Work History
Software Engineer
AWS
Bellevue, WA
08.2025 - Current
- Designed and operated high-throughput, low-latency distributed systems processing millions–billions of events/day using event-driven architecture.
- Built pub/sub and streaming-based pipelines, enabling near real-time data processing and downstream integrations.
- Improved system reliability and availability (e.g., 99.9%+ SLA) by implementing fault-tolerant designs, retries, backpressure handling, and graceful degradation.
- Optimized performance at runtime level (threading, memory usage, async processing), reducing P95/P99 latencies and infrastructure cost.
- Owned end-to-end service lifecycle: design docs → implementation → testing → deployment → production support.
- Enhanced observability via structured logging, distributed tracing, and metrics dashboards (latency, error rates, saturation).
- Led on-call rotations, root-caused critical incidents, and drove postmortems with actionable fixes.
- Partnered with multiple teams to standardize APIs and data contracts across services.
- Ensured security and compliance best practices (authN/authZ, data handling, least privilege access).
- Ran experiments and load tests to validate scaling limits and improve system efficiency.
Software Engineer
Apple
Austin, TX
01.2023 - 07.2025
- Developed and scaled backend services supporting high-availability, user-facing systems with strict latency requirements.
- Built asynchronous processing systems and queue-based architectures, improving throughput and resilience.
- Contributed to design and architecture discussions, ensuring services were horizontally scalable and fault-tolerant.
- Improved service observability and operational excellence, reducing MTTR and increasing uptime.
- Implemented robust deployment strategies (canary releases, rollback mechanisms) to minimize production risk.
- Participated in live-site operations, diagnosing production issues and implementing long-term fixes.
- Collaborated cross-functionally to deliver features aligned with product and infrastructure goals.
- Mentored junior engineers and contributed to code quality through reviews and best practices.
Junior Software Developer
Oracle
Austin, TX
01.2022 - 12.2022
- Built backend services and APIs using Java/Python, focusing on performance and maintainability.
- Developed tools to automate workflows and improve system efficiency, reducing manual overhead.
- Gained experience with distributed systems fundamentals (scalability, consistency, fault tolerance).
- Assisted in debugging production issues and improving system reliability.
- Wrote unit/integration tests and contributed to CI/CD pipelines.
- Collaborated within an agile team, contributing to feature delivery and sprint planning.
