I’m a software engineer with experience in data engineering, embedded firmware, and backend development. I have worked with companies/clients build data workflows, automate repetitive tasks, and develop software for embedded applications. I can help with: • Python scripting, data processing, transformation, and automation • ETL pipelines using Microsoft Fabric and Pentaho Data Integration • SQL and database work with PostgreSQL, MySQL, and Microsoft SQL Server • Data modeling and dashboards with Power BI • AWS-supported data workflows using services such as S3, RDS, Lambda, Glue, and EC2 • Embedded firmware development in C and C++ using FreeRTOS and MQX • MCU programming and communication interfaces including CAN, SPI, UART, and I2C • Linux server development, Git, and unit and integration testing I’m an AWS Certified Cloud Practitioner and have hands-on experience with Microsoft Fabric, Python, relational databases, and embedded development. I value clear communication, reliable results, and code that is easy to maintain. If you have a data, firmware, or software project, tell me what you’re trying to build and I’ll be glad to discuss how I can help.
