Decentralized PAM Architecture: Pioneered a novel Privileged Access Management (PAM) infrastructure by conceptualising a peer-to-peer trust model that completely eliminated architectural Single Points of Failure (SPOFs).

• Cryptographic Protocol Engineering: Designed and implemented the cryptographic backbone for the decentralized PAM ecosystem; developed a custom asymmetric key-based configuration protocol and a decentralized PKI-service to enforce end-to-end integrity and tamper-proof state synchronization.

• System Modernization & Stability: Contributed to the migration of legacy C++, Erlang, and TypeScript services to a high-performance Rust-based microservice architecture, optimizing for high-concurrency environments (>200K RPS) and strict sub-100ms latency guarantees.

• Enterprise Product Leadership: Acted as a technical lead for complex enterprise requirements, managing the full lifecycle from requirement engineering and protocol specification to the delivery of scalable IAM and fraud mitigation services.

Stuttgart, Germany
Systems & Security Engineer /2024 – 03/2025

• Low-Level Kernel Engineering: Developed system-level drivers and modules interacting with the Windows kernel using Rust and C++. Performed deep-dive binary analysis and low-level debugging of core operating system architectures.

• Enterprise Platforms: Architected a highly scalable sales, user, and license management infrastructure with integrated international payment gateways and automated client software lifecycle deployment.

Global
Research /2024 – Ongoing

• Threat Emulation Framework: Architected and engineered an advanced network resilience and threat emulation platform ("Actrax") in Rust and C++ to evaluate detection engineering capabilities and endpoint defense mechanisms.

Remote
Offensive Tooling & Compatibility Engineering /2023 – 08/2024

• Mass Deployment & Compatibility (05/2024 - 08/2024): Deployed and maintained custom software for a global user base, ensuring continuous runtime stability across hundreds of volatile Windows OS builds and custom hardware environments.

• Mission-Critical Infrastructure Utilities (12/2023 - 04/2024): Engineered a custom suite of infrastructure health utilities and configuration verification tools designed to validate environment states and ensure maximum availability in high-security, sensitive deployment environments.

• Reverse Engineering & Integrity Bypasses (03/2023 - 11/2023): Analyzed complex security mechanisms and runtime protections using IDA Pro and WinDbg to evaluate functional software integrity and binary execution flows.

Technical Training

Stuttgart, Germany
Specialized Technical Curriculum Delivery /2026 – Ongoing

• Networking & Protocol Seminars: Deliver comprehensive training tracks covering Foundational Networking & TCP/IP for beginners, extending up to deep-dive Advanced TCP/IP Stack Analysis and specialized enterprise network infrastructure seminars.

• Windows Operating System Internals: Conduct deep-dive courses spanning Windows System Programming, core Windows Internals architectures, and premium developer tracks covering Windows Kernel Programming and driver development.
