Olayeni Williams
@olayeniwilliams
Client-focused Account Manager and Scrum Master-certified leader improving retention, satisfaction, and measurable client growth.
What I'm looking for
I’m a client-focused Account Manager with experience managing customer relationships, onboarding, case management, and stakeholder engagement across UK-based organisations. I’m Scrum Master-certified, and I consistently turn data and communication into improved outcomes for both clients and delivery teams.
I boost customer satisfaction by 20% through faster complaint resolution, proactive communication, and stronger engagement strategies. In account roles, I grow service package sales by 15% using personalised, needs-based recommendations, while also reducing transaction and billing errors by 30% through improved payment-handling protocols and meticulous record keeping.
As a primary point of contact, I lead structured onboarding and regular check-ins, interpreting KPIs and communicating results clearly to stakeholders. I coordinate with internal delivery teams to keep milestones and timelines on track, maintaining a 90%+ on-time delivery rate and 100% accurate client records.
Beyond account management, I’ve supported agile delivery as a Junior Scrum Master/Business Analyst—facilitating 20+ sprint ceremonies, translating requirements into user stories, and maintaining full project documentation. I’ve also strengthened service fundamentals through high-volume customer support and flexible classroom teaching, building trust quickly in fast-moving environments.
