What I'm looking for

I'm looking to build scalable backend and distributed systems while deepening my work in AI security, agentic security, and systems engineering.

At Zapigo, I build distributed Golang microservices for long-running asynchronous workloads, improving API throughput by 25% and reducing backend CPU usage by 28%.

I created a slot-based RSVP system with automated waitlisting and ticket release, improving allocation efficiency by 34%. I also built Redis-backed workers that reduced pass-generation latency by 65%.

I develop AI agent workflows using LLMs, RAG, LangGraph, embeddings, vector databases, and tool calling to retrieve context and invoke backend APIs. I also built an OCR payment-verification pipeline that reduced manual reconciliation effort by 70%.

Previously at SigTuple, I improved application performance and load times, built state-machine microservices, and worked across Go, Python, React, Linux, and PowerShell. I’m growing my focus in AI security, agentic security, and systems engineering.
