I build pragmatic developer tools that make complex systems easier to understand, maintain, and use — from enterprise integrations and SQL analysis to documentation and Free Pascal libraries.
I work with Free Pascal, Python, SQL, R, and HTML/CSS/JavaScript.
Integration Atlas — Map dependencies across scripts, databases, files and APIs, with evidence-backed relationships and change-impact analysis. Local-first by design.
No installation, no account — and your data never leaves your browser.
- SQL Cartographer — Explore SQL control flow, dependencies, lineage and ERDs.
- Git Map — Learn Git branching, merging and recovery in a visual sandbox.
- PromptCurtain — Mask sensitive details before sharing prompts with AI.
- First-Pass Triage — Get explainable P1–P4 suggestions for support tickets.
- Quiet Response — Generate custom QR codes privately.
Zero third-party runtime dependencies, tested on Windows and Linux. The most-used are pinned below.
