What I'm looking for

I'm looking to build scalable web, mobile, and AI-powered products, contributing to production LLM features, automation, secure cloud delivery, and high-impact engineering outcomes.

I've built secure SaaS products at GitWork/Phebsoft serving 10K+ daily active users, reducing API response times by 38% through query optimization and caching. I also ship Flutter apps to the Apple App Store and Google Play Store with subscriptions, in-app purchases, and push notifications.

Across ZettaByte and WebRange Solution, I've architected Node.js and React microservices, improved deployment scalability by 60%, and boosted enterprise application performance by 50%. I've also delivered agentic AI workflows, n8n automations, AI chatbots, and LLM-powered product features using OpenAI and Claude APIs.

I'm experienced in dependable production delivery, from AWS ECS deployments and load balancing to Docker-based CI/CD, monitoring, security controls, and zero-downtime releases. My project work for ME Commercial Ohio improved system reliability by 45% while delivering across time zones ahead of schedule.
