You will get High Availability Database: MariaDB/MySQL + MaxScale + Redis Cluster
Project details
Database downtime means lost revenue. I'll build a production-ready high availability database and caching cluster that auto-recovers from failures with zero data loss.
Two database HA options to fit your needs:
Option A — MariaDB Master-Slave + MaxScale:
— 1 master + N slaves with binary log replication
— MaxScale proxy for automatic read/write splitting
— Auto-failover: master dies, slave promotes automatically
— Best for read-heavy workloads and simple HA
Option B — MariaDB Galera Cluster (Multi-Master):
— 3+ node synchronous replication, all nodes read/write
— Zero data loss on node failure
— Best for write-heavy workloads and strict consistency
Both options include:
— Redis Cluster or Sentinel for distributed caching
— Automated backup with point-in-time recovery
— Prometheus + Grafana monitoring for DB and cache metrics
— Connection pooling and query optimization
— Full documentation, runbook, and architecture diagram
Production results:
— 99.9% database uptime with auto-failover under 30 seconds
— 10x read throughput improvement with Redis caching layer
Let's make your data layer bulletproof.

About Duong
Senior Backend Engineer | Spring Boot Microservices | CKAD Certified
Hanoi, Vietnam - 8:38 pm local time
With 4+ years as a Backend Engineer & Technical Lead, I specialize in Java Spring Boot microservices for mission-critical systems. My core focus is Intelligent Transportation Systems (ITS), including real-time traffic monitoring, adaptive signal control, and Origin-Destination (OD) matrix analysis — systems that must run 24/7 with zero tolerance for downtime.
What I bring to your project:
- Backend: Java Spring Boot · Microservices · Apache Kafka · Redis · Elasticsearch · PostgreSQL · REST API
- DevOps & Cloud: Kubernetes (CKAD Certified) · Docker · AWS (Cloud Practitioner Certified) · Jenkins · Ansible · Prometheus · Grafana · CI/CD
Key results from production systems:
- Reduced system latency by 10% through Redis caching optimization
- Improved query response speed by 20% with Elasticsearch integration
- Enhanced application performance by 30% using ELK + APM monitoring
- Processed millions of events/day using Apache Kafka and NiFi pipelines
- Led a team of 5 engineers for 2+ years delivering ITS solutions
I also mentor engineers at Viettel Digital Talent 2025 & 2026 in backend architecture and software development best practices.

Discovery & architecture plan
Review your infrastructure, workload patterns, and requirements. Deliver an architecture document with recommended HA topology, server sizing, and network layout for your approval.
Deploy database HA cluster
Install and configure MariaDB cluster (Master-Slave + MaxScale or Galera multi-master). Set up replication, auto-failover, read/write splitting, and connection pooling.
