About

Professional summary

I am a technical support professional with experience resolving software issues for customers, internal teams, and enterprise stakeholders. My background combines hands-on application troubleshooting, issue triage, defect reproduction, testing, and technical communication.

I began my career as a Technical Support Engineer and progressed to Lead Technical Support Engineer. I also helped establish a technical support function, supporting customer technical needs and enterprise HCM and payroll applications.

More recently, I have worked across SaaS applications, cloud systems, integrations, data issues, and software delivery initiatives. I partner with users, developers, business teams, and engineering teams to investigate problems, verify fixes, and improve product workflows.

My technical experience includes SQL, MySQL, REST APIs, Jira, functional testing, integration testing, AWS, Azure, Salesforce, Python, and technical documentation. I am comfortable translating user feedback and business requirements into actionable technical improvements.

I have held senior business analysis, technical program, product, QA, and support-oriented roles with organizations including Disney, Tata Consultancy Services, Wells Fargo, Autodesk, and BreakFree Productions. I work effectively with distributed teams and customer-facing software environments.
