Sabahattin Kalkan

Systems Engineer & Software Architect

I build reliable systems at the intersection of software engineering, building automation, and physical infrastructure. My work spans engineering tools, deterministic developer workflows, and software that has to remain trustworthy in real operating environments.

Selected Work

  • antigravity-fullstack-hq — An opinionated AI engineering workflow and configuration for Claude Code and Google Antigravity, with community traction.
  • Recall — Deterministic repository context for AI coding agents.
  • codediag — Deterministic engineering health and risk analysis for Node.js repositories.

Engineering

  • Building automation
  • BACnet / KNX / BMS
  • Fire & life-safety systems
  • Software architecture
  • Infrastructure & automation

Engineering Notes

  • engineering-handbook — A public operating reference for repository standards, architecture, workflow, review, security, release, and maintenance.
