The Challenge

  • Data Accuracy & Reliability:Ensuring up-to-date, accurate inmate records for case-critical decisions.
  • System Interoperability: Integrating seamlessly with diverse legal case management platforms.
  • Security & Compliance:Protecting sensitive legal and personal data during access and transmission.
  • Real-Time Performance:Managing the high-load demands of instant query and retrieval processes.
  • User-Friendly UX:Making the interface intuitive enough for non-technical legal professionals.

The Opportunity

For law firms handling criminal justice matters, timely and reliable inmate data is essential. Traditional retrieval methods from the TDCJ system are manual, slow, and often error-prone. CoxLaw set out to modernize this process—creating a web application that integrates TDCJ data directly into legal workflows, significantly improving speed and reliability.

Our Solution

We built a high-performance, secure, and scalable web application tailored for legal research professionals. The system integrates directly with TDCJ’s data feeds and includes a robust backend to process, manage, and visualize inmate information in real time.

Key Implementations:

  • TDCJ Data API Integration: Enables lawyers to search by inmate ID and instantly retrieve structured, up-to-date information.
  • Secure Database & Authentication: OAuth2-based API protection, hosted on AWS EC2 with strict firewall policies.
  • Realtime Document Syncing: AWS Lambda functions sync case documents from S3 buckets to local environments.
  • Custom UI for Law Firms: Built on React.js, the frontend is designed for quick lookups, saved histories, and intuitive navigation.
  • Cloud-Based, Scalable Infrastructure: MongoDB, NGINX, and AWS services ensure low-latency performance across devices.
