Evaluate trade-offs related to scalability, latency, fault tolerance, and cost.
Partner with development teams early to prevent reliability and performance issues before production.
Capacity Planning & Scalability
Assess system readiness for growth scenarios such as:
"We plan to onboard 10,000 users in 6 months - can the system support it?"
Perform capacity and scale analysis for:
Application tiers
Databases
Messaging systems
Kubernetes compute and storage
Provide evidence-based recommendations supported by metrics, benchmarks, and production data.
Engineering Collaboration

Communicate complex technical findings clearly to both engineers and business stakeholders.
Required Technical Skills
Strong understanding of distributed systems and performance engineering
Ability to read, analyze, and troubleshoot Java code
Hands-on experience with:
Kubernetes (resource management, scaling, container behavior)
Linux internals and tuning
PostgreSQL (queries, indexing, performance optimization)
Proven experience building or operating high-availability, high-throughput systems
Strong analytical and problem-solving skills with a data-driven approach
Nice to Have

Messaging systems such as ActiveMQ
