Backend developer with experties in node.js/ Typescript services using Cloud AWS, build mobile apps using Flutter/Dart.
IndiaWhat I'm looking for
I’m a Backend Software Developer focused on IoT-connected products—designing microservices, secure authentication, and real-time messaging to make distributed devices reliable. I’ve architected FOTA workflows and state tracking that support remote firmware flashing at scale.
In my current role, I built an AWS IoT Core command service using MQTT with AWS Kinesis and Redis Pub/Sub for low-latency bidirectional communication. I also delivered telemetry pipelines with AWS Timestream and InfluxDB, including RESTful APIs for frontend dynamic graph plotting, plus incident triage and CloudWatch-driven production monitoring.
I also build across the stack: I shipped a Flutter BLE app with 5,000+ organic downloads, integrated FOTA via Node.js on AWS EC2, and used BLoC for clean state management. Previously, I delivered a production-ready C# .NET WPF desktop app for BMS monitoring across field engineers and units, combining checksum-based UART/USB protocol reliability with Python.NET analysis and reporting.
