Trendsic Case Study

Legacy Web App Modernization Cuts Costs and Boosts Security for California Nonprofit

Trendsic incrementally modernized Family Care Network, Inc.’s fragmented legacy web application — migrating from AngularJS and ASP.NET Web Forms to Angular, Web API, and Docker with CI/CD pipelines — reducing maintenance costs, accelerating deployments, and strengthening security without disrupting the nonprofit’s critical community services.

Trendsic custom software modernization for Family Care Network, Inc.

Client & Industry

Family Care Network, Inc. (FCNI) is a not-for-profit Community-Based Organization serving children, youth, and families impacted by trauma in San Luis Obispo and Santa Barbara counties, California. FCNI provides intensive support and services to empower vulnerable community members to live healthier lives and achieve their goals.

To deliver those services, FCNI relied on an internal web application — but that application had grown into a fragmented mix of outdated technologies: AngularJS, ASP.NET Web Forms, and ASP.NET Framework Web API. The result was an aging, hard-to-maintain platform that was costing the nonprofit too much time and money to keep running.

Trendsic was brought in to modernize the system without disrupting ongoing operations — delivering the kind of custom software modernization that gives organizations a scalable, maintainable platform for long-term growth.

The Challenge

FCNI’s patchwork of aging technologies was dragging down productivity, creating security risk, and frustrating staff with a slow, unintuitive interface.

Challenge 1

High Maintenance Costs

Keeping the system running required significant ongoing effort and expense. Outdated, incompatible frameworks meant that even routine updates demanded disproportionate developer time and resources.

Challenge 2

Difficulty Applying Security Patches

The fragmented architecture made it difficult to apply security patches in a timely manner, leaving sensitive client data and organizational systems exposed to unnecessary risk.

Challenge 3

Poor User Experience

Staff relied on the web application daily to support vulnerable families — but the aging interface was cumbersome and hard to navigate, adding friction to critical workflows and reducing the organization’s operational effectiveness.

The Solution

Trendsic modernized FCNI’s web application piece by piece, enabling a seamless migration without the risk or cost of a full rebuild.

Capability 1

Incremental Technology Migration

Trendsic modernized it module by module — migrating to Angular and Web API, and containerizing the platform with Docker and CI/CD pipelines. This approach enabled seamless integration with the existing system while avoiding lengthy parallel development, minimizing disruption.

Capability 2

Streamlined Deployments & Maintainability

With CI/CD pipelines and a modern, cohesive technology stack in place, FCNI can now deploy updates and changes faster than ever. The modernized codebase is also significantly easier to maintain — reducing the time, effort, and cost required for ongoing support.

Capability 3

Enhanced Security & Improved User Experience

The new system streamlines patching, enabling rapid response to security vulnerabilities and better protection of sensitive data, while its modern web technologies deliver a faster, more intuitive interface—improving the daily experience for staff who depend on the platform to serve vulnerable families.

This engagement reflects Trendsic’s approach to custom software modernization — modernizing legacy systems incrementally to deliver immediate value while protecting existing operations.

Results & Outcomes

Results

  • Lower Maintenance Costs: The modernized, unified codebase substantially reduced the time and cost of ongoing support.
  • Faster Deployments: CI/CD pipelines enable rapid deployment of updates and changes, ensuring services remain responsive to client needs.
  • Enhanced Security: The new system is easily patchable, allowing FCNI to address vulnerabilities promptly and protect sensitive data.
  • Improved User Experience: A modern, intuitive interface made the application faster and significantly easier for staff to use each day.

Other Benefits

  • Zero Service Disruption: Trendsic’s incremental migration approach allowed FCNI to continue serving vulnerable families throughout the entire modernization process.
  • Scalable Architecture: The unified modern stack gives FCNI a platform that can evolve alongside the organization’s growing needs without another costly replacement.
  • Protected Sensitive Data: Streamlined patching means FCNI can keep client data safe with far less overhead than the legacy system required.

Technologies & Approach

  • Angular (migrated from AngularJS)
  • ASP.NET Web API (migrated from Web Forms & ASP.NET Framework)
  • Docker containerization
  • CI/CD pipeline implementation
  • Incremental legacy system integration & module migration
  • Custom web application development
💡 Conclusion

Trendsic’s seamless integration of new technologies with FCNI’s existing applications ensured a smooth transition — allowing the organization to continue providing critical support and services without disruption. The result is a modern, secure, and maintainable platform that frees FCNI to focus on its mission rather than its technology. It’s the same kind of custom software modernization Trendsic delivers for nonprofits, small businesses, and enterprises across Louisiana and nationwide.
