Hi 👋 I'm Shikha Pandey

Software Engineer II @ American Express
Building AI Infrastructure • Distributed Systems • Performance Engineering

Portfolio • LinkedIn • Medium

About

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.

🚀 Current Work

FaultLab (Currently Building)

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

🧠 SmartEvict

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.
