You have a problem.
I build the fix.

17 years of turning messy data, broken workflows, and vague ideas into working software that people actually use. I've been a solo developer running a production SaaS, a lead dev managing enterprise rewrites, and the guy who figures out how to make AI useful in regulated industries. I don't just write code — I understand the problem first, then build the right thing.

Custom Web Apps

React, TypeScript, full-stack builds from concept to deploy. Dashboards, internal tools, client-facing products — whatever the problem calls for.

AI & ML Integration

Risk scoring, classification models, and AI-powered tooling — especially for compliance, finance, and data-heavy industries where getting it wrong isn't an option.

Data & BI Solutions

Qlik dashboards, ETL pipelines, API integrations, and turning raw data into something your team can actually act on. If it involves data, I've probably built it.
