From an idea to a system that just works.

I connect human intent, engineering craft and the intelligence underneath.

I BUILD THE EXPERIENCE. AND THE INTELLIGENCE BEHIND IT.

SOFTWARE ENGINEERING

  • Desktop PlatformsElectron, JavaFX and Swing apps with local-first data.
  • Full-Stack WebNext.js, React, Node.js and solid APIs.
  • System ArchitectureData models and real-time bridges that stay predictable.
  • Product EngineeringFrom first flow to final release, with no bloat.
  • Developer ToolingHotkey utilities, installers and automation.

AI SYSTEMS

  • Applied AIGenerative features that solve real product problems.
  • Computer VisionCUDA-accelerated super-resolution and image understanding.
  • AI AutomationTurn repeated work into reliable workflows.
  • Prompt DesignClear instructions that make models dependable.
  • Intelligent InterfacesModel behaviour that is legible and controllable.

EVERY SYSTEM CARRIES A HUMAN IMPRINT.

Mine comes from understanding the person on the other side of the screen, shaping how things feel, and building the engineering that makes them work.
