Hire Ballerina Developer — Proven Case Studies

Client: Fintech company, Series C payment processor

Challenge: The client needed to Hire Ballerina Developer experts because their legacy API gateway struggled with concurrency, and processing time exceeded 4.5 seconds per transaction during peak loads.

Solution: Smartbrain.io augmented their engineering department with a dedicated team of 3 senior Ballerina developers for a 6-month engagement. The team utilized Ballerina Swan Lake to rewrite the core orchestration layer, implementing native circuit breakers and gRPC microservices.

Results: The augmented team delivered the new gateway in 12 weeks. The optimized architecture achieved a 78% latency reduction, dropping transaction time to 950 milliseconds, and increased concurrent connection capacity by 3.5x.

Client: Logistics provider, mid-market freight forwarder
