Overview

Website redesign for Sealift Systems, makers of the Sealift Rescue Method for sea rescue in rough weather. HTML, CSS, PHP, and vanilla JS from 2016–2019 — explaining heavy tech to people who work on boats.

Sealift Systems develops the Sealift Rescue Method — technology built for safe sea rescue in rough weather and harsh climates. The method sets a high bar for rescuers: gentle extraction of people from the water while keeping the rescue crew safe throughout the operation.

Over two and a half years (2016–2019) I led the website redesign and front-end build — HTML, CSS, PHP, and vanilla JavaScript. No frameworks: deliberate, hand-written code for a company whose product is physical rescue equipment, not software dashboards.

The site needed to communicate complex rescue technology clearly — explain the method, build trust with maritime operators, and hold up on the devices crews actually use at sea. Constraint-heavy work that pushed me to write lean, accessible front-end code before component libraries were the default.
