Enterprise Event Simulation Platform
A configuration-driven simulation platform for testing distributed systems under realistic conditions such as burst traffic, out-of-order delivery, retries, and partial failures.
Highlights
- Built a scenario-driven simulator to exercise distributed systems before production releases
- Supports burst and steady event generation, routing, transformation, and sinks
- Implements deterministic replay for debugging and regression validation
- Models real failure modes: timeouts, retries, backpressure, drop rates, and partial outages
Links
Impact
- Provides a repeatable testbed for validating system behavior and data correctness
- Enables reproduction of hard-to-debug production failure scenarios using configuration
- Demonstrates strong reliability, testing, and systems-engineering mindset
Context
Distributed systems fail in predictable but hard-to-reproduce ways: out-of-order events, retries, backpressure, partial outages, and timing issues.
This project exists to make those failures deterministic, repeatable, and testable before production.
What This Is
A configuration-driven event simulation platform consisting of:
- A Java-based simulator runtime
- A scenario library for realistic workloads (financial-style events, device fleets, failure tests)
- Environment and behavior configuration profiles
- Deterministic replay for debugging and regression testing
Most scenarios can be created without code changes—only configuration.
Outcomes
- A reusable platform for testing system behavior under stress and failure
- A controlled way to validate data correctness and system resilience
- A practical demonstration of reliability engineering and test infrastructure design
Why This Matters
This is the same philosophy used in mature data platforms and distributed systems:
Don’t wait for production to discover failure modes. Simulate them, reproduce them, and fix them early.
