About Manu Mohan

QA Engineer with 7+ years of experience in automation, API validation, infrastructure testing, and VoIP systems—now expanding into LLM-powered test tooling and LangChain-based document QA. Built a Django+LLM tool to generate OpenAPI-compliant payloads from YAML and natural language inputs. Delivered a CLI pipeline to validate rack-level setups using LLDP parsing, VLAN/cabling checks, and Redfish hardware metrics via Ansible. Tools deployed for production-ready rack validation at scale. Created a Flask-based static analyzer for C, C++, and Robot Framework scripts with YAML/regex-based rule engines and deviation reporting. Migrated Robot Framework suites to Pytest, modularizing shared libraries and logic with prompt-assisted conversion. Prototyped LangChain RAG workflows using FAISS and recursive summarization to query test logs, PDFs, and JSON config files. Analyzed ExtremeCloudIQ OpenAPI spec to scope real-world LLM automation for test stub generation and API validation. VoIP testing experience includes SRTP, SIP, TLS, and Proxy Media Mode using SIPp, Wireshark, and XML-driven call flows.
