What I'm looking for

I'm open to remote work and relocation.

At Intetics, I design and build distributed production systems for enterprise customers, taking work from architecture and backend services through frontend and cloud delivery. I built Kafka, RabbitMQ, and AWS SQS workflows with idempotent message processing, retries, and dead-letter queues.

On an analytics and visualization platform, I developed data-intensive dashboards and real-time D3 visualizations. I cut a critical reporting endpoint’s response time by about 75% by restructuring PostgreSQL queries, adding indexes, and caching results in Redis.

At Zangi, I developed production features for a secure cross-platform communication platform, including WebSocket workflows and recurring subscriptions. Earlier, at Evistep, I built full-stack features for task management and tender monitoring platforms. I also mentor junior engineers and use Claude, Cursor, and ChatGPT in day-to-day development.
