Design & build a suite of modern web apps connecting core banking platform to member-facing experiences.

Like many credit unions of its scale, DFCU operates Temenos as its core banking platform; a system historically built around branch-connected, desktop-based workflows. As member expectations shifted toward digital-first service and competitive pressure from regional banks and fintech players grew, DFCU needed to translate core banking capabilities -- account opening, loan applications, certificate promotions, and loan status tracking -- into modern, consumer-ready web experiences.

DFCU's internal development team was primarily staffed for maintaining legacy C# applications and lacked the capacity to build and sustain a new application layer in parallel. The organization also had no automated deployment pipeline so every release required manual intervention, and there was no staging environment for the back end, meaning development work went directly to production. These conditions made shipping new consumer features both slow and risky. At the same time, a single Head of Product was carrying both UI/UX design and product management responsibilities simultaneously.

DFCU needed a team that could absorb ambiguity, ship consistently, and contribute engineering maturity that the internal team had not yet built; without the cost or time investment of hiring senior Next.js engineers from scratch.

Admios embedded two front-end engineers as DFCU's primary development capacity for its new Next.js application layer.

From the start, the team went beyond feature work: one engineer resolved a complex LDAP authentication bug in the initial setup and established DFCU's first automated CI/CD pipeline — GitHub Actions deploying to Linux servers, a practice the organization had not had before. Over the engagement, the team built and shipped a portfolio of applications on top of DFCU's Temenos infrastructure:
* OIW (Online Individual Web), the primary account opening experience now in its fifth major version;
* a full online loan application with Plaid-powered funding and Twilio SMS two-factor authentication;
* OIW In-Branch, a kiosk-adapted account opening flow for physical locations;
*internal tools for certificate promotion management and server health monitoring; and
*a consumer loan status tracker currently in development.

The team operates with a degree of ownership unusual for an embedded engagement. Engineers hold direct Linux server access, manage Nginx configuration, proactively patched a high-severity Next.js vulnerability before DFCU's own security tooling flagged it, and cleaned up a fragmented Google Analytics setup that had been duplicating events across environments. Standups migrated from synchronous Zoom calls to an async channel format — at the team's suggestion.

In under three years, the team:
* shipped five major versions of the primary account opening experience,
* launched a complete online loan application with integrated identity verification and SMS authentication,
* built the in-branch account flow, delivered internal tools for certificate promotion management and server health monitoring, and
*is actively delivering the consumer loan tracker.

Collectively, these represent the core of DFCU's consumer-facing digital infrastructure.

Beyond the delivered applications, the Admios team has introduced practices that have compounded in value over time. DFCU went from no automated deployment pipeline to a GitHub Actions-based CI/CD workflow that now governs all new application releases. Analytics infrastructure that had been duplicating measurement events across environments was refactored into a clean, environment-aware setup. When a critical vulnerability was disclosed in Next.js, the Admios engineer identified the issue independently, coordinated a fix across all environments, and confirmed resolution before DFCU's internal security tooling had flagged the problem; the kind of ownership that is difficult to buy and harder to teach. The engagement is now approaching three years and continues to expand as DFCU's digital application roadmap grows.
