About
I’m Sunil Kumar Pasupuleti, a results-driven Full Stack Developer with 3+ years of experience designing, developing, and deploying scalable, high-performance web and cloud applications using Java, Spring Boot, React.js, Node.js, and Python (FastAPI). I have hands-on experience building RESTful APIs, microservices, and serverless architectures across Azure and AWS platforms. I also enjoy turning ideas into robust backend services and delightful user interfaces that scale.
Outside core development, I founded Expenses Aura, a modern financial management application, and have strong FinTech domain expertise. I thrive in Agile teams, care deeply about clean code, security, and reliable CI/CD via Azure DevOps; I’m comfortable with .NET interoperability and basic ML pipelines when needed.
