Steven C.

I’m Steven Calinski, an Embedded Systems & Firmware Engineer with a passion for solving problems using software or hardware designs. I have a strong background in electrical testing as well as embedded firmware development. I’ve worked on critical embedded projects for fire alarm systems, mobile computing hardware, RF designs, and IoT applications, handling everything from firmware development to EMI mitigation, component level debugging, production testing, schematic design, and board layouts. Languages: C, C++, C#, Python, VHDL RTOS: FreeRTOS, Zephyr RTOS MCU Experience: STM32: F7, H7, H5, H4, Atmel SAM E, Renesas RA, TI MSP430, Silicon Labs, ESP32, ESP32-S3 Firmware Debugging & Optimization: USB, I2C, UART, SPI, PWM, DMA, MQTT, Cellular Network, Current limiting, Power, Battery backup switching, driver creation. I have a background in electrical test engineering as well and am comfortable with hardware troubleshooting, rework, repair, etc. I have a basic rework setup in my home. I am very familiar using Saleae logic analyzer, and oscilloscope to address signal integrity issues. Automated Test Development: LabVIEW applications for engineering & regulatory testing, ESP32 IOT projects for test automation. PCB Schematic Capture & Layout: Cadence Allegro, KiCad, Eagle Board Bring-Up & Component-Level Debugging: Rapid prototyping and validation Microcontroller & RF Circuit Design: Sub-1GHz RF design, BLE integration Click "Invite to Job" or "Hire Me", and let me help you develop your next project.
