Nana Abekah

Senior Software Engineer · March 2025—Present

• Lower AI costs, more resolved inquiries. Architected and led a rewrite of Ada’s AI decision-making engine that lowered inference costs and improved automated resolution in evaluation. Built the initial implementation, then led the engineering team through delivery. Currently rolling out in production.
• Faster, more predictable business workflows. Rebuilt how AI agents carry out multi-step customer-service processes, moving fixed steps into code to avoid unnecessary model calls. Led architecture and hands-on development, then a cross-functional team through launch, including the customer editor and production monitoring.
• Reusable workflows instead of duplicated logic. Built and owned a feature that lets businesses define common steps once and reuse them across customer-service processes. Took it end to end from hackathon prototype to production launch.
• Fewer unnecessary handoffs to people. Designed and shipped a change to when the AI agent escalates a conversation, improving independent resolution and reducing handoffs in controlled evaluation. The results informed a new customer-configurable setting.
• Better answers from less context. Built a system that turns long help-center articles into reusable, source-grounded answers, avoiding the need to process full articles for simple, repeated questions. Improved answer quality in evaluation through search and linked-source retrieval. Currently rolling out in production.
• Shorter waits and more resilient AI services. Removed a concurrency bottleneck that forced model requests to run one at a time, improving response times in an evaluation service. Added AI-provider failover to keep services operating through provider disruptions and resolved complex production customer issues.
• Safer content editing and growing backend capacity. Built safeguards against conflicting simultaneous edits to protect data integrity, improved backend handling of large datasets, and contributed to security incident response.
