KerjaHub

The Challenge

The job market in Southeast Asia is fragmented, with job seekers struggling to find opportunities that match their skills and experience. Traditional job portals focus on quantity over quality, leading to mismatched hires and high turnover rates.

Employers spend significant time and resources filtering through unqualified applicants, while talented candidates often get lost in the noise.

The Solution

KerjaHub reimagines the hiring process by focusing on skills-based matching rather than traditional keyword-based job searches. We built a platform that:

• Uses AI-powered skill assessment to verify candidate capabilities
• Matches candidates with companies based on culture fit and growth potential
• Provides upskilling recommendations to help candidates become job-ready
• Streamlines the hiring workflow for employers with smart filtering

Technical Approach

As CTO, I led the architecture design and implementation of a scalable, microservices-based platform capable of handling millions of users.

Key Technical Decisions:

• Flutter for Mobile: Single codebase for iOS and Android with native performance
• Golang Backend: High-performance API services handling 10K+ requests/second
• Next.js for Web: SEO-optimized job listings and employer dashboard
• Event-Driven Architecture: Real-time notifications and matching updates

Impact & Results

"KerjaHub has transformed how we hire. The quality of candidates we receive is significantly higher than traditional job boards."

Key Learnings

Building KerjaHub taught me valuable lessons about scaling technology and teams simultaneously. The most important insight was that user experience trumps feature richness — we achieved higher engagement by simplifying the application flow rather than adding more features.
