>About

Senior Android Developer with over 9 years of commercial experience — from POS terminal payment systems and enterprise MRM solutions to consumer apps and games.

I'm fascinated by the intersection of mobile development and AI. I actively use AI tools (Claude Code, n8n, LLM APIs) in my daily workflow.

I love automating and organizing — I have several Telegram bots for personal databases: calendar, recipes, shopping.

I'm writing a life simulation: cells, rules, emergent behavior — it's fascinating how simple algorithms give rise to complex systems.

Outside of code, I play guitar, jaw harp, and hang drum, write poetry, and travel. I climbed Elbrus, did mountaineering, rock climbing, and flew a paraglider. Curious about space, philosophy, and psychology. Learning English (B1) and Spanish (A2) — I want to visit Peru.
