Case Studies
- Kubernetes ConfigOps: Migrated configuration from centralized database to Kubernetes ConfigMaps, resolving concurrency bottlenecks and eliminating single points of failure.
- .NET GraphQL Optimization: Optimized GraphQL resolvers in .NET Framework, reducing load on core banking infrastructure by 20% through elimination of redundant downstream requests.
- Legacy Migration Strategy: Migrated User Accounts and Transaction APIs to latest .NET versions for security compliance and performance improvements.
- Data Export Optimization: Increased CSV download throughput from 300 to 30,000 units by decoupling document processing from client requests.
- Pipeline Architecture: Replaced on-the-fly XML-to-CSV conversion with preprocessed data and SOLR-based document storage.
- .NET/SOLR Integration: Automated backend processing of incoming documents with SOLR indexing for efficient retrieval.
- MongoDB Sharding: Analyzed and optimized MongoDB sharded indexes across multi-region deployments handling terabytes of security data.
- Latency Reduction: Reduced dashboard rendering time by 40% for critical security event screens, directly improving the incident response time for global customers.
- Critical Infrastructure Support: Mitigated production outages (e.g., Japanese region reporting failure) via rollback strategies and root cause analysis using OpsGenie.
- Microservices Decomposition: Re-architected a legacy PHP speech therapy system (Novotalk) into a high-performance Node.js environment.
- Concurrency Scaling: Scaled system capacity to handle 3x more concurrent requests while processing data 40% faster.
- Async Event Architecture: Implemented Redis for caching high-frequency objects and RabbitMQ to decouple client request loads from database writes, ensuring zero data loss during traffic spikes.
- .NET Core Migration: Led the migration of high-scale CRM business management software from full .NET Framework to .NET Core 5/6, future-proofing the application lifecycle.
- Java & Legacy Support: Maintained and upgraded legacy Java-based backend systems alongside the .NET migration, ensuring business continuity for enterprise clients.
- Real-Time Collaboration Architecture: Architected a WebRTC-based communication tool from scratch, consolidated with ReactJS web components for real-time user interaction.
- Credit Union API Integration: Integrated WordPress auto dealer theme with Credit Union SOAP API for automated credit scoring and financing approval.
- Logistics CRM System: Built MERN stack CRM for moving company with order management, dispatch tracking, and route optimization for delivery trucks.
- Legacy Modernization: Migrated clients from PHP monoliths and legacy third-party dependencies to modern MERN stack.
