SDKs & containerized systems on AWS — now leading AI / RAG work.
From license-enforcement and tamper detection at Dell to an AI-enabled marketplace today. Ask the agent anything about my work — it runs on a Go backend that retrieves from my real résumé and GitHub.
Hi — I'm Neeraj's portfolio agent. I answer from his real résumé, GitHub and LinkedIn using retrieval + tools, all served by a Go backend. Ask me anything, or tap a question below.
About
I'm a senior backend engineer with over a decade building production systems that hold up under real load — distributed services, SDKs, and the infrastructure around them.
My work tends to sit where backend depth meets reliability and security: at Dell I built core parts of an internal license-enforcement service, including usage metering and tamper detection backed by encryption and cryptographic hashing, and ported a performance-critical C component to a single pure-Go artifact. More recently I've gone deep on AI integration — OpenAI, retrieval-augmented generation, and tool-based (MCP-style) agent workflows.
Today I lead a small team delivering an AI-enabled consumer marketplace, owning architecture and technical direction end to end. I care about the team as much as the code: setting standards, mentoring, and turning vague requirements into shipped systems.
