About Me
Software developer and consultant with 10+ years of experience building applications, trading tools, and content systems. I run Arketos Integrations, a boutique agency serving blockchain and technology clients with development, content strategy, and growth services.
I use Claude Code daily — it's how I ship faster and build better. I've worked with clients ranging from early-stage startups to projects with billion-dollar market caps.
Background includes iOS development (Swift), JavaScript/Node.js, React Native, Python, and technical content creation. I've published 587+ YouTube videos and helped clients generate six-figure revenues through strategic content.
I believe AI amplifies what good developers can do. Looking to join a team pushing that vision forward.
