Software Engineer | Runtime Infrastructure & System Reliability 

I specialize in identifying root causes before they become production incidents. Whether reducing production p99 latency from 400ms to 80ms at Rockwell Automation or building Aegis-a Firecracker/KVM runtime for secure AI-agent execution. I focus on the "gritty" spaces where code meets the kernel.

My approach treats reliability as a primary product requirement. I’ve spent my time profiling CPU hot paths with pprof, tuning PostgreSQL execution plans to eliminate 504 errors during 5,000-user traffic spikes, and hardening microVMs against fork-bombs and lateral escapes.

Core Tech: Go, C++, Java, KVM/Firecracker, Kafka, gRPC, PostgreSQL, Kubernetes, AWS.

## Work Experience
### Software Engineer @ Associated Students, San Francisco State University
Jan 2022 – Present | San Francisco, CA
Tech Stack: C#, Python, PostgreSQL, Azure Functions, REST APIs, Docker
•Automated transactional data synchronization between campus point-of-sale and payroll systems using C# Azure Functions, eliminating a 10-hour/week manual CSV reconciliation process prone to human entry errors
•Isolated thread contention during a 5,000-user enrollment spike via jstack; tuned pool logic to eliminate 504 errors that previously blocked ~15% of students
•Established a SemVer-based versioning strategy for internal REST APIs serving 4 campus departments, eliminating 'dependency hell' where uncoordinated schema changes previously stalled weekly deployments
•Identified a nested loop join on an unindexed 2M-row audit table that was timing out reporting dashboards; implemented partial GIN indexes to support JSONB search, reducing p95 latency by 30%
•Caught silent data inconsistencies caused by missing transaction boundaries in Azure Function executions, adding explicit commit and rollback handling to eliminate stale-read failures across enrollment cycles

### Software Engineer Co-op @ Rockwell Automation
Jan 2024 – Jan 2025 | San Francisco Bay Area
Tech Stack: Go, C++, PostgreSQL, gRPC, REST, Docker, Linux
•Engineered Go and C++ telemetry ingestion services for industrial PLCs; maintained consistent 600 RPS throughput during burst device-sync windows across distributed nodes
•Investigated burst-load latency incidents using pprof, trace data, and runtime profiling, isolating CPU hot paths and request-path bottlenecks that reduced p99 latency from ~400 ms to ~80 ms
•Profiled PostgreSQL query plans on a 10M-row time-series table where missing composite indexes caused dashboard timeouts; redesigned schema to use partitioned tables, cutting p95 read latency by 35%
•Caught a silent API contract violation during integration review, where an undocumented field removal in a gRPC response would have broken downstream compatibility before release
•Traced a serialization bottleneck in gRPC response encoding under burst traffic, replacing reflection-based marshaling with pre-generated protobuf code and cutting per-request allocation overhead by ~40%

### Software Engineer Intern @ BLUE SQUARES CONSULTANCY LTD
Jan 2020 – Jan 2021
Tech Stack: Java, Python, Kafka, PostgreSQL, Linux
• Improved consumer throughput by ~40% by adding partition-aware routing (consistent hashing) after noticing uneven partition utilization and hot-spotting in a Kafka consumer group
• Worked on Kafka offset monitoring and safer commit behavior during rebalances; learned the failure modes around ordering and duplicate processing in distributed consumers
• Built data validation checks to catch schema drift/type violations before downstream reporting pipelines
• Wrote Python utilities to automate ETL workflows into PostgreSQL for reporting
