At X5 Group Digital, I build Python services powering 6M daily surveys and 700K daily voice-bot calls. I cut survey latency by 3x, increased call conversion by 20%, and reduced speech-to-text costs by 3x by moving to in-house STT.
I've redesigned monoliths into independently scalable microservices, owned new-service architecture through production, and mentored developers at fintech startup System Solutions. I work across Python, Django, FastAPI, Kafka, PostgreSQL, Kubernetes, and AI-assisted development.
