Saif J.
Flutter & Next.js Developer | Industrial Apps, 3D/AR & Cloud
I build cross-platform apps for industrial teams, and I’ve shipped them in production. At One Motion I built a Flutter and Next.js app that gives technicians access to records for thousands of industrial motors. Google ML Kit label scanning pulls a motor’s data in under 10 seconds, and a QR asset-identification flow opens a machine’s maintenance history from the backend API. I also build the web side: Next.js sites with 3D models converted from STEP CAD files, a product configurator, and APIs fed by Quickbase. At INDAUTECH I was the sole developer on a robot-cell automation system: a SCARA robot, barcode scanning and Siemens TIA Portal PLC control for pick-and-place. I connected it to web dashboards over REST APIs, so operators can monitor the whole line from a browser. I also build AR: a multiplayer mobile AR game with Unity, Photon and Vuforia, and an AR-enhanced industrial monitoring app. Cloud and DevOps are my second strength: AWS infrastructure in Terraform, GitHub Actions deployments that sign in to AWS with OIDC (no stored keys), and a private OpenStack cloud monitored with Prometheus and Grafana. Send me the platforms, any existing code, and any device or integration constraints. I’ll reply with a plan and a quote.
