Summary

With 10 years of experience in software development, I specialize in building production-ready platforms using нужен доступ к резюме , React, Supabase, and LLM workflows. I have designed and extended low-code frameworks, optimized database schemas, and implemented advanced AI orchestration for scalable applications. Experienced in prompt integration, context persistence, and multi-step reasoning, I deliver robust, traceable, and high-performance software solutions in iterative startup environments.
