About me

Senior Software Engineer & AI Solutions Architect

Today, my focus is on AI integration, agentic systems and software teams’ development practices. At Augmentry, I work on AI and software projects from clarifying requirements through architecture and implementation to rollout.

I combine hands-on engineering with software architecture and team leadership. For a B2B invoicing platform in the UAE, I assembled and led the team and took responsibility for the entire development process, from planning and stakeholder alignment through architecture and implementation to delivery. Together, we integrated OCR, process automation and a digital assistant based on a fine-tuned open-weight LLM.

This builds on my software experience since 2013: SaaS products, industrial data processing and connected devices. At SEW-EURODRIVE, I worked on a predictive maintenance platform using neural networks; at Bruker, I contribute to hardware interfaces and systems integration. Today, I also develop my own tools for coding agents and share practical methods through technical writing and my ongoing training collaboration with ObviousWorks.

Work experience

06.2023 to Present

Bruker AG

Senior Software Engineer

At Bruker, I develop components for hardware interfaces, systems integration and real-time data processing in networked NIR instrument software. My work connects device communication with measurement workflows, using React, Electron and C++.

06.2026 to Present

Augmentry

Founder

As the founder of Augmentry, I work with teams and stakeholders to turn business requirements into AI and software applications. I cover discovery, architecture, implementation and rollout. My focus includes agentic systems, retrieval-augmented generation, self-hosted language models and their integration into existing applications.

07.2022 to Present

Blank IT Solutions & Consulting

Freelance IT Consultant

I advise companies on software architecture, systems integration and technical modernization. I clarify requirements, assess existing systems and develop practical plans for implementation and production infrastructure.

09.2019 to 03.2023

SEW-EURODRIVE GmbH & Co KG

Full-stack developer

At SEW-EURODRIVE, I developed components for data acquisition, analysis logic and the application used by maintenance teams. The predictive maintenance platform connected vibration analysis and neural networks for failure detection with existing production processes.

06.2013 to 08.2019

Echobot (now Leadfeeder)

Full-stack developer

At Echobot, my work spanned application development, machine learning and software operations. I developed CRM and contract software, alongside components for web crawling and online content analysis. As part of the engineering team, I played a key role in training a neural network to classify text and identify sales-relevant signals in company information. My work later expanded to containerized services, CI/CD, infrastructure as code and monitoring.

Agentic AI & agentic development

I develop tools for coding agents and deliver training with ObviousWorks as part of an ongoing collaboration. I teach practical methods for context engineering, permissions and work in existing codebases. My skills also include agent orchestration and multi-agent systems.

Training and knowledge transfer

AI integration & automation

I connect AI capabilities with business applications, from architecture to implementation. For a B2B invoicing platform, I led the team that implemented OCR, process automation and a digital assistant based on a fine-tuned open-weight LLM.

AI integration in the invoicing platform

LLM applications & knowledge systems

My skills include retrieval-augmented generation (RAG), embeddings, reranking and vector databases such as pgvector and Qdrant. These methods connect language models with relevant data and knowledge sources.

Methods and technologies

Model training & machine learning

At Echobot (now Leadfeeder), my engineering work connected web crawling and machine learning. As part of the engineering team, I played a key role in training a neural network for text classification and the detection of sales-relevant company signals. Further ML experience comes from predictive maintenance at SEW-EURODRIVE. My fine-tuning skills include QLoRA and Unsloth.

Model training for lead detection

AI infrastructure & connected systems

My skills cover self-hosted LLMs, inference with vLLM and Ollama, LLM evaluation and monitoring. My work on industrial software provides practical experience with hardware interfaces and networked applications.
