Description

<h2>Callstack — Performance-Driven Website Overhaul</h2>

<p>

Project BackgroundCallstack, a 150+ team React Native consultancy serving giants like Meta, Amazon, and Evernote, faced a critical credibility problem. Despite being industry leaders with $30M+ annual revenue and millions of developers using their open-source tools, their website scored only 34 on Lighthouse with a devastating 78% bounce rate. Their digital presence wasn't reflecting their world-class technical expertise.

</p>

<br>

<p>

Challenge FacedThe key challenges included performance that contradicted their reputation (34 Lighthouse score), limited search visibility (only 1 in 5 target keywords in top 10), outdated jQuery-based tech stack, unstructured CMS causing content management nightmares, and an aggressive 6-week deadline due to upcoming business opportunities.

<p>2️⃣ Week 2-3: Performance-Driven Design - Component-based wireframes and beautiful interfaces using Relume for speed while maintaining content-first strategy through Figma prototypes.</p>

<p>3️⃣ Week 4-5: Development Excellence - Built 208 reusable Webflow components, organized 1,256 CMS items across 22 collections, implemented cutting-edge performance optimizations.</p>

<p>4️⃣ Week 6: Launch & Optimization - Comprehensive testing, performance tuning, and team training for seamless scaling.</p>
