Welcome to my personal site featuring my professional profile, maker projects, and resume.
View ResumeProfile
I am a driven Senior Software Engineer, Architect, and Coach with a passion for the full code lifecycle. My focus lies on:
- Software Architecture & DDD: Translating complex domains into robust, scalable, and team-enabling architecture.
- AI in Software Engineering: Research and development of AI-tool-agnostic agents, local LLMs, and AI skills.
- Automation (CI/CD): Optimizing the software delivery process and developer experience.
- Coaching & Mentoring: Guiding engineers and providing specialized CI/CD training to elevate teams.
Hobbies & Projects
When I am not designing software architectures or building systems, I am an enthusiastic maker and hardware tinkerer:
- Soldering & Keyboards: I run a hand-soldered Lily58 wireless split keyboard from splitkb with a self-designed and 3D-printed housing. For electronics work, soldering, and rework, I use an Aoyue hot air rework station and a Pinecil V2.
- 3D Printing: I run a custom 'Frankenstein' Ender 3 Pro with OctoPrint for prototyping, printing enclosures, and functional parts.
- Homelab: I run several Raspberry Pis and an RK3588 NAS kit, all running in custom 10" housings mounted inside a 10" rack.
- Sports: Track & field and running.
