Senior Software Engineer · SRE & DevOps experience Building dependable AI-agent infrastructure — from data access and routing to human-in-the-loop delivery.

Ho Chi Minh City, Vietnam · Software engineer since 2018

I build systems at the boundary where AI agents meet production systems. My work spans structured data access, LLM gateways and context economics, developer tooling, and delivery systems that keep humans in control.

I value dependable interfaces, explicit trade-offs, and evidence over hype — whether the result is guardrailed database access, a bounded agent loop, or a tested pull request.

• Agent infrastructure — MCP servers, tool execution, context engineering, and durable sessions.
• Reliable and economical AI — routing, fallbacks, budgets, observability, and useful cost controls.
• Software delivery — automation that produces reviewable, testable changes without hiding the failure modes.

I contribute to selected open-source infrastructure through the @FreePeak organization and to selected upstream projects. The first two projects below are my newest DSH plugins.

Keep coding-CLI conversations inside the DeepSeek Harness GUI. dsh-mux adds a Mux panel, slash commands, a host tool, and a remote service for resumable conversations. Claude Code is enabled today; the plugin also discovers OMP, Pi, Cursor, Agy, and Command Code adapters, which remain disabled until each has a tested answer parser, while opencode is reported missing until its binary is available. Each turn runs one process and resumes by the CLI’s session id, without requiring a live bidirectional PTY.

A policy layer for bounded, reviewable agent runs. dsh-feature-loop uses the DeepSeek Harness extension points for step ceilings, cheap-first routing, deterministic stall detection, and pre-dispatch human approval. Its standalone runner exercises the same policies with explicit cost and step budgets. The plugin is hosted on the harness rather than maintaining a vendored fork, keeping the control plane explicit and the failure path fail-closed.
