I build software by understanding how it actually executes — CPU time, memory movement, network latency, and failure behavior. My focus is not just application logic, but the full execution path from request entry to data storage and back.
I enjoy working on backend services, distributed systems, and infrastructure where performance, reliability, and observability matter. I prefer measuring real behavior over relying on abstractions.
- Runtime performance and latency reduction
- Memory usage and allocation patterns
- Caching layers and data locality
- Distributed system failure modes
- Concurrency and workload distribution
- Infrastructure-aware application design
- Observability and production debugging
- Throughput vs resource utilization trade-offs
Runtime
- Node.js internals, event loop behavior
- Async I/O and concurrency tuning
- Worker threads and clustering
- V8 profiling and heap analysis
Networking
- HTTP connection lifecycle
- Reverse proxy and load balancing
- Service-to-service communication
- Backpressure and retry strategies
Data
- PostgreSQL query planning and indexing
- Redis caching and eviction policies
- Connection pooling and latency optimization
- Consistency vs performance trade-offs
Infrastructure
- Docker containerization
