3D Pros supports Capco on a financial trading platform combining live market data, specialist workflows, and operationally important code quality.

Fast-changing data, complex interface states, and ambiguity across frontend, backend, and QA made consistent delivery harder.

Senior React and TypeScript delivery, GraphQL and Apollo integration, rendering optimization, SonarQube-led refactoring, and repository-aware MCP agents for engineering and QA.

Clearer refinements, more consistent reviews, less avoidable rework, and stronger collaboration across engineering and quality workflows.

3D Pros partnered with Profeko on financial modeling and citizen-facing applications for Polish gminas, connecting complex workflows with secure government services.

The interfaces needed to remain usable while meeting accessibility, authentication, legal, and public-sector delivery requirements.

React, TypeScript, Vite, and Ag-Grid interfaces integrated with C# APIs and gov.pl authentication, supported by WCAG practices and GitHub Actions releases.

Production platforms with verified-citizen login, reusable financial interfaces, inclusive access, and a more structured release lifecycle.

3D Pros supported Hemmersbach as distributed teams depended on heavily used internal React applications handling more than 150,000 production requests each day.

Legacy workflows needed to become faster and easier to evolve without compromising stability or stakeholder confidence.

React, Redux Toolkit, and TypeScript delivery backed by automated tests, CI/CD, Figma prototypes, code review, and hands-on team enablement.

150k+ daily requests supported, approximately 30% workflow-efficiency improvement, six or more validated prototypes, and three or more engineers onboarded or mentored.
