## What I'm looking for

```text
I'm looking for Senior Software Engineer or Full-Stack Engineer roles involving complex web products and performance-sensitive systems, with opportunities to work with Rust alongside TypeScript. I'm open to remote work and worldwide relocation with employer-supported visa assistance.
```

## About

```text
At Podscribe, I build and scale a B2B AdTech analytics platform processing 20B+ ad impressions across 67K+ campaigns. I reduced dashboard load time from 4.8s to 1.4s with virtualized 50K+ row tables and optimized real-time chart rendering for 50M+ daily data points.

I own features from architecture and API collaboration through testing and production delivery, using TypeScript, React, Next.js, Node.js, NestJS, PostgreSQL, REST APIs, and WebSockets. I focus on pragmatic architecture, measurable performance, accessible design systems, and software that stays maintainable as teams grow.

At R7, I built renderer-critical capabilities for an enterprise document and presentation editor used by 1M+ people, including a PowerPoint Morph-compatible slide engine. I also reduced rendering time for large presentations by about 34%, cut deployments from three hours to 25 minutes, and owned the macOS native layer.

Earlier, I delivered payment-reconciliation workflows processing 10M+ daily transactions at iFellow and web products for UCHi.RU's EdTech platform. I'm looking for senior software or full-stack engineering work on complex, performance-sensitive web products, particularly where I can use Rust alongside TypeScript.
