What I'm looking for

I'm open to EU-remote backend roles where I can build high-load, distributed PHP/Symfony systems and improve product quality, operational efficiency, search, integrations, and revenue.

I'm building high-load classifieds and e-commerce capabilities at Doska for 100K monthly active users, improving Elasticsearch search accuracy by 14% with OpenAI-powered listing keywords and increasing completed deals through trust-focused integrations.

Across OnMoon, SmartOrange, and Svyaznoy, I've delivered revenue-critical backend systems, marketplace integrations that contributed to 50% revenue growth, and automation products that reduced hiring costs by 30%. I build scalable PHP/Symfony services, microservices, search, and integrations for distributed, high-throughput products.
