High Availability And Scalability Solution | Various

This section highlights my contributions to designing, deploying, and optimizing high availability and scalability solutions for a wide range of customers across different industries and countries.

These projects focused on maintaining business continuity, ensuring data availability, and meeting Recovery Time Objective (RTO) and Recovery Point Objective (RPO) standards across diverse environments. The tools and strategies employed ranged from native #SQLServer solutions to custom architectures involving cloud and open-source technologies.

Anonymous Managed Service Provider | Canada

This Managed Service Provider (MSP) supported multiple global clients, each with unique business continuity requirements. I collaborated with the client’s remote teams to understand workload distribution, downtime tolerance, and recovery expectations. Based on individual needs, I implemented different high availability configurations including #AvailabilityGroup, #Replication, and #FailoverCluster. All deployments were tested for RTO and RPO compliance and fine-tuned to handle client-specific scenarios.

Anonymous HR Software | Singapore

This client needed a baseline evaluation of their #SQLServer environment before implementing a high availability strategy. After performing a health check and identifying bottlenecks, I configured Transactional #Replication to serve reporting needs and offload read queries. The setup was tested rigorously to ensure it aligned with the customer’s RTO and RPO benchmarks.

In this project, the client requested bi-directional synchronization between an #Azure SQL Database and six on-premise databases. I proposed and successfully implemented Merge #Replication, enabling seamless data flow in both directions while preserving data integrity. Post-deployment, I validated the setup against RTO and RPO metrics to ensure resilience.

Anonymous BPO/KPO | US

This customer operated under tight budget constraints and used #SQLServer Standard Edition, which limited native high availability features. I designed and implemented a basic #AvailabilityGroup that suited their licensing restrictions while meeting their uptime requirements. I validated performance, failover, and recovery procedures to align with defined business objectives.

Anonymous Marketing Startup | Australia

The client needed bi-directional data synchronization between #SQLServer and #MongoDB—a combination not natively supported by commercial tools. I designed a lightweight Python-based custom integration layer to manage real-time sync between the two systems. This solution was tested and confirmed to meet RTO and RPO expectations while maintaining consistency across heterogeneous data platforms.
