About

Software engineer building AI agent systems and the infrastructure under them. I work on Volty at Voltade, a multi-tenant agent platform that answers customers for businesses on WhatsApp and email, and I write agent runtimes in Rust on the side. I usually end up taking a system apart one layer deeper than the job needs.

Experience

Jun 2026 — Present

Software Engineer at Voltade Pte. Ltd.

One of two core engineers on Volty, a multi-tenant AI agent platform. Built the quality layer under its model routing, which scores inference hosts, probes them with evals and moves traffic off bad ones. Designed agent tools (MCP servers with OAuth, PDF, web fetch behind an SSRF guard), made realtime delivery tenant-isolated, and wrote most of the operator app.
