Hire Integration Engineer — Proven Case Studies

Client: Fintech company, Series C B2B payment provider

Challenge: The client needed to Hire Integration Engineer experts because their legacy transaction routing system was failing. Processing time exceeded 8 seconds per request, causing a 14% drop in checkout conversions.

Solution: Smartbrain.io deployed a dedicated team of 3 senior Integration developers for a 6-month engagement. The engineers utilized Apache Kafka and MuleSoft to rebuild the core middleware, connecting the payment gateway directly to SAP S/4HANA.

Results: The augmented team delivered the new architecture in 12 weeks. The optimized API layer achieved a 65% latency reduction, dropping processing times to under 3 seconds, and increased successful transaction throughput by 2.1x.

Client: Healthtech provider, mid-market telemedicine platform

Challenge: To scale their virtual clinic, the CTO had to Hire Integration Engineer specialists to connect their proprietary app with hospital Epic systems. A 4-month hiring backlog for HL7/FHIR experts stalled the product roadmap.

Solution: Smartbrain.io provided 2 vetted Integration engineers within 48 hours. The team spent 4 months building secure, HIPAA-compliant REST APIs using Node.js and AWS API Gateway to sync patient records bidirectionally.

Results: The integration was successfully deployed in 16 weeks. The automated data sync eliminated manual entry, saving hospital staff 200+ hours monthly and reducing patient onboarding time by 40%.
