Performance Testing & Engineering
Design and execute performance, load, stress, endurance, scalability, spike, and capacity tests.
Validate performance of cloud-native applications running on Kubernetes (K8s).
Build realistic workload models that simulate production-scale traffic and customer usage patterns.
Establish performance baselines and continuously improve system scalability and reliability.
Microservices Performance Analysis
Perform detailed root cause analysis and optimization recommendations for applications leveraging:
Kubernetes-based microservices
Kafka-based event-driven architectures
REST and GraphQL APIs
Redis caching layers
Oracle databases
Elasticsearch clusters
Spark-based batch and streaming workloads
Analyze system behavior across

Kafka & Messaging Performance
Design and execute load testing for Kafka-based service-to-service messaging systems.
Analyze consumer lag, throughput, partition distribution, batching efficiency, and message processing latency.
Tune Kafka producer, broker, and consumer configurations to optimize performance.
Identify bottlenecks and provide recommendations to engineering teams for scalability improvements.
API Performance Engineering
Validate latency, throughput, concurrency, error rates, and service-level objectives (SLOs).
Perform end-to-end performance analysis across distributed API ecosystems.
Identify bottlenecks in service interactions and recommend optimizations.
Spark Performance Optimization
Analyze Spark batch and streaming job performance.
Investigate executor utilization, partitioning strategies, shuffle operations, memory management, and query execution plans.
Recommend performance improvements to reduce execution time and infrastructure costs
Performance Diagnostics & Optimization
Conduct deep-dive investigations into production and pre-production performance issues.
Collaborate with developers to identify root causes and implement fixes.
Review architecture and code changes from a scalability and performance perspective.
Recommend improvements in application design, infrastructure configuration, caching, database queries, and messaging patterns.
