Assylzhan Nyussupov.
Senior backend engineer. I build distributed systems in Go, and lately the infrastructure that keeps AI agents useful and honest.
- Six-plus years of production Go; five of Temporal, AWS, and Terraform. Currently at Shopware, on the core team behind Nexus, the event-driven integration platform, GA since May 2026.
- Designed and shipped the Temporal-based workflow engine that executes every Nexus integration, first commit to GA cutover in three months.
- Before that at Wildberries: owned an order-management core serving ~1.5K RPS at peak across four Kubernetes clusters, and shipped an LLM debugging agent into the team's chat.
Selected work
go-agent-reliability
Dependency-free Go reliability primitives for long-running agent processes: idle watchdog, stuck detection, atomic checkpoints, crash classification with resume-context synthesis. Agents fail differently from ordinary services; this is the library I kept rewriting until I extracted it.
mcp-oauth-go
Turns an HTTP MCP handler in Go into an OAuth 2.1 resource server per the MCP authorization spec: RFC 9728 protected-resource metadata, RFC 8707 audience validation, JWT verification, per-tool scopes, audit logging.
