Overview

Engaged through Crayon for end client Bahri Ship Management, I built an application that monitors and improves cargo-vessel performance using real-time telemetry. The platform ingests vessel data, surfaces performance KPIs through Power BI, and runs on AWS infrastructure provisioned with CDK.

The Problem

Cargo-vessel performance data was hard to monitor in real time

Fleet operators needed actionable KPIs, not raw telemetry

Performance issues were difficult to spot and act on quickly

Telemetry came from systems with their own API rate limits

Maritime operations demanded reliable, continuous monitoring

The Solution

Real-time telemetry ingestion and processing

Vessel-performance dashboards and KPIs in Power BI

Power Automate flows for threshold alerts and scheduled report distribution

Rate-limit-aware consumption of upstream telemetry APIs

A Node.js backend with a React front end for operators

AWS infrastructure provisioned as code with CDK
