Realtime Interface Engineering
Root-caused a 1GB memory leak on a live trading platform — incorrect useEffect dependency causing cascading re-renders on every WebSocket tick.

Building frontend systems. Debugging where they break.
I build and debug performance-critical, real-time frontend systems. My work lives where state, rendering, and correctness collide — trading platforms, healthcare products, and long-running UIs that fail in non-obvious ways.
I write about frontend engineering the way it actually behaves in production — not the way tutorials describe it.

Memory Reduction
1GB → 400MB on a live trading platform
Bundle Size Cut
Sentry SDK from 400KB to 70KB gzipped
Users Migrated
Zero-downtime geo-based platform migration
Traders Served
Position analytics with real-time market data
Root-caused a 1GB memory leak on a live trading platform — incorrect useEffect dependency causing cascading re-renders on every WebSocket tick.
Restructured Sentry SDK initialization and tree-shook wildcard imports to cut monitoring bundle from 400KB to 70KB — an 82% reduction.
Led geo-based routing and compliance gating for 500K+ existing users and 600K+ new sign-ups across jurisdictions — zero downtime migration.

Garbage Sentry data led us to multiple SDK bundles and wildcard imports. Fixing the init pattern and tree-shaking cut our Sentry payload from 400KB to 70KB.

A production debugging story — how I tracked down a 1GB memory leak on a crypto trading platform caused by a subtle useEffect dependency and unmemoized table re
The kinds of production problems I spend most of my time solving — real incidents, not hypotheticals.
Traced a 1GB heap bloat on a trading page to an incorrect useEffect dependency causing cascading re-renders on every market tick. Reduced to 400MB.
Sentry SDK was loading 400KB gzipped due to wildcard imports and late initialization. Restructured to tree-shakeable named imports — 70KB, error tracking from first paint.
Options analytics page crashing for 15% of users. Root cause: unbounded state growth in chart re-renders under sustained market data updates.
Built a design system using Amazon Style Dictionary with custom transforms, adopted 100% across React Native and web teams, cutting design-to-code drift by 60%.
I optimize for depth in a few areas rather than shallow familiarity across many tools.
Frontend systems are long-running, stateful machines — not just collections of components.
Most serious UI failures I've debugged were not visual issues. They emerged from performance regressions, unstable references, or incorrect assumptions about state and timing.
These problems often surface as broken UX, even though the root cause lives deep in rendering behavior, data flow, or lifecycle management.
