Suman Karki

I build secure Java backend applications with Spring Boot, Spring Security, Spring Data JPA, Hibernate, and MySQL. My work centers on REST APIs, authentication, authorization, transaction handling, and reliable relational data design.

At Saauzi Smart Solutions Pvt. Ltd., I developed and maintained production web application modules using Nuxt.js, TypeScript, and REST API integrations. I contributed across feature implementation, debugging, API testing, maintenance, code reviews, and Agile development.

I built FinFlow, a banking management backend with APIs for accounts, deposits, withdrawals, transfers, transactions, roles, notifications, and audit operations. I implemented JWT authentication, role-based authorization, validation, centralized exception handling, Docker containerization, Swagger documentation, and GitHub Actions CI/CD workflows.

I’ve also developed microservices, e-commerce, and hospital management backend projects. I use Docker, Git, Maven, GitHub Actions, PostgreSQL, MongoDB, Redis, and cloud deployment concepts, and I’m interested in scalable backend architecture and production-ready software.
