Viacheslav Zhabonos

I've built and maintained backend services at Yellow Stone since 2021, working across PHP, Yii2, and Node.js on internal and product projects. I designed a domain-infrastructure service and integrated Cloudflare API to automate domain-related operations. On a high-load Node.js project, I implemented database-query caching that reduced constant CPU load from approximately 20–25% to 5–10% and remains stable in production. I also contribute to module and API design, Docker image creation, GitLab CI configuration, and an early Yii2-to-Symfony migration. Previously at FieldPulse, I maintained the backend API for a field service management SaaS product and refactored its QuickBooks integration. Across DIGOPS, TERNALA, Wetelo, and freelance projects, I've delivered PHP applications, APIs, CRM functionality, payment integrations, e-commerce systems, and real estate platform backend logic. I focus on practical, stable, and maintainable solutions, with hands-on experience optimizing SQL, databases, caching, integrations, legacy code, and production performance.
