What I'm looking for

I'm looking to build secure, scalable backend platforms and AI-agent integrations, owning delivery from design through production while improving reliability, performance, and developer velocity.

At Loyalty Methods, I deliver Java and Spring Boot middleware for BP and 7-Eleven, taking services from design specifications through production support. I build secure REST APIs, React workflows, and AWS deployments for retail operations.

I've improved API response times by 40%, reduced deployment time by 70%, and migrated a messaging service handling 17M+ messages daily from RabbitMQ to Kafka with zero downtime. I also deleted 684.6M production MongoDB documents without downtime and cut disaster-recovery time from 67 minutes to 21.

I'm currently building a production MCP server that exposes 25+ loyalty tools to AI assistants, using TypeScript, Node.js, and OAuth 2.1. I use AI coding agents alongside disciplined testing, code reviews, and clean-code practices to accelerate delivery.
