Our Work

Problems solved.

Real tools built for real problems in the field.

Case Study

Infrastructure Damage Intelligence

A regional broadband provider was losing critical hours between damage identified in the field and resolution in the back office. Meanwhile, neighbors were already posting about outages on social media. Field crews had no reliable way to document and escalate what they were seeing. Operations teams had no real-time picture of what was happening on the network.

We identified the gap and built the solution: Clearwire, a closed-loop infrastructure damage intelligence platform that connects field crews and operations teams from the moment damage is reported to the moment it's resolved.

The Problem

Damage identified in the field. No reliable way to document, escalate, or track resolution. Operations flying blind while customers were already aware of outages.

The Solution

A mobile-first field reporting platform that captures damage, routes it to the right people, and tracks resolution from report to close. One platform, every stakeholder.

The Outcome
Faster response from field report to dispatch
Real-time visibility for operations teams
Complete audit trail from damage to resolution
One closed loop: field crews and back office aligned
Case Study

Field Operations, End to End

A telecom contractor was running field operations on a patchwork of spreadsheets, Google Drive folders, PDF maps, Excel fiber charts, text messages, and emails. Job data lived in six different places and moved slowly. When a technician completed work in the field, everything needed to turn that completion into an invoice had to be manually hunted down and assembled. The process routinely took weeks.

We replaced the entire system with a single custom app built for the way their crews actually work, capturing job details, location, work performed, and documentation the moment a technician wraps up. The back office gets everything they need in real time.

The Problem

Job data scattered across six disconnected tools. Technicians finishing work in the field with no reliable way to close the loop. Back office waiting days or weeks to assemble what they needed to invoice.

The Solution

A custom mobile-first app that captures everything the moment a job is complete, automatically pushing data to as-built records, job folders, and back-office systems. No manual filing. No follow-up emails.

The Outcome
Work-complete to invoice: several weeks down to 3 days
As-built and job folders built automatically on submission
Back office notified the moment a tech wraps up
Payroll-ready data without the manual assembly

Marketing Sites for the Specialist Trades

Most off-the-shelf website templates assume a business is selling to walk-in customers. Specialist contractors (fiber, telecom, structured cabling) sell to buyers who vet on craft and credentials, not stock photos. We design and build marketing sites that lead with the work.

We built a complete demonstration site around OptiCore Infrastructure, a fictional fiber contractor brand, so prospects can see the kind of layout, copy, and visual system we can deliver for a real business in the trade.
