Job Success
Chernivtsi, Ukraine - 8:02 am local time
Most clients come to me when:
• integrations are unreliable or breaking
• data is out of sync between systems
• APIs are already connected, but something “feels off” or they need a clear plan before scaling
That’s where I focus - reviewing existing integrations, identifying issues, and turning them into stable, predictable systems.
🔧 What I do:
• API Integration (REST, Webhooks, third-party APIs)
• Integration Review & Audit (identify issues, bottlenecks, risks)
• Troubleshooting & Debugging broken integrations
• Data Sync & Workflow Automation
• Integration Architecture (clean, scalable system design)
Typical scenarios I work with:
• Stripe, Google APIs, OpenAI, CRM integrations
• SaaS platforms with multiple connected services
• Systems with partial or messy integrations
• Products preparing to scale and needing reliability
