01About

Frontend platform work.

Hi, I’m Utkarsh.

Frontend engineer with 4+ years of experience in React, Vue 3, and TypeScript, specializing in frontend platform work — design systems, performance, code-quality automation, security hardening, and LLM-powered developer tooling. Shipped tooling adopted across 35+ repositories and 32 applications, and remediated 15+ critical vulnerabilities for HIPAA compliance. Mentors engineers as a primary frontend code reviewer.

Currently at HighLevel, where I run organization-wide frontend quality gates and build Copy-Guard, an AST plus large-language-model validation pipeline.
