About Me
</h2>
<p>

With six years of web development experience, I've led projects, conducted developer interviews, and successfully guided a team to build a website in six months, achieving 20,000 Daily Active Users (D.A.U.). I enhanced website performance by increasing loading speed by 50%, halving the bundled file size, and reducing costs by 25%. Additionally, I converted an old PHP/Blade project to React, integrating 80% test cases.

Currently seeking a front-end / back-end / full-stack role. Let talk more about details via email or Linkedin. Looking forward to hearing from you.
