We trace difficult symptoms through application code, the JVM, JDBC, transactions, and the database.
Finding the cause of latency spikes, long-tail response times, and throughput collapse under load.
Finding hot paths, allocation pressure, retries, contention, and wasted work that drive compute demand.
Diagnosing leaks, retained objects, excessive allocation, long pauses, and collectors that cannot keep pace.
JDBC connection exhaustion, long-running or open transactions, lock waits, slow queries, and database-side resource pressure.
Blocked threads, deadlocks, lock contention, overloaded executors, and shared-resource bottlenecks.
Explaining failures that resist reproduction, cross system boundaries, or disappear during conventional profiling.
Lightweight developer and operations tools built for real software.
AI Badger prepares focused code and Git context locally for any AI chat. Use it from the command line or VS Code without connecting your repository to an AI provider.
Turn Actuator health and metrics into a focused self-hosted dashboard with local history.
Build lightweight ETL and data migration workflows using SQL, XML, Java, and scripting languages without a heavyweight data platform.
PVR Labs is a boutique software lab focused on Java performance, systems engineering, and practical developer tools. Founded and led by Ted Kupolov, PVR Labs draws on engineering experience at Google, Apple, and ServiceNow, including work with large-scale production Java and database systems.
That production engineering experience underpins PVR Labs’ work in JVM performance and troubleshooting. Ted is also the creator of Scriptella ETL, and continues hands-on product development through AI Badger and StatLite.
