KALEOX
Real-time construction project controls platform.
Kaleox is a unified construction management platform built with Next.js 16 and a .NET 10 API. It provides real-time dashboards for budget burn-down, Gantt/kanban scheduling, material inventory with stock-in/stock-out workflows, milestone rollup tracking, blueprint annotation with pins, and SignalR-powered live updates across all modules.
Production-grade SignalR-powered real-time synchronisation deployed via Docker on DigitalOcean behind Nginx with automatic SSL (Let's Encrypt). Every stock adjustment, task status change, and daily log update propagates instantly across all connected clients without page refreshes. Features a multi-stage Docker build pipeline (14.5 MB runtime image), a Hangfire background job server for document expiry checks and recurring reports, and PostgreSQL with EF Core migrations auto-applied on container startup.
The Challenge
Construction project managers and site supervisors struggle with fragmented, paper-heavy operations — spreadsheets for budgets, whiteboards for schedules, siloed messaging for approvals. Critical information (blueprints, material requests, daily logs) lives across disconnected tools, causing delayed decisions, missed deadlines, and costly material waste.
The Solution
A centralized, real-time platform that replaces fragmented spreadsheets, whiteboards, and siloed messaging with live dashboards and SignalR-synchronized updates across every module — from budget burn-down and scheduling to inventory, milestones, and blueprint annotation.
Real-Time SignalR Dashboards
Live budget burn-down, schedule, and inventory dashboards that update instantly across all connected clients via SignalR WebSockets.
