Consultation Services
I help teams design, improve, and troubleshoot production-grade backend systems built with Java, Spring Boot, distributed systems, event-driven architecture, and AWS.
My services are focused on backend engineering problems where architecture, reliability, integration, scalability, and maintainability matter.
Backend Architecture & System Design
I can help review or design backend architectures for new and existing systems, including service boundaries, data ownership, integration patterns, scalability, failure handling, and operational concerns.
- Microservice and modular architecture design
- Service boundaries and domain decomposition
- Distributed system design
- API architecture and integration strategy
- Architecture reviews and modernization planning
Java & Spring Boot Engineering
I provide hands-on engineering support for Java and Spring Boot applications, from implementation to production hardening.
- Spring Boot service development
- REST API design and implementation
- Spring Data JPA and Hibernate
- Database and transaction design
- Security and authentication integration
- Code and architecture reviews
Event-Driven & Distributed Systems
I help teams build reliable asynchronous communication between services, especially where message delivery, retries, idempotency, and failure recovery need to be explicit and supportable.
- Kafka-based messaging
- Transactional outbox and inbox patterns
- Idempotent message processing
- Retry and failure handling strategies
- Event contract and integration design
- Operational visibility for asynchronous workflows
Cloud & AWS Backend Systems
I can help design and improve backend systems running on AWS, with a focus on practical architectures rather than unnecessary infrastructure complexity.
- AWS-based backend architecture
- RDS and PostgreSQL
- Containerized applications
- CI/CD and deployment workflows
- Cloud integrations and managed services
- Production readiness and observability
Production Reliability & Troubleshooting
A significant part of backend engineering happens after deployment. I can help investigate difficult production issues and improve the system so similar problems are easier to diagnose in the future.
- Transaction and concurrency issues
- Database performance and locking problems
- Messaging and integration failures
- Retry and timeout behavior
- Observability and diagnostic improvements
- Production support and root-cause analysis
Technical Modernization
I can also help teams modernize existing Java applications without forcing a full rewrite.
- Legacy Spring application modernization
- Framework and Java version upgrades
- Architecture simplification
- Improving maintainability and testability
- Introducing better observability and failure handling
Open-Source & Library Engineering
I design and maintain the NERV open-source Java ecosystem, which focuses on reusable solutions for backend engineering concerns such as event reliability, auditing, exception handling, and persistence.
This work reflects the same engineering principles I apply to client projects: clear abstractions, predictable behavior, production supportability, and developer-friendly design.

How We Can Work Together
Engagements can range from focused technical reviews to hands-on engineering support.
- Architecture consultation
- Technical design and review
- Hands-on backend development
- Production troubleshooting
- Short-term technical advisory
- Longer-term engineering engagements
Not Sure What You Need?
You don't need to have the solution figured out before reaching out. If you can describe the system, the problem you're facing, and what you're trying to achieve, we can start from there.
