Challenges and Solutions

Data Fragmentation Across Siloed Systems

Critical data was spread across siloed systems including PostgreSQL, BigQuery, and Oracle databases, making it impossible to get a unified view of business operations.

Solution

OptiSol architected a centralized Medallion architecture with Bronze, Silver, and Gold layers progressively refining data. This created a single, unified source of truth for analytics across the enterprise.

Legacy System Performance Bottlenecks

The legacy OBI system faced significant performance issues, leading to slow report generation and inability to handle increasing data complexity, delaying critical business decisions.

Solution

OptiSol migrated to Oracle Analytics Cloud consuming optimized data from the Gold layer, reducing report load times by 70% and providing business leaders with timely insights.

Business User Reporting Dependency

Business users were heavily dependent on the data team for custom reports, creating bottlenecks that delayed decisions and prevented autonomy in analytics.

Solution

OptiSol developed interactive dashboards and enabled self-service analytics through OAC training, allowing business teams to create their own analyses from trusted Gold layer data while reducing ad-hoc workload by 40%.

Manual and Error-Prone Deployments

Deployment of updates to the data platform and BI tools was manual, time-consuming, and prone to errors, posing risks to business continuity.

Solution

OptiSol established a robust CI/CD pipeline using Jenkins and Git that automated testing and deployment, reducing deployment time from hours to under 30 minutes while decreasing errors by 95%.

Limited In-House Expertise for Modern Cloud Analytics

The organization lacked specialized expertise in Oracle Analytics Cloud, Medallion architecture patterns, and modern data engineering practices needed for successful platform modernization.

Solution

OptiSol deployed experienced data engineers and OAC specialists through a flexible T&M engagement model, providing hands-on implementation support while upskilling internal teams through knowledge transfer sessions and collaborative development practices.

Extending Enterprise Workforce Management Platform Lifespan with AI-Powered Modernization

A US-based enterprise workforce management organization faced a critical decision regarding their 20+ year-old business-critical employee absence and scheduling platform built on PowerBuilder.

The EQAI system, serving as the operational backbone for managing employee absences, scheduling, and time-off requests across multiple facilities and thousands of users, required modernization to address increasing technical debt, outdated user interfaces, and scalability challenges brought on by frequent acquisitions and growing workforce populations.

Rather than pursuing a risky full replacement, OptiSol deployed a two-phase AI-powered modernization strategy: Phase 1 leveraged PB Studio AI agents to automatically modernize UI/UX while maintaining the PowerBuilder foundation, and Phase 2 introduced PB Shift to gradually migrate the architecture to a modern 3-tier web platform. This intelligent approach reduced modernization effort by 40-60% while extending the platform's viability by over six years and establishing a clear path toward complete architectural transformation.
