Upwork

Upwork, the world's leading freelancer marketplace connecting millions of businesses with independent professionals, partnered with YUPL to address critical scaling challenges and implement next-generation features. Our engagement focused on platform performance, AI-powered talent matching, and enhanced security infrastructure.

With over 18 million freelancers and 5 million clients on the platform, even marginal improvements in performance and matching accuracy translate to significant business impact. YUPL's expertise in high-scale systems and machine learning enabled transformative improvements across the platform.

The Challenge

Operating at Upwork's scale presents unique engineering challenges. The platform processes millions of job postings, proposals, and messages daily, whilst maintaining sub-second response times. The matching algorithm must balance multiple factors including skills, experience, availability, and historical performance to connect the right talent with the right opportunities.

• Peak traffic exceeding 50,000 concurrent users
• Complex matching algorithm requiring real-time processing
• Payment processing across 180+ countries
• Fraud detection across diverse transaction patterns
• Search functionality spanning millions of profiles

Our Solution

YUPL deployed a dedicated team of platform engineers and ML specialists who embedded with Upwork's existing teams. We implemented a comprehensive performance optimisation programme that reduced API response times by 40% through database query optimisation, caching strategies, and microservices refactoring.

Our ML team developed an enhanced talent matching model using transformer-based architectures that significantly improved match quality. The new model considers contextual factors like project complexity, communication preferences, and historical success patterns to surface the most suitable candidates.
