You will get Enterprise Microservice Backend — Java Spring Boot
Project details
Need an enterprise microservice backend built by someone who's done it in production? I've delivered high-performance platforms processing millions of events daily with 99.9% uptime.
What you'll get:
— Latest Java 21 + Spring Boot 3.5 technology stack
— Clean layered architecture with reusable shared libraries
— API Gateway with flexible authorization levels (public/authentication/authorization)
— Feign Client for type-safe inter-service communication
— RFC 7807 compliant exception handling
— OpenAPI 3.0 + Swagger UI for API documentation
— Jenkins CI/CD pipeline for multi-module builds
— Production-ready with Docker/Jib containerization
— Kubernetes deployment with Helm charts (dev/staging/prod)
— OpenTelemetry tracing + Prometheus/Grafana monitoring
— Flyway migrations, ArchUnit tests, Spotless formatting, Code quality enforced via SonarLint
— Full source code, Helm charts, CI/CD config, and docs
Production results:
— 10% latency reduction via Redis optimization
— 20% faster queries with Elasticsearch
— 20% performance gain using APM monitoring
CKAD + AWS certified. I build backends that scale under pressure and deploy without downtime. Let's talk!

About Duong
Senior Backend Engineer | Spring Boot Microservices | CKAD Certified
Hanoi, Vietnam - 9:48 am 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.

Steps for completing your project
After purchasing the project, send requirements so Duong can start the project.
Delivery time starts when Duong receives requirements from you.
Duong works on your project following the steps below.
Revisions may occur after the delivery date.
Requirements & Architecture Planning
Review your system requirements, define microservice boundaries, design API contracts, data models, event schemas (Kafka topics), and overall system architecture.
Microservice Development & Integration
Build each microservice (User, Notification, Audit, Event, Business Service) with Spring Boot 3, Redis caching, Elasticsearch, and inter-service Feign clients.
