Senior Python backend engineer building production AI/LLM and analytics platforms.
SlovakiaWhat I'm looking for
I’m a Senior Python Backend Engineer with 9 years of professional software engineering experience, including 6+ years in commercial Python backend development. I’m strongest in backend-heavy product engineering: APIs, async processing, data workflows, integrations, permissions, analytics, and business automation.
Recently, I designed and delivered production AI/LLM features for an analytics SaaS platform, including a RAG-based analytics chat, LangGraph workflows, metric insights, and LLM-assisted configuration flows. I also helped design and deliver the first production version of an analytics and AI/LLM platform from scratch—covering backend APIs, async jobs, BigQuery-based analytics, Kafka/Redis processing, and production reliability.
I’ve worked across the full backend lifecycle, from architecture to deployed services. I helped split a legacy Django monolith into production microservices, refactored a legacy ETL codebase into reusable components (reducing typical feature-development time by about 25–30% and bug-fixing time by roughly 2x), and contributed to safe migrations using automated parity testing, alongside technical mentoring and stakeholder communication.
