About the company

Fintech
USA

Finsemble provides a developer-focused library designed to accelerate the creation of native Windows desktop applications in the fintech space. The framework enables seamless server-client interaction, cross-platform support, and NuGet-based integration to simplify financial software development.

The engagement

Time to hire: 12 days on average
Core team: 2 Full-Stack developers, 1 QA, 1 BA, 1 PM
Duration: 6 months
Budget: NDA
Tech stack: .NET Core, .NET Framework, Node.js, WebSockets, NuGet, C#, Visual Studio

Project Overview

Finsemble partnered with Intelvision to build a scalable development library that simplifies fintech desktop application development. With Intelvision’s Talent as a Service model, they quickly assembled a dedicated team that delivered WebSocket-powered real-time updates, a NuGet-compatible package, and a developer-friendly interface—accelerating time-to-market and streamlining internal development workflows.

Challenges and Pains

Framework Fragmentation
Finsemble needed a framework that could support both .NET Core and .NET Framework for broad platform compatibility. Balancing dual-framework support led to complexity in development and delayed feature delivery.
Real-Time Communication Gap
Achieving seamless real-time data exchange between desktop applications and backend systems was a critical requirement. Existing approaches lacked efficiency, resulting in performance issues and limited interactivity for end users.
Talent Shortage for Niche Stack
The company faced difficulty sourcing developers with deep knowledge of both desktop app architecture and modern WebSocket protocols. This niche skill gap slowed down development cycles and affected roadmap execution.

Solution

Intelvision delivered a tailored Talent as a Service solution to address Finsemble’s technical and staffing challenges:

Specialized Engineering Team
A core team consisting of 2 Full-stack developers, with PM and BA support, was assembled and onboarded in just 12 days to accelerate development.
Scalable Architecture
Our engineers built a robust library that supports both .NET Core and .NET Framework, allowing for wider compatibility and long-term scalability across fintech use cases.
Real-Time Integration
By implementing WebSocket communication between the Node.js server and the desktop application, we enabled real-time data syncing, significantly improving performance and UX.
Developer Enablement
The library was packaged for NuGet to streamline adoption and integration, while an intuitive interface made it easy for financial teams to build apps quickly and reliably.
