From monolith to team autonomy.

Modernization does not start with choosing a framework. It starts by finding where the architecture is slowing product, engineering, and the business.

Conceptual comparison between a legacy frontend architecture and a modular system

Blocked releases

One team cannot deploy without depending on another.

Tightly coupled frontend

Every channel change requires backend work.

Inconsistent UI

Each team recreates components and patterns in its own way.

Slow onboarding

New developers take months to gain context and autonomy.

Architecture built to change.

Incremental interventions designed to reduce risk while your teams keep shipping product.

Layers of a modular frontend architecture

Microfrontends, without the big bang.

We decompose the monolith module by module with Module Federation. Each team gains deployment autonomy without rewriting everything from scratch.

Client-reported projects averaged 67% less release time.

Visual system of components, tokens, and design system states

Design Systems teams actually use.

Documented components, tokens, Storybook, and clear patterns that speed up onboarding and eliminate UI rework.

Client-reported projects eliminated 41% of UI rework.

Audit & Roadmap

A complete codebase assessment and a roadmap prioritized by business impact.

The roadmap prioritizes measurable improvements across the first 90 days.

Headless Architecture

Separate frontend, backend, and content to launch experiences across every channel.

Client-reported projects averaged 3.2× more team autonomy.

Question 1 of 10

A “yes” indicates a constraint. Your score updates as you move through the diagnostic.

Do releases regularly wait on another team?

Senior frontend architecture, not generalist delivery.

Senfront is based in Lisbon and works remotely with client teams. Every engagement is led by senior frontend architects experienced in large-scale systems.

Questions before you modernize.

Specific answers to the objections that usually block a frontend modernization decision.

Will modernization require us to stop everything?+

No. Senfront works incrementally around the live product. We identify a narrow first boundary, modernize it alongside current delivery, and expand only after the new approach is proven.

How soon will we see results?+

The 45-minute diagnostic produces an initial view of the highest-cost constraints. If there is a fit, the roadmap is structured around observable improvements within the first 90 days, depending on scope and access.

What is Headless Architecture, and do we need it?+

Headless Architecture separates the customer-facing frontend from backend and content systems. It is useful when teams need to publish across multiple channels or change experiences without coordinating every release with backend work. We only recommend it when the business case supports it.

Can our internal teams maintain it afterward?+

Yes. Documentation, pair reviews, training, and knowledge transfer are part of the engagement from day one. The objective is internal autonomy, not long-term dependence on Senfront.

Do you work with React, Vue, Angular, or Next.js?+

Yes. The target architecture is chosen around the existing codebase, team skills, deployment model, and business constraints. We do not impose a framework before diagnosing the system.

How is pricing structured?+

Pricing depends on scope, system complexity, and the level of implementation support required. The initial diagnostic is free; any paid engagement is proposed afterward with clear deliverables and boundaries.

Is the team based in Portugal?+

Yes. Senfront is based in Lisbon and works remotely with client teams. Engagements are led by senior frontend architects.

Luminous modular paths emerging from a legacy architecture

What is the current frontend costing your business?

In a 45-minute session, Senfront identifies the first blockers and delivers a tailored initial assessment—free, with no obligation to continue.

A concrete diagnostic guarantee.

If the 45-minute diagnostic does not identify at least one measurable time or cost-saving opportunity, we provide a second session at no cost.
