You will get Java Backend Architecture Review
Project details
I review your Java / Spring Boot application to identify issues affecting stability, performance, and scalability.
This includes code structure, dependencies, configuration, and deployment setup — focusing on real problems that impact production systems, not just theory.
You’ll receive a clear report with key findings and prioritized recommendations, so you know what to fix now and what can wait.
This is a low-risk starting point before refactoring, scaling, or modernization.

About Zulfiqar
Backend Engineer | Java | Spring Boot | Microservices | AWS | Kafka
Lahore, Pakistan - 2:04 am local time
I help companies build scalable Java Spring Boot microservices and fix slow or unstable production systems. With 10+ years of experience, I’ve built backend systems for healthcare analytics and payment platforms where uptime, data integrity, and security are critical.
Whether you’re building a new product or scaling an existing system, I can help you design a backend that performs reliably under real-world load and grows with your business.
🔷 What I can help you with
• Build backend systems from scratch (Java, Spring Boot)
• Design and implement microservices architecture
• Fix production issues impacting users or business
• Optimize performance, latency, and database queries
• Build secure APIs (JWT, OAuth2, SAML)
• Real-time systems (Kafka, WebSockets)
• AWS deployment with Docker & CI/CD
🔷 Where I add value
• Building systems that need to scale reliably from day one
• Fixing performance issues or slow APIs under load
• Resolving production problems affecting users
• Evolving architecture without breaking existing systems
• Designing and integrating distributed systems
🔷 Experience highlights
• Built and scaled backend systems in healthcare and payment domains
• Worked on systems where uptime, security, and data integrity are critical
• Migrated monolithic systems to microservices architectures
• Developed real-time processing pipelines using Kafka
• Resolved production issues and improved system performance
🔷 Tech stack
Java, Spring Boot, REST APIs
Microservices, Kafka, WebSockets
Spring Security, JWT, OAuth2, SAML
PostgreSQL, MySQL, SQL Server
Docker, AWS, CI/CD
🔷 How I work
I start by understanding your system, constraints, and risks — especially in production environments.
You get clear communication, practical solutions, and a focus on building or improving systems without disrupting stability.
🔷 Summary
If you need a backend that is reliable, scalable, and production-ready — I can help design, build, or improve it.
