Altuğ CEYLAN

Senior backend engineer from Antalya, Turkey, with 5+ years of building data pipelines, distributed systems and multi-tenant platforms. I now build Apify Actors that are reliable, cheap to run, and give you clean data you can use straight away.

Background

• 🗄️ Led an Elasticsearch → ClickHouse migration that cut infrastructure costs by up to 90%
• 🔄 Designed and maintained distributed backend services and ETL pipelines that processed high-volume data from external sources such as Google Search Console and Google Analytics, supporting a multi-tenant platform used by 1000+ teams.
• 🛡️ Added monitoring, structured logging and automated recovery that cut operational incidents by ~40%
• 🤖 Author of clickhousemcp , an open-source MCP server that lets AI agents query ClickHouse in plain English (12,000+ downloads)

What my Actors focus on

• Change monitoring: get only what changed (prices, reviews, rankings, new listings), not the same rows every run
• Reliability: high run success rates, and a clear error item instead of a silent failure
• Fair pricing: pay per event, tuned to keep your costs low

My Actors

• GetYourGuide Price & Review Monitor: price changes, sell-outs, new reviews and new competitors for tour operators

Stack: TypeScript, Node.js, Python, Crawlee, ClickHouse, Elasticsearch, RabbitMQ, Docker, MCP / LLM integrations
