Kineiro LLC · Kazakhstan

B2B SaaS platform for AI content automation and cross-platform publishing.

• Designed and led the platform from scratch; grew the engineering team from 2 to 10, owned technical direction, and worked directly with sales and client success.
• Built a custom workflow engine (first on Deno, then rebuilt on NestJS): content jobs run as DAGs - topological sort, parallel levels - with a Postgres step cache that resumes from the last completed step and a cross-process job-claim lock for idempotency.
• Orchestrated 20 models across text, image, video and audio with automatic failover; shipped ~1,200 idempotent publications/day to 8 social channels.
• Event-driven architecture on RabbitMQ (guaranteed delivery, dead-letter queues, exponential backoff, graceful degradation); unified MongoDB + SQL data layer with end-to-end observability.

Blockchain wallet ecosystem (international).

• Designed a new microservice backend with a read-through cache in front of all node reads: cut direct node requests ~60% and p95 balance reads from ~600ms to ~150ms (4× faster).
• Extended a Cosmos SDK (Go) chain with 2 custom modules: an on-chain exchange and conversion of the native token into AI-usage tokens.
• Led a team of 3; introduced code review and CI/CD, cutting the release cycle from ~2 weeks to ~3 days.
• Integrated an in-wallet AI assistant for common operations, removing ~30% of routine support requests.
