Location: Jackson, Mississippi, United States
Profile: https://flows.cv/sushil

I'm a Senior Software Developer with over 10 years of experience, specializing in backend development, API architecture, and scalable web application design. My core expertise lies in building and integrating RESTful APIs, working with Node.js, NestJS, and Ruby on Rails, and managing relational databases like PostgreSQL and SQL Server with strong SQL proficiency.

On the frontend, I have solid experience with React.js and Next.js, delivering performant and responsive user interfaces that connect seamlessly with backend services.

Recently, I’ve also worked on AI-enabled SaaS solutions, integrating Large Language Models (LLMs) like OpenAI into real-world applications. In my previous role, I led a team of developers, driving both architectural decisions and hands-on implementation.

I thrive on solving complex problems, optimizing systems, and staying current with evolving technologies. I'm currently exploring new opportunities where I can contribute my skills in backend engineering, API design, and modern web technologies.
