IoT Solution Architect | Industrial IoT (IIoT) | ThingsBoard | Edge | AWS & Azure I help companies design, build, modernize, and scale production-grade IoT & Industrial IoT platforms — from sensors, PLCs, and edge gateways to cloud infrastructure, APIs, data pipelines, and real-time dashboards. With 10+ years of IoT experience, 36+ projects, and 35,000+ connected devices, I combine hands-on engineering with solution architecture to build IoT systems that are scalable, secure, reliable, and maintainable in real-world environments. My strength is not limited to one layer of IoT. I work across the complete stack: Devices & PLCs → Industrial Protocols → Edge/Gateway → MQTT → IoT Platform → Cloud → APIs → Database → Dashboard 🔹 IoT & IIoT Solution Architecture • End-to-end IoT architecture and technical design • Edge-to-cloud architecture • Multi-tenant IoT platforms • High-volume telemetry ingestion • Real-time monitoring, alarms & event processing • Device provisioning and lifecycle management • High availability and scalable deployment architecture • Architecture reviews, modernization & performance optimization 🔹 Industrial IoT & Edge Computing • MQTT, OPC UA, Modbus RTU/TCP, DNP3, IEC 60870-5-104 • CAN / J1939 and telematics integrations • PLC, SCADA, RTU, sensors & industrial gateways • Python & Node.js edge services • Docker/Linux-based edge applications • Offline-first architectures and store-and-forward • Low-bandwidth and unreliable-network environments • Edge analytics and real-time data processing 🔹 ThingsBoard Expert — CE & PE Hands-on experience designing and implementing ThingsBoard-based IoT platforms: • ThingsBoard CE / PE architecture • ThingsBoard IoT Gateway • MQTT & Modbus integration • Rule Chains and data processing • Custom dashboards & widgets • Device provisioning and management • Multi-tenant architecture • PostgreSQL / TimescaleDB • Performance optimization and production deployment 🔹 AWS & Azure IoT AWS: IoT Core, Lambda, API Gateway, Timestream, DynamoDB, Kinesis, ECS/EKS, X.509, JITP/JITR Azure: IoT Hub, Device Provisioning Service (DPS), IoT Edge, Event Hub, Digital Twins, AKS, ACR 🔹 Connectivity, Backend & Data • MQTT / Mosquitto / EMQX • LoRaWAN / ChirpStack • Kafka and event-driven architectures • REST APIs & WebSockets • Node.js / Python backend services • PostgreSQL / TimescaleDB / Redis / InfluxDB • Grafana and real-time dashboards 🔹 DevOps & Production Deployment • Docker & Kubernetes • CI/CD pipelines • OTA updates • Device lifecycle management • Monitoring, logging & troubleshooting • Production scaling and performance optimization 🏭 Industry Experience I have delivered IoT solutions across Industrial IoT, Oil & Gas, Energy, Fleet & Telematics, Smart Buildings, Industrial Automation, and LoRaWAN-based systems. ⭐ Why Work With Me? ✔ 10+ years of hands-on IoT experience ✔ 36+ IoT projects delivered ✔ 35,000+ connected devices ✔ Strong Edge + Cloud + Industrial Protocol + Backend expertise ✔ Architecture-level thinking with hands-on development capability ✔ Experience taking systems from PoC → Production → Scale ✔ Strong focus on security, reliability, maintainability & performance ✔ Able to translate business requirements into practical technical architecture 🤝 How I Can Help Whether you are building a new IoT platform, modernizing an existing architecture, integrating industrial equipment, deploying ThingsBoard, designing an edge solution, or solving scalability/performance issues, I can help define and implement the right solution.
