Software Engineer | Python • FastAPI • Django | Building reliable backend systems & practical tools

About

Growing up, I was always curious about technology. It started with games and websites, but that curiosity eventually led me to study Computer Science and Engineering. The moment I started building applications with Python, Django, and FastAPI, I knew software engineering was where I wanted to be. I enjoy solving backend problems, designing APIs, automating repetitive workflows, and building software that's reliable, maintainable, and genuinely useful. Whether it's developing internal tools, building web applications, or experimenting with AI-powered solutions, I enjoy turning ideas into products that solve real problems. My experience spans backend development, freelance web development, and enterprise product operations, where I've worked closely with developers, support teams, and customers. That exposure has taught me to write cleaner code, stay calm under pressure, take ownership, and understand software from both the engineering and user perspectives. Some of the projects I've enjoyed working on include production tools at Carestack, freelance web applications like WahnDesign, computer vision experiments, and personal projects that challenge me to learn new technologies. Every project has strengthened my belief that the best software isn't the most complex—it's the software that people can depend on. I'm currently looking for an entry-level Software Engineer opportunity where I can contribute, keep learning from experienced engineers, and build products that make a real impact. If you're hiring, building something interesting, or simply enjoy talking about software, feel free to reach out via LinkedIn DM or email at sahalmsachu@gmail.com.
