What I'm looking for

I'm looking to build reliable, scalable systems, contribute to architecture and technical direction, lead development work, and solve complex engineering challenges with international teams and clients.

At IT Aces, I develop and evolve highload platforms for the CIS market alongside a US SaaS website builder and marketing platform. I build core backend and frontend components, contribute to architecture, and work directly with US clients on requirements and technical discussions.

I designed and implemented a workflow engine for business-process automation, including DSL-based configuration, state machines, transitions, conditions, role-based execution, and external API integrations.

Earlier, at the National Nuclear Center of the Republic of Kazakhstan, I developed and maintained internal web applications and information systems, improving the performance and reliability of enterprise solutions across PHP, Laravel, databases, and server administration.
