Chi sono
Building electronics since age 13, I am a Senior IoT Engineer who bridges the gap between hardware and software. I don’t just write code; I design custom PCBs, write robust Firmware (ESP32/C++), and build industrial-grade systems for Automation.
My specialty? End-to-End IoT. I take your idea from a rough sketch to a manufactured product (PCB + Firmware + Cloud Dashboard).
I have worked with Government Ministries and Universities to turn research into reality. If you need a professional engineer—not just a hobbyist—to build reliable hardware, let's talk.

Senior Internet of Things Engineer
Nexus Fish Network • Freelance
Jan 2025 - Present • 1 yr 4 mos
Lead Engineer for R&D of "SmartFishAuto™," Bangladesh's first AI-driven aquaculture automation ecosystem. Architected a unified IoT network of 3 device classes communicating via custom MQTT APIs. Key Projects: Industrial Sensor Nodes (SEN v2): Designed ruggedized, floating water profilers using ESP32 & Modbus RS485. Transitioned to industrial probes (DO, pH, ORP) on custom PCBs (JLCPCB) with Solar BMS, reducing field maintenance by 60%. Smart Automation (SW Series): Built 8-Channel Intelligent Switching Units for heavy AC loads. Implemented "Oxygen-Demand Logic" to trigger aerators only when needed, cutting energy costs by ~25%. Predator Defense (LR Series): Developed "AvianGuard," a dual-axis laser turret for automated bird deterrence. Technical Stack: Firmware: C++ on ESP32 (Dual Core) using FreeRTOS & Deep Sleep. Hardware: 2-Layer Custom PCB Design (EasyEDA) & Prototyping. Connectivity: MQTT Telemetry to Cloud Dashboard & Mobile App.
