At Sustainable Infrastructure Company, I developed responsive IoT dashboards, including the Thermal AC Cineplex Control application, and Azure services for processing sensor telemetry.

I also built GIS mapping interfaces and a digital twin configurator for electrical panels, with role-based permissions, validation, and audit history to protect live infrastructure layouts.

At Ketene IT Service Company, I established Fastlane CI/CD pipelines for iOS and Android deployments and implemented cloud-native backend services using AWS, Firebase, and Azure.

Since 2019, I’ve worked as a Freelance Software Engineer on custom mobile and web solutions. I use AI-enhanced development workflows and continue delivering full-stack engagements through Fiverr, Toptal, and Upwork.
