Arpita Hajra led a full cloud-native overhaul of a digital evidence management system, reducing processing time by 40% and enhancing scalability with AWS serverless architecture. Her automated testing framework and stakeholder-driven design ensured high performance and adoption, setting a new benchmark in digital transformation for public safety systems.

This audio is presented by Hacker Noon, where anyone can learn anything about any technology. Transforming Digital Justice. Arpita Hara's Cloud Native Leadership in Evidence Management, by Sonia Kapoor. In an increasingly digital world where law enforcement agencies face mounting challenges in managing electronic evidence, the successful transformation of a critical digital evidence management tool stands as a powerful example of innovative leadership and technical excellence. Under the guidance of delivery led RP to Hara, this ambitious cloud migration project has established new standards for performance, scalability, and reliability in digital evidence processing systems.

The project, undertaken for a prominent safe and smart cities division, involved the complete rebuilding of a mission-critical platform into a cloud-native, serverless, single-page web application. This sophisticated system processes and indexes substantial volumes of evidentiary files, including video, audio, and images, serving the complex needs of local, state, and federal agencies across multiple jurisdictions. The technology overhaul addressed growing concerns about processing speed, scalability, and integration capabilities that had become increasingly apparent in the legacy system as digital evidence volumes continued to expand exponentially. At the helm of this transformation, Arpita Hara demonstrated exceptional technical vision and leadership capabilities.

She architected the AUS environment from the ground up, establishing a robust foundation for the modernized platform. Managing a talented team of over 20 professionals, Hara orchestrated the migration and re-engineering of legacy middleware into an advanced AWS Lambda and Step function-based architecture, a significant technical achievement that demanded both depth of cloud expertise and breadth of system integration knowledge. Hara's approach to this complex challenge was methodical and comprehensive, she began with a detailed analysis of the existing system's limitations, followed by the creation of a strategic roadmap for migration that minimised disruption while maximising performance gains.

By implementing a phased transition approach, she ensured that critical evidence processing capabilities remained de-operational throughout the migration process, a crucial consideration for agencies that rely on continuous access to digital evidence for ongoing investigations. Perhaps most notably, HARA designed and implemented an automated feed testing framework that enabled precise comparison between legacy and new data pipelines. This innovative testing approach encompassed approximately 200 transformations across 20 different file types, with data refreshed up to 10 times daily, creating a comprehensive quality assurance mechanism that ensured data integrity throughout the migration process.

This testing framework not only validated the accuracy of migrated data but also provided metrics that guided continuous optimization efforts throughout the project lifecycle. The impact of this leadership extended well beyond the technical implementation. Through strategic architectural decisions and operational excellence, the project achieved a remarkable 40% reduction in processing time for evidence files, a critical improvement for agencies where timely access to digital evidence can significantly impact investigations. The shift to serverless AWS components, including S3, DynamoDB, Elasticsearch, and MediaConvert, delivered substantial improvements in both scalability and reliability, essential qualities for a system handling sensitive evidentiary data. The architectural choices made under Hara's guidance yielded multiple benefits. essential qualities for a system handling sensitive evidentiary data.

The architectural choices made under Hara's guidance yielded multiple benefits. The serverless approach eliminated previous infrastructure management burdens while dramatically improving the system's ability to scale dynamically in response to fluctuating workloads. This capability proved particularly valuable during high-profile investigations that generate sudden spikes in evidence processing requirements. Additionally, the modular architecture facilitated easier updates and enhancements, positioning the platform for sustainable long-term growth. Efficiency gains were equally impressive on the development side, with Harris Automated

testing framework accelerating quality assurance cycles by 30%. This improvement not only reduced development costs but also enabled faster iteration and feature delivery, enhancing the platform's value to end users. The streamlined development process allowed for more responsive feature updates and security enhancements, creating a more agile technology ecosystem that could adapt quickly to evolving agency requirements. Stakeholder management played a crucial role in the project's success. HARA established effective communication channels with both technical teams and and user representatives,

ensuring that practical operational needs informed technical decisions throughout the development process. This collaborative approach fostered strong buy-in from law enforcement personnel and technology administrators alike, facilitating smooth adoption of the new platform. Arpita Hara brought exceptional credentials to this challenging project. With an MBA from Wake Forest Schools of Business complementing her Bachelor of Engineering from the University of Mumbai, she represents the ideal blend of technical expertise and business acumen.

Her certification as a Six Sigma Greenbelt reflects her commitment to operational excellence and process optimization, qualities that proved invaluable in navigating the complexities of this transformation initiative. As a visionary technology leader based in Raleigh, North Carolina, Hara has established herself as an authority in cloud architecture, digital transformation, and enterprise technology implementation. Her technical proficiency spans multiple domains, including AWS, GCP, DevOps tools, and various enterprise applications, a versatile skill set that enabled her to address the multifaceted

challenges of this project. This success story illustrates how strategic technical leadership, when combined with deep cloud expertise and innovative testing methodologies, can transform critical operational systems. The Digital Evidence Management Tool project not only modernized an essential platform for law enforcement agencies but also established new benchmarks for cloud migration projects in high-stakes environments. Looking forward, the implications of this successful implementation extend beyond immediate operational improvements. The modernized platform now provides a foundation for future capabilities, including potential integration with emerging technologies such as artificial intelligence for evidence analysis

and machine learning for pattern recognition in large evidence datasets. The architectural framework established under Hara's leadership positions the system to evolve alongside advancing investigative techniques and technologies. As digital evidence continues to grow in both volume and importance within the criminal justice system, this project stands as a compelling example of how focused leadership can drive exceptional results in digital transformation initiatives. Through her commitment to excellence and ability to bridge technical and business perspectives, Arpita Hara has demonstrated how

visionary leadership can deliver transformative results in even the most challenging technical environments.
