What I'm looking for

I'm looking to build clean, scalable web applications and backend systems while collaborating with cross-functional remote teams. I value opportunities to solve integration, monitoring, and technical troubleshooting challenges that improve reliability and efficiency.

At Twin Cities Tech Solutions, I build and maintain REST APIs and integrations with JavaScript, Node.js, and React.js. I led a transition to digital booking and management platforms that cut operational costs by 30% and improved efficiency by 10%.

I've debugged and refactored backend systems to improve runtime efficiency by 50%, reduced downtime by 25% through monitoring and log analysis, and integrated 10+ third-party APIs and SDKs without critical failures. I also support AI/NLP data validation, API testing, technical documentation, and remote cross-functional teams.
