Technology Transformation

The Modernization Imperative

Legacy technology is the single biggest barrier to AI adoption and digital transformation. Organizations spend an estimated 70-80% of their IT budgets maintaining aging systems — money that could be invested in innovation. These legacy systems create data silos, slow down development, increase security risks, and make it nearly impossible to implement modern AI capabilities.

Shailka Systems has modernized 400+ legacy estates, from mainframe-era COBOL applications to monolithic Java systems, transforming them into modern, API-driven, cloud-native platforms that enable AI and digital innovation.

Our Technology Transformation Services

Legacy System Modernization

We take a pragmatic, risk-managed approach to modernization:

• Application Portfolio Rationalization — Our AI-powered assessment tool analyzes your entire application portfolio — scanning source code, infrastructure dependencies, data flows, API contracts, and usage patterns — to recommend the optimal modernization strategy for each application. This typically identifies 20-30% of applications that can be retired immediately, saving millions in maintenance costs.
• Strangler Fig Migration — For business-critical systems that can't afford downtime, we use the strangler fig pattern to incrementally replace legacy components with modern services, ensuring uninterrupted business operations throughout the migration.
• Mainframe Modernization — COBOL-to-Java/Python migration, mainframe workload rehosting, and data extraction from legacy databases (IMS, VSAM, DB2) to modern cloud data platforms.
• Monolith Decomposition — Breaking monolithic applications into microservices using domain-driven design, event sourcing, and CQRS patterns that enable independent deployment and scaling.

Enterprise Architecture

We help organizations design technology architectures that scale:

• Target Architecture Design — Future-state architecture blueprints that align technology investments with business strategy, defining standards for application development, data management, integration, and infrastructure.
• Architecture Governance — Architecture review boards, technology radar programs, and decision frameworks that ensure consistency and prevent technology sprawl.
• Reference Architectures — Industry-specific reference architectures for common patterns like customer 360, supply chain digitization, and omnichannel commerce.
• Technology Debt Reduction — Systematic identification and remediation of technical debt with prioritized roadmaps that balance debt reduction with feature development.

ERP & Core System Transformation

We modernize the backbone of enterprise operations:

• SAP S/4HANA Migration — End-to-end S/4HANA migration including business process redesign, data migration, custom code remediation, and change management. We've completed 50+ SAP transformation programs.
• Cloud ERP Implementation — Oracle Cloud, Workday, and other cloud ERP deployments with best-practice configurations, integration design, and organizational change management.
• Core Banking Transformation — Modernizing core banking platforms to support real-time processing, open banking APIs, and AI-powered decision making.
• Custom Application Replacement — Replacing bespoke legacy applications with modern alternatives — SaaS solutions where appropriate, custom-built platforms where differentiation is required.

Integration & Middleware

Modern enterprises need their systems to talk to each other seamlessly:

• API Strategy & Management — Designing API ecosystems that enable internal integration, partner connectivity, and developer ecosystem growth with proper governance, versioning, and lifecycle management.
• Event-Driven Architecture — Apache Kafka and cloud-native event streaming platforms that enable real-time data flow between systems, replacing batch-oriented integration patterns.
• iPaaS Implementation — Integration platform (MuleSoft, Boomi, Azure Integration Services) deployment with pre-built connectors, data mapping, and orchestration logic for common enterprise integration patterns.
• Legacy Integration — Connecting modern systems with legacy applications through API wrappers, message queues, and change data capture, enabling gradual modernization without big-bang replacement.

Technology Due Diligence

For M&A scenarios and strategic investments:

• Technical Assessment — Deep evaluation of target company technology stack, architecture quality, technical debt, security posture, and scalability for M&A due diligence.
• Integration Planning — Post-merger technology integration roadmaps that consolidate duplicate systems, unify data platforms, and realize synergies while minimizing business disruption.
• IP Evaluation — Assessment of proprietary technology, algorithms, and data assets for valuation and competitive differentiation analysis.

Digital Workplace

We modernize how employees work:

• Modern Intranet & Collaboration — SharePoint, Teams, and Confluence-based digital workplaces with AI-powered search, knowledge management, and employee self-service.
• Process Automation — Power Platform, ServiceNow, and custom RPA solutions that automate repetitive processes across HR, finance, procurement, and operations.
• AI-Powered Productivity — Enterprise deployment of AI assistants (Copilot, custom GPTs) that help employees find information, draft documents, analyze data, and automate workflows.
