Senior DevOps engineer and founder of InfComTec, active in ICT since April 1984 (). Experience spans CP/M, DOS, every major Windows and Linux generation, and all principal cloud platforms. Focus on on-prem, secure, reliable systems—design, deployment, and expert consultation. Rotterdam-based, Dutch Chamber of Commerce: 27304499.
High-availability file and print server for on-prem environments.
- Debian, DRBD, Samba, CUPS, custom management.
- Two-node system; data kept in sync block-level.
- Only one node connects to LAN at a time—quorum is enforced physically (network cable swap, dual-NIC per node).
- No network split-brain risk. Designed for reliability, transparency, and straightforward recovery.
Engineered a model-agnostic, prompt-native method for full session state persistence with LLMs.
- “Session space” is maintained across runs by serializing prompt trajectories and operational context as replayable text artifacts.
- No model modification, tooling, or architectural change required.
- Enables reproducible, agentic workflows, deterministic state restoration, and portable “prompt-as-runtime” operations across any LLM platform.
- Bridges the practical gap between stateless generative models and real-world stateful applications.
Robust network edge device for secure home and SMB segmentation.
- Debian on dual-NIC mini PC.
- Uses common, trusted tooling (DnsMasq, DHCP).
- Focus on simplicity, auditability, hardened defaults.
- Designed for clarity at the private LAN / Internet boundary; under active development.
A dev-time-only introspection and automation server linked into any Java Swing application.
- Exposes the live component tree plus java.awt.Robot input and screen capture over plain HTTP/JSON.
- Lets an agent or test harness click, type, drag and screenshot a real desktop app — no xdotool, no pixel-guessing.
- The Swing equivalent of what Playwright is for the browser; measured roughly 15× faster smoke tests on a real external project.
A single-source-of-truth library consolidating utility code scattered across dozens of personal repositories.
- Colour science, imaging, geometry/mesh, statistics, Swing helpers, CLI argument handling and more, each with provenance notes.
- Distribution by deliberate file copy rather than an artifact repo — DRY without the operational weight of Maven Central.
- Fixes always originate in the catalog and propagate outward; downstream copies never drift.
