Backend Developer with a track record in high-responsibility corporate environments — combining solid backend work (Python, Java) with frontend capabilities (React) and infrastructure management. I bring the operational rigor of years in corporate IT together with modern product development: clean code, scalable architecture, and production systems — from API integrations to critical system maintenance.
Looking to join a backend team where I can contribute software, AI, infrastructure, and real business experience.
- Distributed & Event-Driven Systems: Real-time ingestion pipelines with MQTT, WebSockets, InfluxDB, and microservices.
- Agentic AI & Developer Tooling: MCP servers, LLM integrations, and IDE extensions for AI-assisted development workflows.
