Sadek builds custom software, API integrations, and production systems for enterprise clients at Devpro. He works across the stack from frontend interfaces to backend services and cloud infrastructure. On client work he often owns the glue between CRMs, telephony, and internal tools: reliable connectors, validation, and the operational details that keep automations running after handoff. He cares about clean interfaces, testable integrations, and shipping systems operators can trust day to day.
