The Problem

The organization managed 100+ applications with inconsistent testing practices, low code coverage, and high bug escape rates. Bug detection was slow, quality assurance was largely manual, and application performance suffered from unoptimized code paths, resulting in slow response times on critical endpoints.

The Solution

Developed a comprehensive unit testing framework using MSTest and NUnit to standardize testing across the enterprise. Implemented automated testing strategies integrated with CI/CD pipelines. Performed code optimization and profiling to improve application performance across critical endpoints.

Implementation

Designed and implemented a reusable testing framework with MSTest and NUnit, establishing coding standards, test patterns, and coverage thresholds across 100+ applications. Integrated automated test suites into Azure DevOps pipelines to run on every build and deployment. Used profiling tools to identify performance bottlenecks and optimized code paths, database queries, and resource utilization. Maintained and improved CI/CD pipeline configurations for consistent production releases.

Technologies

.Net SQL Azure DevOps

Impact & Results

Achieved 85%+ code coverage across the enterprise application portfolio. Reduced bug detection time by 60%, significantly improving software quality. Improved response times by 35% on critical application endpoints. Accelerated release cycles through automated testing and reliable deployment processes.
