I am a Software Engineer with 6+ years of experience designing scalable systems and architectures, currently specializing in AI automation and workflow engineering. My background as a Senior iOS Engineer has provided a strong foundation in system design, API integration, modular architecture, and cross-team collaboration, which I now apply to automation and AI-driven solutions. In recent projects, I have designed and implemented end-to-end automation architectures using Make, n8n, OpenAI, webhooks, APIs, and SaaS integrations. These systems automated processes such as document classification, lead qualification, email workflows, content publishing, monitoring, and knowledge management. My approach focuses on building transparent, modular, and maintainable workflows that can be easily understood and operated by internal teams.…I am a Software Engineer with 6+ years of experience designing scalable systems and architectures, currently specializing in AI automation and workflow engineering.
