Staff Software Engineer · Frontend Platform & Architecture · AI/Agent-enabled Systems · Developer Experience
I'm a Staff Software Engineer (Frontend Platform) at Walmart Global Tech with 12+ years of experience building the infrastructure layer that powers other engineers' work.
I lead architecture and technical strategy for a platform powering 1200+ applications and enabling 3500+ developers across a large-scale distributed engineering org. I've driven the evolution from library-based abstractions to AI/agent-driven models — introducing MCP (Model Context Protocol), AST codemods, and agent-based migration tools that reshape how teams interact with the platform.
Beyond code, I care deeply about engineering culture: architecture RFCs, design documents, mentoring engineers, and building platforms future teammates are grateful to inherit.

"The best engineers I know spend more time thinking than typing. Good code is a side effect of clear thinking."
- Platform thinking over feature thinking — Build the layer that accelerates other teams
- Simplicity over cleverness — Readable code ages better than clever code
- Document decisions, not just implementations — ADRs and RFCs matter
- Build for your future teammates — They haven't joined yet
- Performance is a feature — Not an afterthought
- 💼 Staff / Principal Engineer roles — Frontend Platform, Developer Experience, AI Tooling
