We replace your front-end layer with a modern, component-driven architecture (React, Angular, or Vue) while keeping your backend, core logic, APIs, and data fully intact. No disruptions, no replatforming, and no backend rewrites.

No. Onera operates strictly on the presentation layer. Your backend remains untouched — we consume your existing REST, SOAP, GraphQL, or event-based endpoints through a decoupled integration layer with caching, interceptors, and adapters to ensure stability and performance.

Yes. We implement microfrontend-compatible designs and progressive rollout strategies — module-by-module, without requiring a big-bang release. This is ideal for large teams or regulated environments.

Absolutely. We work with banking cores, ERPs, insurance engines, government stacks, and proprietary monoliths. Our adapter layer normalizes responses, handles edge cases, and isolates the new front-end from backend inconsistencies.

We implement OWASP front-end security practices, CSP hardening, secure routing, and role-based interfaces. For regulated industries, we also implement audit logs, traceability, governance rules, and encrypted environment variables.

Yes. We offer maintenance programs: monitoring, UX optimization cycles, analytics-based improvements, and continuous updates aligned with your product and engineering roadmap.

Yes. Every modernization includes a scalable Design System built with Figma + Storybook + tokenization (CSS variables, theme tokens, accessibility rules). Your internal teams receive full documentation, governance guidelines, reusable components, and long-term UI consistency.

We use Jest, Cypress, Playwright, Testing Library, and contract testing integrated into CI/CD pipelines with coverage thresholds, accessibility audits, and performance validations (Core Web Vitals).

Yes. Onera maintains a portfolio of pre-built mobile applications for multiple industries (delivery, booking, POS, healthcare, eCommerce, logistics). These apps can be customized, branded, extended, or integrated with your backend as part of your digital modernization or product strategy.

We follow a co-creation model: aligned ceremonies, technical documentation, shared Git workflows, and transparent sprints. Architecture decisions are made collaboratively, and your internal engineering teams maintain full visibility.

No downtime. Deployments are done in parallel in shadow mode. New interfaces are activated gradually through feature flags or progressive exposure to user roles.

Pricing depends on the number of modules, views, integrations, UX complexity, and API readiness. We provide a detailed technical quotation with scope, milestones, timelines, and team composition based on your platform’s reality.
