Enterprise front ends

Where enterprise front ends get hard

The problems large product organizations bring to us, and what we deliver for each.

01

Incremental modernization

An aging front end slows every release, and a full rewrite freeze isn't an option.

We plan staged improvements from jQuery, JSP, Struts UI, plain HTML and JavaScript, Handlebars.js, and ASPX into a maintainable front end, around active business workflows.

Migration plan, sequencing and release checkpoints.
02

Design systems & internationalization

A growing product needs consistent interfaces across teams, releases and regions.

We build shared components, interaction patterns and locale-aware content flows. Pills and BeeWise illustrate our design-system and internationalization work.

Reusable UI foundations with language and locale support.
03

Accessibility audit and remediation

Accessibility gaps create barriers in essential user journeys.

We audit against WCAG 2.2 AA, test keyboard and screen-reader journeys, remediate issues, and support repeatable accessibility testing and documentation.

An issue baseline, prioritized fixes and validation evidence.
04

Performance at scale

Slow loading and rendering make critical product journeys harder to use.

We use Lighthouse, Core Web Vitals, DevTools and bundle analysis to find bottlenecks, then apply lazy loading, image optimisation, code splitting, SSR or SSG, caching and CDN strategies where they fit.

A measured baseline, prioritized fixes and repeatable checks.
05

Secure roles, data & integrations

Different users need secure, clear paths through dense data and connected systems.

We design role-aware workflows, align permissions with backend rules and handle API loading, failure and recovery states. Authentication, browser security controls and dependency checks protect the interface boundaries.

Connected workflows with clear states, access controls and security review evidence.

Typical environments: enterprise applications, operations platforms, customer portals, live dashboards, SaaS platforms and commerce experiences.

In their own words

Master Lab ScientificView project ↗

“Managing operations becomes challenging when you have a distributed team working across different parts of the world. Tranz Technologies took the time to understand our challenges, workflows, and operational needs, and built the right ERP solution for us.

Today, most of our processes are automated with very little manual intervention. Our sales, purchases, enquiries, and other key operations are now tracked and managed through a single platform, making it much easier for our team to work efficiently and maintain complete visibility across the business.

Great work by the Tranz Technologies team.”

“Per-user licence costs had become a major concern for our sales team of more than 30 people. We had already tried several CRM products before Tranz Technologies proposed a custom solution that we could fully own, without ongoing per-user licence fees.

The CRM is now built around our actual sales workflows and gives us the flexibility to add more users as our team grows. Having complete ownership of the platform has been a real advantage for us.”

Common questions

What engineering leaders ask before starting

Practical answers about scope, integration and working together.

How much does it cost to hire a frontend developer?

Cost depends on experience, framework expertise, scope, integrations and engagement length. Senior developers typically cost more when the role includes architecture decisions and independent delivery. Share your requirements and we will recommend a team setup and provide a quote.

How can I hire dedicated frontend developers?

Tell us about your product, stack, team and timeline. We shortlist developers for the work you need, then you meet them and assess the fit. Once selected, we agree on responsibilities, working hours and onboarding so they can start contributing to your codebase.

Do frontend developers handle testing and debugging?

Yes. Our developers test components and key user journeys, check browser compatibility and responsive layouts, and fix issues before release. Automated checks and code reviews help keep existing features stable as your product evolves.

How do you handle our security review?

We support customer security questionnaires and technical reviews. A typical security-review response cycle is 2 weeks, depending on scope and documentation requirements.
