I’m Sonica Rathore, a full-stack engineer with 14+ years of experience building SaaS products, web apps, APIs, and backend systems. Most of my work has been with startups and growing product teams where I’ve handled everything from frontend development to backend architecture and deployment. I work mainly with React, Angular, TypeScript, Python, PostgreSQL, MongoDB, AWS, Docker, and Kubernetes. Over the years I’ve built: SaaS platforms Internal tools and admin panels Backend APIs and automation systems Dashboards and workflow tools Scalable cloud-based applications I’m comfortable working independently, handling product decisions, improving existing systems, and building new features from scratch. I care a lot about writing clean code and keeping things maintainable because projects get difficult very quickly when the foundation is messy. I also prefer keeping communication simple and practical — clear updates, realistic timelines, and no unnecessary process. If you need someone who can build reliably, solve technical problems, and work without constant hand-holding, feel free to reach out.
