    Performance & architecture

I’m Gautam — a Senior React Native Engineer who ships production-grade mobile and web experiences and optimizes them for real-world constraints: flaky networks, large codebases, and millions of active users.

I’ve contributed to high-scale apps (including a Super App with 5M+ active users), led end-to-end feature delivery, and worked on performance optimization, state management, and offline-first flows. I also enjoy AI-assisted development and practical LLM integrations that improve developer velocity without sacrificing quality.

Currently building

AI tooling for developers (PR review automation), performance playbooks for React Native, and reusable component patterns for scalable app teams.
