The Challenge

Understanding the business context and identifying the core problems that needed solving.

The Client

CREA-E S (Regional Council of Engineering and Agronomy of Espírito Santo)

A leading organization in their sector, facing significant operational challenges that required innovative technological solutions to maintain competitive advantage and operational efficiency.

The Problem

CREA's field inspectors relied on a paper-based process, which was slow, created a risk of information loss, and made it extremely difficult to consult the history of millions of existing infraction records.

This created significant bottlenecks, increased operational costs, and limited scalability potential.

My Objectives

Given the challenges identified, I was tasked with delivering specific outcomes:

1

Digitize 100% of the field inspection workflow

2

Ensure system performance while handling a massive volume of data

3

Architect a secure and scalable solution with offline capabilities

3
Quantitative Results
3
Qualitative Outcomes

The Solution

My strategic approach to solving the challenges through innovative architecture and technology choices.

Technology Stack & Reasoning

React Native

For its agility in cross-platform development and robust offline-first capabilities, which were essential for fieldwork.

C# + .NET

Chosen for its robustness and performance in handling heavy background tasks required for the massive data load.

Hangfire

Used for asynchronous background job processing, which was critical to avoid blocking the API during heavy data operations.

PostgreSQL

Optimized for performance with complex queries across millions of records, supported by a smart indexing strategy.

Key Features Implemented

1

Offline-First Synchronization System

Allowed inspectors to work seamlessly in the field without an internet connection, with data auto-syncing when available.

2

Digital Document Processing

A complete workflow for creating, processing, and signing documents digitally, fully integrated into the app.

3

Large-Scale Optimized Search

Enabled fast queries on millions of historical records directly from the mobile app through intelligent indexing.

Results & Impact

The measurable outcomes and lasting impact achieved through strategic implementation and execution.

Quantitative Results

1

Estimated 70% reduction in report completion time

2

Maintained a 92% system uptime under heavy load

3

Historical queries completed in under 15 seconds on average

Qualitative Impact

1

Significant increase in field inspector satisfaction and efficiency

2

Complete elimination of paper from the inspection workflow

3

Improved transparency and traceability of all inspection processes
