Our Enterprise Modernization Process
A progressive, low-risk front-end modernization model designed for banks, insurers, enterprise SaaS and government platforms. We modernize the experience layer and the integration boundary while respecting your existing cores — AS/400, mainframe, monoliths, host screens, SOAP services or legacy HTML & JSP applications.
Technical Audit & UI/UX Diagnosis
We begin with a joint technical and UX audit together with your architecture, security and business stakeholders. The purpose is not just “reviewing screens”, but understanding how channels actually talk to your core: AS/400 transactions, tramas, batch jobs, middleware, ESB, queues and HTML or desktop front-ends that have been in place for years.
We map user journeys to the underlying systems, identify where the front-end is tightly coupled to the core and where we can safely insert an intermediate layer. The output is a modernization backlog that fits your constraints instead of a generic “rewrite everything” proposal.
- Inventory of channels, modules, screens and technical dependencies.
- Analysis of current front-end stack (HTML, JSP, JSF, jQuery, WinForms, etc.).
- Review of API contracts, tramas, host calls and integration patterns.
- UX, accessibility and performance diagnostics on real business flows.
- Risk map and prioritization of journeys with highest business impact.
Target UX, Architecture & High-Fidelity Prototype
With the audit in place, we define the target front-end architecture (SPA, modular front-end or microfrontends) and redesign the key journeys using modern interaction patterns and WCAG 2.2 AA accessibility. The prototype is not “marketing UI”: it already respects field formats, validations, error states and constraints required by your core.
Each screen is documented with expected inputs/outputs and mapped to concrete services, tramas or operations so that your technical leaders can validate feasibility before any refactor starts. This reduces rework and gives architecture, risk and compliance teams full visibility early in the process.
- Redesigned flows mapped explicitly to existing backend transactions.
- Component-ready layouts anticipating modular or microfrontend evolution.
- Design tokens (colors, spacing, typography, states) shared with development squads.
- Technical annotations on validations, edge cases and error handling.
- Formal sign-off from IT, Risk, Compliance and Business before implementation.
Front-End Refactor & Integration Layer
We then rebuild the presentation layer using React, Angular or Vue with a TypeScript-first approach. Instead of forcing changes to your core, we introduce a dedicated integration layer (BFF / API adapter) that translates between the modern front-end and your legacy contracts — JSON on one side, tramas, SOAP or fixed-length messages on the other.
We apply the Strangler Fig pattern to allow legacy and modern UIs to coexist while we migrate module by module. Internal squads can also participate: we can work as an autonomous stream, as a reference squad or embedded with your existing teams.
- Component-driven architecture with clear boundaries and state management.
- Backend-for-Frontend (BFF) and adapter layer to decouple UI from core protocols.
- Strict TypeScript typing and shared API/interface contracts with your engineers.
- Unit, integration and E2E tests integrated into your CI/CD pipelines.
- Coexistence strategy for legacy and modern UIs during the transition period.
Progressive Deployment & Shadow Releases
Deployment follows the same governance you already use: multiple environments, CAB, release windows, approvals and checklists. We deploy the new UI in shadow mode first, hitting the same services as the legacy UI, so behaviour can be compared without impacting end users.
Rollout to production users is controlled with feature flags and routing rules (by role, region, segment or branch). Every step is observable and reversible, so your teams keep operational control at all times.
- Zero-downtime releases aligned with your existing DevOps and governance model.
- Shadow environments for high-risk journeys (payments, credit, treasury, KYC).
- Feature-flag based rollout and gradual migration of segments and channels.
- Rollback strategy defined upfront with clear decision points.
- Monitoring, logging and alerting integrated with your NOC/SOC tools.
Design System, Governance & Capability Building
Once the new interface is stable in production, we consolidate a Design System and a governance model that can be owned by your internal teams. The objective is that modernization does not become a one-off project, but a capability your organization can evolve autonomously.
We document components, tokens, usage rules and contribution workflows so that existing squads and new teams can deliver future features without breaking the experience or re-introducing technical debt.
- Design System with tokens, components and patterns (Figma + Storybook).
- Contribution and review model for internal squads and vendors.
- Guidelines for performance, accessibility and security on new features.
- UX optimization cycles based on analytics and qualitative feedback.
- Roadmap for extending modernization to other channels and products.
