Business & Technical Analyst
I turn ambiguous business and technical requirements into clear specifications, data models, and shipped software — bridging stakeholders, analysts, and engineers across compliance-critical platforms.
About
Business & Technical Analyst with proven ability to translate business and technical requirements into system specifications that drive solution design and delivery. Experienced across the full delivery lifecycle — requirements elicitation, data-flow and integration mapping, system-impact assessment, solution design, and functional, non-functional, and security testing. I've helped architect and deliver a production, multi-system web platform end-to-end — from public marketing and lead capture through dashboards, CRM, and finance/admin back office — across operational and compliance-critical environments.
