Software Engineer II @ American Express
Building AI Infrastructure • Distributed Systems • Performance Engineering
I'm a software engineer passionate about understanding how intelligent systems behave under load, fail, recover, and scale.
I enjoy building open-source infrastructure, designing reproducible experiments, and publishing engineering insights around AI systems, distributed systems, caching, and performance engineering.
I believe the best way to learn is by building ambitious projects that solve real engineering problems.
A laboratory for learning distributed systems through reproducible failure experiments.
Instead of simulations, FaultLab uses real services, controlled fault injection, and observability to explain behaviors such as:
- Retry storms
- Cascading failures
- Database latency
- Connection pool starvation
- Timeout propagation
Tech
Python • PostgreSQL • Docker • Prometheus • Grafana • OpenTelemetry
A learned semantic cache eviction policy for LLM applications.
SmartEvict investigates lightweight learned eviction policies for semantic caches using reproducible experiments and real conversational workloads.
