Start Legacy Modernization

Legacy System Modernization Service with Elite C# Talent Leverage Smartbrain’s vetted C# augmentation teams to de-risk modernization. Average hiring time: 48 hrs. • Hire in 48 hrs • 2-step senior vetting • Cancel or scale anytime

Why outstaff instead of direct hiring?
Outstaffing gives you instant access to senior C# developers who have already modernized banking cores, logistics ERPs, and healthcare records. You avoid the 6-month recruitment cycle, payroll tax, and retention risks while still keeping full technical control. Our engineers plug into your processes within 24-48 hrs, use your Jira, follow your branching strategy, and report to your leads. Scale up or down at the pace of your backlog, pay only for the hours delivered, and preserve capital for product innovation, not head-count overhead.

CTO

BlueWave Logistics

HIPAA deadlines loomed until Smartbrain’s vetted C# engineers refactored our legacy WinForms EMR into .NET 6 and Docker. Onboarding took one day; productivity matched staff in a week. We cut defect leakage by 40 % and met audit dates comfortably.

Michael Nguyen

Director of Engineering

MedCore Solutions

Our monolithic payment engine on .NET Framework 4.0 throttled growth. Smartbrain placed two C# micro-service specialists who decomposed critical services and implemented gRPC. TPS improved by 55 % while infra costs dropped 22 %.

Industries We Transform with C# Modernization

Banking & FinTech

Legacy System Modernization Service developers in banking replace COBOL cores with scalable C# micro-services, integrate real-time fraud engines, and enable PSD2/APAC open-banking APIs. C# augmentation slashes compliance backlog, drives faster transaction processing, and shields sensitive data with robust .NET security libraries.

Healthcare & MedTech

Regulated hospitals lean on augmented C# teams to modernize HL7 interfaces, migrate WinForms EMR to .NET 6, and add FHIR micro-services. The Legacy System Modernization Service approach ensures HIPAA-ready code, automated test suites, and reduced downtime during clinical hours.

Logistics & SCM

Freight operators modernize aging AS400 TMS by outstaffing C# experts skilled in domain-driven design. They break monoliths into containerized services, optimize route algorithms, and integrate IoT telemetry, making Legacy System Modernization Service essential for on-time deliveries.

Manufacturing

MES platforms stuck on legacy OPC servers migrate to .NET Core with help from Legacy System Modernization Service staff. Outstaffed C# developers implement RESTful APIs, predictive-maintenance analytics, and edge computing that raises OEE across diverse plant floors.

Retail & eCommerce

C# augmentation pushes legacy storefronts off classic ASP to headless .NET 6 back-ends, enabling omnichannel checkout, real-time inventory, and loyalty micro-services. The Legacy System Modernization Service delivers faster page loads and higher conversion rates.

Energy & Utilities

SCADA systems reliant on outdated C and VB6 gain modern dashboards when outstaffed C# engineers refactor to .NET, integrate time-series databases, and add secure MQTT gateways. Legacy System Modernization Service improves reliability and regulatory reporting.

Insurance

Policy-admin platforms migrate from mainframe to Azure Functions via Legacy System Modernization Service. Augmented C# teams craft event-driven architectures, automate underwriting rules, and cut claim-cycle times, boosting customer satisfaction.

Public Sector

Agencies modernize legacy procurement portals with C# augmentation, moving from WebForms to Blazor, bolstering accessibility, and meeting FedRAMP. Legacy System Modernization Service minimizes taxpayer costs while elevating service quality.

Media & Entertainment

Streaming providers replace Silverlight players, adopt .NET MAUI apps, and scale content pipelines using Legacy System Modernization Service. Outstaffed C# developers introduce serverless transcoders and CDN edge optimizations, cutting buffering by 35 %.

Legacy System Modernization Service Case Studies

Client Type: Mid-size FinTech gateway.

Challenge: Their monolithic .NET Framework 4.0 payment core caused latency spikes and compliance exposure—an urgent Legacy System Modernization Service need.

Solution: A Smartbrain-built augmented squad of four senior C# architects decomposed the monolith into ten gRPC micro-services, introduced automated PCI DSS scans, and containerized workloads for Kubernetes. Daily stand-ups stayed with the client’s Scrum Master; knowledge transfer completed in week one.

Result: 55 % lower average transaction latency, 22 % cloud cost reduction, and zero compliance findings in the next audit.

Client Type: Multi-hospital network.

Challenge: A legacy WinForms EMR lacked interoperability, slowing care coordination—critical Legacy System Modernization Service scope.

Solution: Two Smartbrain C# seniors and one QA automated HL7 conversions, rebuilt UI in .NET 6, and added FHIR APIs. They shadowed clinicians to map workflows and executed phased rollouts to avoid downtime.

Result: Chart retrieval time dropped by 38 %, clinician data-entry errors fell 45 %, and HITRUST certification passed on first attempt.

Client Type: Global automotive parts producer.

Challenge: Plant MES on outdated Oracle Forms limited scalability—prompting a Legacy System Modernization Service initiative.

Solution: Smartbrain supplied five C# cloud-rewrite experts who ported core logic to .NET Core micro-services, integrated Kafka for shop-floor events, and deployed to Azure Kubernetes Service. A dedicated DevSecOps handled IaC pipelines.

Result: Production downtime shrank by 31 %, OEE rose by 12 %, and new plants can be onboarded in 2 weeks instead of 3 months.
