I build production backend systems and developer tools—from service architecture and data flows to testing, observability, CI/CD, and deployment.

Published VS Code extension for multiline inline completions through your existing Codex account. Debounced requests, cancellation of stale work, duplicate suppression and rate limiting control request volume. Bounded context, secret-like filename exclusions and read-only model execution define execution boundaries; local diagnostics expose request, acceptance and latency metrics.

Six local Go MCP servers with 62 tools for Trello, App Store Connect, Google Play, YouTube, Instagram and GoDaddy. Provider-specific OAuth/JWT authentication and separate OAuth setup commands, secret redaction with regression tests, and CGO-disabled standalone binaries released for macOS, Linux and Windows. Concrete safeguards include private-by-default YouTube uploads and domain confirmation before DNS zone replacement.

VPS provisioning and deployment automation with a CLI, REST endpoints and web dashboard. Integrates DigitalOcean instance creation, DNS management, SSH/SFTP, NGINX, Let's Encrypt certificates, provider firewall rules and fail2ban. Deployment workflows cover static sites and Docker Compose applications, connecting server setup, project upload and web-server configuration.

- Go backend systems: service architecture, REST and gRPC APIs, data flows and real-time communication.
- AI & developer tooling: LLM integrations, MCP servers, editor extensions and explicit execution boundaries.
- Delivery & observability: infrastructure automation, tests, CI/CD, deployment, monitoring and incident diagnosis.
Migrated production REST services to gRPC with approximately 10% lower latency, built and supported a real-time chat backend, and automated Telegram notifications for 400+ users.
My work spans architecture, implementation, tests, deployment, monitoring and incident diagnosis.
