Reviving a Digital Banking Sitefinity Project for a Major Bank in Australia and New Zealand

Critical Sitefinity Project in Crisis Following Breakdown with Previous Partner

Critical Operational Issues Left by Previous Partner

The bank was facing urgent, pressing issues following a breakdown in their relationship with a previous development partner, creating a critical situation that was directly affecting their operations and customer experience.

Security and Accessibility Vulnerabilities

The existing Sitefinity implementation had unresolved security vulnerabilities and significant accessibility issues — including problems with screen readers, form fields, and dropdowns — that needed immediate attention to protect customers and meet compliance requirements.

Deployment, Performance, and Integration Failures

The project was suffering from deployment caching issues, production environment problems, Node.js and NPM conflicts, and unreliable API integrations that were undermining the stability and reliability of the entire banking platform.

Full Sitefinity Stabilisation Covering Security, Accessibility, APIs, and Code Quality

Security Hardening and Custom Authentication

Eveliko implemented a tailored authentication system to enhance security and streamline user access, and conducted penetration tests to identify and resolve security vulnerabilities — including rate limiting functionality to protect customer data.

Accessibility and Form Improvements

Accessibility issues across screen readers, form fields, and dropdowns were identified and resolved. Form layouts, validation logic, and usability were also optimised to prevent user errors and improve the overall customer experience.

Debugging, Deployment, and Environment Stabilisation

The team thoroughly investigated and resolved deployment caching issues, production environment failures, and Node.js and NPM conflicts — restoring a stable, smoothly functioning environment and developing custom tools to accelerate future troubleshooting.

API Integration and Code Refactoring

API integrations were improved to enhance data accuracy and flow between systems, while existing code was reviewed and refactored for improved readability, maintainability, and performance.

Documentation, Knowledge Transfer, and Ongoing Collaboration

Eveliko documented all solutions, best practices, and troubleshooting steps to empower the bank's internal team to manage future challenges independently, supported throughout by regular sync meetings and transparent communication.
