I bridge the gap between complex business requirements and scalable technical reality. My approach to engineering is a structured workflow designed to ensure every technical decision drives business value. Strategic Analysis: I translate business goals into technical roadmaps, defining clear KPIs and data requirements for future analytics. Architectural Design: I architect high-load microservices using FastAPI, PostgreSQL, and Kafka, focusing on fault tolerance and scalability. AI Orchestration: I specialize in automating business processes by integrating ReAct agents and RAG systems into existing infrastructures. Ecosystem Integration: I have extensive experience connecting AI with CRM systems (amoCRM), fintech tools (Kaspi QR), and social platforms (WhatsApp, Instagram). I deliver production-ready systems that reduce operational overhead, whether leading teams under Kanban or designing B2B/Enterprise architectures from scratch.…I bridge the gap between complex business requirements and scalable technical reality.
