The Zero-Downtime Cloud Transformation
Migrating 1M requests/sec without dropping a single packet.
Executed a high-stakes lift-and-shift for a mission-critical fintech ecosystem. By treating infrastructure as software, we achieved what was considered impossible: a complete platform migration with zero maintenance windows.
Key Technical Wins
- Migrated high-traffic applications serving 100,000 to 1 million requests per second
- Built Python automation to discover legacy application details and store in BigQuery
- Implemented Redis, PostgreSQL, and Cassandra replication using Ansible
- Migrated Kafka from on-prem to Confluent Cloud with live replication
- Created comprehensive migration templates and runbooks
- Led team of 4-7 engineers through complex migration phases
Major Projects
High-Frequency Trading Infrastructure
Crypto · Cryptocurrency
Engineered and deployed 100% of the production infrastructure for a high-volume crypto trading platform on AWS using Terraform (IaC). This robust architecture, featuring ECS, AWS CodeDeploy, and comprehensive CloudWatch alerting, ensured 99.99% uptime and supported thousands of concurrent trades.
- Engineered IaC using Terraform from scratch, reducing provisioning time.
- Set up CI/CD with AWS CodeDeploy for ECS, accelerating deployment frequency.
- Implemented CloudWatch alerting and monitoring, improving system uptime by 12%.
- Led and managed team of 10 across geographies, boosting project velocity.
Zero-Trust Fintech Architecture
Letsbloom · Financial Services
Engineered a resilient, scalable Azure Kubernetes Service (AKS) infrastructure for a critical fintech platform using IaC principles. Streamlined security practices by deploying HashiCorp Vault for zero-trust secrets access, and reduced security validation cycle time by 40% through a new automated testing suite.
- Eliminated credential exposure risk by 90% through automated Vault injection on AKS..
- Developed a comprehensive Python automation test suite.
- Optimized scalable Azure cloud infrastructure resulting in a 10% reduction in cloud expenditure.
- Automated and optimized the CI/CD pipeline using Azure DevOps accelerating deployment.
Velocity at Scale: 200 Deploys/Day
Bukalapak · E-commerce
