The Challenge

Managing luminaire maintenance at scale is a complex, ground-level operation. Optima Energia needed a system that would give their field technicians visibility into which luminaires required maintenance, allow them to log and track service work in real time, and submit product requests for parts and supplies — all from a mobile device while on-site.

The key constraint: field workers often operate in areas with unreliable or no internet connectivity. Any solution had to work offline and sync reliably once a connection was restored. A standard cloud-dependent app wasn't an option.

‍

The Solution

Axented designed and built a native iOS application and a supporting API to power Optima Energia's field operations from the ground up.

‍

iOS App (Swift)
A purpose-built mobile tool for field technicians, featuring:

• Luminaire inspection and status tracking
• Maintenance work logging and progress tracking
• Product and supply request submissions
• Offline-first architecture with local storage and automatic sync when connectivity is restored

API & Backend (Ruby on Rails + PostgreSQL + AWS)
A robust backend powering the mobile app, providing:

• Centralized data management for luminaire inventory and maintenance records
• Sync logic to handle data written offline and reconcile it on reconnect
• A reliable, scalable foundation hosted on AWS

Project Management
The engagement ran on bi-weekly sprints managed in Jira, with daily standups for the technical team — keeping a lean four-person team aligned and shipping consistently across a focused six-month timeline.

Services Provided

• Mobile App Development (iOS / Swift)
• API & Backend Development (Ruby on Rails, PostgreSQL, AWS)
• UX/UI Design
• Technical Consulting & Architecture

‍

The Results

With the new system in place, Optima Energia's field teams gained the tools to work faster and smarter:

• Higher luminaire coverage — technicians were able to inspect and service more luminaires per shift with structured digital workflows replacing manual or paper-based processes.
• Full maintenance visibility — supervisors gained real-time tracking of ongoing and completed maintenance work across their fleet.
• Reliable offline operation — the local-first architecture ensured field workers were never blocked by connectivity issues, with data syncing automatically in the background.
