Backend & Platform Engineering
Expertise in designing and building company-wide internal software platforms from scratch, covering database design, backend APIs, authentication, authorization, caching, complex SQL, query optimization, and asynchronous data processing using PHP, Python, C#, .NET, MariaDB/MySQL and REST APIs.
Infrastructure & DevOps
Hands-on experience with Linux server administration, Nginx, Docker, GitLab CI/CD, networking, firewalling, VPNs, TLS, backups, monitoring, deployment and production troubleshooting, including full ownership of production infrastructure.
Frontend & Web Development
Proficiency in building modern web applications using Vue 3, Vite, TypeScript, JavaScript, HTML, CSS, PWA and Service Workers, including near-real-time reporting dashboards and multi-module enterprise frontends.
Industrial & Embedded Systems
Experience with PLC integration, industrial software, firmware development, RFID systems, custom camera systems, IoT devices, Android application development and robotics infrastructure using ROS and Open-RMF.
Identity & Security
Implementation of modern authentication and identity layers including WebAuthn/passkeys, Microsoft account integration, standards-based authentication, fine-grained role and permission management, and secure session and credential handling.
AI & Agentic Systems
Building and experimenting with local and cloud-based multi-provider agentic development environments, including agent orchestration, task decomposition, validation gates, result verification, context management, custom compaction and local inference.
Programming Languages
Proficiency in C, PHP, TypeScript, JavaScript, Python, C#, .NET, SQL, C++ and low-level/assembly programming.
Smart Metering & Communication Protocols
Development of software for smart-metering products, implementation of European smart-meter communication protocols, cryptographic key exchange/distribution and performance improvements to backend infrastructure for meter communication validation.
Data Migration & Serialization
Design and implementation of internal migration and conversion tools for complex document structures across incompatible software generations, including reverse-engineering of differences between generations and serialization/data-processing optimizations.

Projekthistorie
Architected and built a company-wide internal software platform from scratch, growing it to 20+ operational modules and 100+ concurrent users across sales, procurement, laboratory work, concrete production and internal administration. Owned the entire system lifecycle including database design, backend APIs, Vue/TypeScript frontend, authentication, Linux servers, Nginx, Docker, GitLab, CI/CD, networking, firewalling, VPNs, backups, monitoring, deployment and production support. Built near-real-time sales and management reporting, a multi-country public-procurement ingestion system, a meal-ticketing and point-of-sale system, firmware and software integration for custom camera systems, and became responsible for production infrastructure operations.
Developed and maintained C#/.NET software for industrial production systems, including communication with PLC-controlled machinery and processing of machine data. Designed an internal migration/conversion tool for PLC specification and instruction documents stored as XML across incompatible software generations. Worked on serialization and data-processing optimizations and developed internal software for managing application translations.
Developed software for smart-metering products and associated infrastructure. Implemented a European smart-meter communication protocol for communication with meters over the wire. Worked on performance improvements to backend infrastructure for validating meter communication and handling cryptographic key exchange/distribution. Implemented product features, produced functional prototypes and participated in architecture, verification, testing and investigation of product deficiencies.
