Embedded Systems & IoT Engineer I Worked on the development of embedded systems and IoT solutions for smart devices and connected products. My role focused on building reliable microcontroller-based systems that can collect sensor data, communicate with cloud platforms, and automate real-world processes. I designed and implemented firmware for microcontrollers such as ESP32 and STM32, integrating sensors, wireless communication modules, and control systems depending on the project requirements. Many of the systems were built for real-time monitoring, automation, and remote device control. I also assisted in creating early-stage IoT prototypes by combining hardware design with embedded programming. This included sensor integration, wireless communication setup, and testing device performance under real operating conditions. Part of my responsibilities involved troubleshooting embedded systems, optimizing firmware performance, and ensuring stable communication between devices and IoT platforms. I worked closely with hardware design processes to ensure smooth integration between the PCB hardware and the embedded firmware.

Mechanical CAD and Product Design Engineer Worked on mechanical product development and 3D CAD design for prototypes, consumer products, and manufacturing components. My role focused on transforming ideas, sketches, and engineering requirements into accurate 3D CAD models and production ready technical drawings. I created detailed mechanical parts, assemblies, and product designs using professional CAD tools, ensuring that each model met engineering standards and manufacturing requirements. Many of the projects involved preparing models for 3D printing, CNC machining, and product prototyping I also supported product development by converting 2D concepts into full 3D mechanical models, producing assembly drawings, and preparing dimensioned technical documentation for manufacturing teams. Part of my work included improving designs for manufacturability and functionality, reviewing component fits, and helping optimize mechanical structures before production. I collaborated on prototype reviews, design revisions, and mechanical testing preparation to ensure products were ready for real-world use.

Dec 2022 - Nov 2025 • 2 yrs 11 mos

Electronics & PCB Design Engineer Worked on designing electronic systems and PCB layouts for embedded devices, IoT products, and automation projects. My work focused on turning ideas and rough concepts into functional electronic hardware that can be tested, improved, and eventually manufactured. I handled both the schematic design and the PCB layout process, making sure circuits are stable, efficient, and practical for real-world use. I also worked with microcontroller-based systems such as ESP32 and STM32, integrating sensors, power management components, and communication modules depending on the needs of each project. During development, I assisted with prototype testing and troubleshooting to identify design issues early and improve system reliability. Part of my role included preparing PCB files and documentation needed for prototyping and manufacturing, such as Gerber files and component lists. I regularly optimized board layouts to improve signal flow, reduce noise, and ensure proper power distribution across the circuit.
