Making weather data useful.
I build forecasts, warning systems, and practical data tools for decisions that cannot wait.

Services
Independent desk-study work for marine operations. Short scopes, clear deliverables.
Metocean desk-studiesWind, wave, and current climate for a site, including extremes where the decision needs them.
Berth and port operabilityWeather windows and downtime views for berthing, towage, and marine work at the jetty.
Port warning toolsCustom jetty dashboards and warning systems, built on the same approach as my Port Warning System.
Where relevant: ISO 19901-1, DNV guidance, OCIMF MEG4.
Working Together
How desk-study work usually runs.
- Remote desk-study100% remote. No site visit required for a typical desk-study scope.
- TurnaroundMost scopes take 3 to 5 working days once inputs are clear.
- DataOpen products (ERA5, CMEMS) plus any survey or metocean data you already hold.
- StartEmail the site, the decision you need to support, and the timeline. I reply with scope and next steps.

Benchmark of statistical and deep learning methods for HF radar surface current forecasting in the Sunda Strait.
Industrial application. Built for a narrow tropical strait where surface currents drive berthing, towing, and subsea ops risk, not only forecast skill scores.

About
Grounded in the real world.
I work at the intersection of meteorology, data, and human decisions. My day job is operational: the forecast has to be accurate, timely, and understandable when conditions change fast.
My research on AI/ML models for sea surface current forecasting in the Sunda Strait is published in ASCMO. Outside the forecast desk, I build tools and write about the systems behind useful technical work.
