Case Studies & Deep Dives

Proof of Work

Deep, verifiable systems built to untangle messy operations, enforce security protocols, and generate real operational revenue.

Multi-Tenant Telecom Operations Platform
01/Telecom Industry (United States)

Multi-Tenant Telecom Operations Platform

The Challenge

AAA Data Solutions needed a centralized platform to manage organizations, properties, telecom services, onboarding, porting, E911 compliance, and client support across its operations.

What I Built

Designed and developed a dual-sided platform where internal admins can manage organizations, properties, services, onboarding, porting, E911, and support workflows, while client organizations get a dedicated view of their assigned properties and operational information. The system was structured around role-based access, multi-tenancy, and organization-level data separation to support different admin and client workflows.

What Changed

Turned a collection of operational processes into one centralized platform — giving internal teams a single place to manage client operations while giving organizations a dedicated portal for their own data and support requests.

Operations & Invoice Management Platform
02/Logistics Industry (Canada)

Operations & Invoice Management Platform

The Challenge

A Canadian logistics business was dealing with a manual, document-heavy workflow for managing and verifying operational invoices, making it difficult to consistently validate billing information before payment.

What I Built

Built a web-based platform to centralize the invoice verification workflow, allowing the team to process, review, and validate invoice information through a structured digital interface instead of relying on fragmented manual processes. The system was designed around the company's existing operational workflow, with dedicated views and backend logic for handling invoice data and verification.

What Changed

Turned a manual invoice-processing workflow into a centralized digital system, giving the operations team a more structured and repeatable way to review billing information before it moves forward.

Aviation Inventory & Work Order Management System
03/Aviation Maintenance (United States)

Aviation Inventory & Work Order Management System

The Challenge

Aviation maintenance operations required a structured way to manage inventory and maintenance work orders while keeping track of parts, tools, and the status of ongoing maintenance activities.

What I Built

Built an aviation-focused inventory and work order management system that centralized part and inventory records, supported work order creation and tracking, and connected maintenance activities with the resources required to complete them. The system was designed around the operational workflow of an aviation maintenance environment, rather than a generic inventory-management model.

What Changed

Replaced fragmented inventory and maintenance tracking with a centralized system, giving the team a clearer view of available resources, work orders, and maintenance activity in one place.
