Profile

Built for people who care whether the work is useful, maintainable, and calm under pressure.

I build practical AI systems that make work faster.

AI Engineer and full-stack developer focused on automation, business process optimization, and internal productivity platforms.

I work across Next.js, React, TypeScript, Python, SQL, ETL, dashboards, and self-hosted deployment to turn operational problems into usable software.

Currently building AI-powered internal applications, custom ERP workflows, and reporting automation for real business operations.

Clarity over cleverness

Automation with human verification

Outcomes over outputs

Experience as operating history.

Not a timeline decoration. A record of systems shipped in business, factory, data, and AI evaluation environments.
