Worked as an embedded systems engineer at a technology company where the role covered the full development cycle — from initial hardware selection and schematic review through to firmware development, testing, and deployment. Wrote and maintained firmware for STM32 and AVR microcontrollers across multiple internal products, working closely with hardware engineers to resolve integration issues early in the design phase. Handled implementation of communication protocols including I2C, SPI, UART, and CAN bus across different product lines. Took ownership of debugging sessions on both hardware and software sides, using oscilloscopes, logic analyzers, and serial monitors to trace and resolve issues that weren't visible at the code level alone. Also contributed to motor control projects involving BLDC and stepper motors, tuning PID loops to meet real-world performance requirements. Worked within structured development timelines and collaborated with cross-functional teams on documentation, testing procedures, and client-facing technical reports. Freelance Embedded Systems Engineer — Fiverr June 2025 – Present freelance after building a solid technical foundation in industry. Now working with international clients on IoT devices, automotive systems, and industrial embedded applications. Delivered 14+ projects spanning STM32, ESP32, Arduino, and Raspberry Pi platforms, with work ranging from single-module firmware to full system builds that include cloud integration, custom dashboards, and multi-processor architectures. Key Achievement Delivered a complete automotive Body Control Module on STM32F4 and ESP32 — covering dual CAN bus communication, FreeRTOS task scheduling, FRAM-based persistent configuration with CRC validation, real-time WebSocket monitoring, and OTA firmware updates — across a three-month milestone-based engagement with full client approval at every stage.
