What I'm looking for

I'm looking to build SaaS platforms, backend services, APIs, search solutions, and data-processing systems using PHP, Symfony or Laravel, PostgreSQL, RabbitMQ, OpenSearch, and Docker.

I've built SaaS products and commercial solutions at Resosoft using Symfony and Laravel/Lumen, including REST APIs for mobile applications and administrative panels. I develop data-processing systems with YML feed parsing, RabbitMQ queues, and OpenSearch indexing.

I've delivered intelligent search and recommendation functionality with synonym handling, typo correction, and relevance optimization, while integrating payment providers and third-party services. I also configure CI/CD, deployments, Datadog monitoring, and automated unit, functional, and acceptance tests.

Previously, I developed educational platforms, CRM systems, microservices, Telegram bot functionality, and web applications across PHP, JavaScript, React, Vue.js, PostgreSQL, MySQL, and Docker.
