Memory Leak Visualization and Go (Golang) Migration

May 2023 – Jul 2023

Log Visualization Dashboard

Objective

Enable faster detection of memory leaks by making fatal log patterns visually obvious.

Approach

• Built a web-based log visualization dashboard using Plotly Dash with structured charts and log views

• Designed intuitive visual layouts to help engineers quickly identify spikes, clusters, and anomalies

• Enabled systematic tracking of memory-leak signatures and long-term trends across large log datasets

Impact

• Deployed a production-ready dashboard that significantly reduced debugging time

• Improved ongoing memory-leak monitoring and trend analysis

Python → Go (Golang) Migration

Objective

Improve diagnostic performance by migrating critical tooling from Python to Go.

Approach

• Migrated 1,600+ lines of Embedded Event Manager (EEM) scripts from Python to Go (Golang)

• Ensured byte-for-byte output parity between legacy and new implementations to guarantee correctness

• Optimized performance-critical hot paths during migration

Impact

• Achieved approximately 5× faster execution compared to Python-based diagnostics

• Improved reliability using Go's compiled execution and static typing

Overall Impact

• Performance: ~5× runtime improvement for diagnostic workflows

• Visibility: Faster and more reliable memory-leak detection through visual log analysis

• Reliability: Reduced runtime errors and improved tooling robustness

Key Learnings

• Language choice matters — compiled languages like Go unlock major performance gains

• Visualization accelerates insight, revealing patterns hidden in raw logs

• Systematic validation is essential when migrating production tooling

• Well-scoped intern projects can deliver real, production-grade impact
