@ayoolaroy
I build reliable backend systems, APIs, integrations, and automation for AI, insurance, fintech, and blockchain products.
What I'm looking for
I'm a backend engineer with seven years of experience building systems from small applications to large-scale production platforms.
At Notch.ai, I build and maintain integration layers for an AI customer support agent, connecting Zendesk, Intercom, Kustomer, and internal tools. I've improved agent behavior, automation, response paths, and escalation logic, helping raise response accuracy to roughly 75–80%.
At TrustBlock, I led backend architecture and Security Data API development, improving average response times by around 35–40% through query optimization, caching, and request validation. I also reviewed smart-contract protocol logic and edge cases for clients including Alchemix.
I've led backend work that supported Casava's Series A funding, expanded insurance coverage to more than 300,000 entrepreneurs, reduced AWS costs at Digital Abundance, and built systems used by banks, insurers, healthcare clients, and blockchain products.
