Hire Refinitiv Developers for LSEG Market Data and Analytics Solutions 

Build financial applications around trusted market, reference, news, and analytics data. Our Refinitiv developers help investment firms, fintech platforms, and enterprise teams integrate current LSEG data services while supporting legacy Refinitiv environments where needed.

Modernize How Your Team Uses Refinitiv and LSEG Data

Refinitiv is now part of LSEG, and many firms are balancing established data workflows with newer LSEG Workspace and platform services. The integration challenge often includes entitlement rules, instrument identifiers, streaming sessions, data normalization, usage controls, latency, and migration from legacy desktop or server applications.

FintegrationFS helps teams turn licensed LSEG data into practical products and workflows. We can build market-data services, research dashboards, portfolio views, screening tools, alerting systems, Excel or web integrations, and data pipelines that connect with internal risk, trading, CRM, and reporting platforms. All implementations are designed around the products and entitlements available to your organization.

Why Work With Us?

Capital-markets data experience

We understand the difference between reference, historical, streaming, pricing, fundamentals, news, ESG, and analytics workflows, and how each affects architecture and user experience.

Entitlement-aware design

We account for user permissions, data licenses, caching restrictions, redistribution rules, and auditability instead of treating licensed financial data like a public API.

Legacy and modern integration support

Our team can maintain established Refinitiv applications while helping you plan a controlled move toward supported LSEG Workspace and data-platform services.

Full-stack delivery

We can handle ingestion, normalization, databases, APIs, dashboards, Excel workflows, alerting, cloud deployment, monitoring, and integration with internal systems.

Frequently Asked Questions

Yes. Refinitiv is part of London Stock Exchange Group, and LSEG has been bringing products and branding under the LSEG name. Many users still search for Refinitiv development because established APIs, data workflows, and internal terminology remain in use.

2. What does a Refinitiv developer do?

A Refinitiv developer integrates licensed market and financial data with applications, dashboards, models, and enterprise systems. The work can include authentication, entitlement handling, streaming, data normalization, analytics, monitoring, and migration.

3. Can you integrate LSEG Workspace with internal systems?

Yes, when the required Workspace capabilities and licenses are available. We can connect internal data, models, alerts, and workflows using supported integration methods.

4. Can you build real-time market-data applications?
