Semenykhin.
10+ years building web applications, SaaS platforms, CRM systems and business automation. Backend, frontend and technical leadership in one practice.
From a bottleneck
to a system-level fix.
My work often starts with an existing product: slow queries, a frozen interface, architectural problems or complex integrations. I investigate the cause, change the implementation and check the concrete result.
In multi-tenant systems, I have worked with isolated branch databases, migrations and indexing. For background processing, I have implemented idempotent RabbitMQ jobs and error handling. For delivery, I have built CI/CD with automated testing across multiple platforms.
