Senior Software Engineer at BIZOO DEV who cut e-commerce search latency from 5,000ms to 200ms across 500M+ records.
AlbaniaWhat I'm looking for
At BIZOO DEV, I built an e-commerce platform from scratch using Laravel, Vue/Nuxt, Swift apps, MySQL sharding, and OpenSearch. It handles 500M+ database records, and I reduced search latency from 5,000ms to 200ms.
I also developed a CRM for 2,000+ users, migrating it from legacy CakePHP to Laravel and reducing order processing time by 80%. For another platform, I integrated OpenAI and Anthropic APIs to automate 90% of inventory management, content enrichment, and translations.
Earlier, at LUXE RECRUTEMENT, I built a recruitment platform core with a PHP backend and Go microservices. At ITMO University, NCCR, I developed real-time research data processing systems and co-authored two patents.
