Profile: https://flows.cv/hatruong

- Transform Real time Data Platform from Terabytes to Petabytes to Exabytes.

- Build Next Gen Real time ingestion, Sub second Query at high concurrency Hybrid transaction/analytical processing (HTAP) data platform at Exabytes scale.

- Continuous cost optimization (tracking records saving Millions/Year)

- Build fully automated CI/CD systems using many AWS services (e.g Cloudfront, ELB/ALB, ECS, Lambda, Kinesis, Firehose, ElasticCache, ElasticSearch, RDS, DynamoDB...) with 0 downtime upgrade, 0 down time scale up/down, auto scaling. 

- Build high scale performance frame work that can generate hundreds of thousands events per sec at the data volume of 10Gbps+ for many data types with hundreds of fields to qualify both data ingestion and all data analytics use cases for Big data platform.

- Strong experience in networking (L2-L7 protocols, analysis/troubleshooting/performance tools).

- Strong experience in smartphone management and security (more focus on iOS and Android).

- Strong experience in trouble shooting, tuning performance issues on complex system (network devices, load balancer (f5, apache, haproxy), java applications, databases).

- Strong experience in configuring f5, apache, haproxy.

- Strong experience in design performance automation framework and implementation.

- Experience in working with multiple processes (CMM, Agile, TMap).
