About Ayush Raj

Software Engineer with 3+ years of experience building scalable systems, AI-driven solutions, and full-stack applications. Currently at Cisco, I architect enterprise-grade AI systems that automate complex workflows and deliver real business impact. I specialize in Agentic AI and RAG (Retrieval-Augmented Generation) architectures. I've expanded Cisco's PSIRT security suite, and designed modular LLM frameworks that optimize costs while future-proofing against model obsolescence. My work sits at the intersection of AI, security, and scalable backend systems. → AI/ML: LangChain, LangGraph, RAG, MCP, GPT-4, Llama, Knowledge Graphs (Neo4j), Vector DBs (ChromaDB)→ Backend: Python, Django, FastAPI, PostgreSQL, MongoDB, REST APIs→ Frontend: React, TypeScript, Tailwind CSS→ DevOps: Docker, Kubernetes, Kafka, Ansible, CI/CD, Nginx→ Security: Offensive security, CTF competitions, vulnerability assessment My career at Cisco started as a Technical Intern, where I built dynamic dashboards and optimized data pipelines. As a Software Consulting Engineer, I engineered robust Django backends, designed authentication systems, automated test generation with AI, and built end-to-end chatbot interfaces in React. Today, as SCE II, I lead the development of multi-agent AI architectures. 2x Cisco Security Summit CTF Winner (2024 & 2025) — Exploited complex vulnerabilities across UI, RDP, FTP, SSH, and DDoS vectors APJC AI Innovation Challenge Winner — Built Splunk analytics with closed-loop automation Sustainathon Hackathon Winner — Developed an LLM-powered chatbot for biodiversity research CCNA & DevNet Associate Certified I believe AI should solve real problems, not just demo well. I'm passionate about building LLM systems that actually work in production — not just prototypes that break at scale. I love the challenge of turning complex enterprise requirements into elegant, automated solutions.When I'm not shipping code, you'll find me competing in CTFs, exploring new AI frameworks, or mentoring developers on building agentic systems.' I'm always open to conversations about AI agents, RAG architectures, security, or interesting engineering challenges. Feel free to reach out! ayush@xayush.com xayush.com
