At Magma Ads, I grew from developer to lead engineer, taking responsibility for the architecture and backend of core ad-tech and e-commerce products. I developed an ad platform with an ad server, creative editor, and CDN, as well as analytics for traffic and ad performance.
I also developed Google Ads synchronization to automate campaign management and a shopping aggregator with product feed imports and Elasticsearch catalog search. I’ve worked across Laravel and MySQL as well as newer TypeScript, React, and PostgreSQL services, and built internal tools in Rust.
On my solo project Палітурка, I designed, built, and run a Ukrainian book price aggregator for finding the cheapest multi-store basket, including delivery. It combines feed ingestion and polite crawling, exact basket optimization, and LLM features with evals, cost caps, and fallbacks; I also use an agent harness and AI checks in its development workflow.
