What I'm looking for

I’m looking for backend work where I can build clean, secure APIs, optimize database performance, and ship reliable services with good testing, logging, and observability.

I’m a Software Engineer Trainee at Digital Trust Technologies, where I design backend services in ASP.NET Core using clean architecture, Entity Framework Core, and PostgreSQL. I’ve optimized complex dashboard queries to reduce execution time and database load, and I’ve added structured logging, health checks, and readiness probes for better observability.

I also built REST APIs during my Java Developer internship at Technical Hub Pvt Ltd using SQL/JDBC and worked with Git, IntelliJ, and Postman to deliver endpoints. For projects, I developed a full-stack Blogging Application with React and Firebase/OAuth plus MongoDB + Express REST APIs, and I created a Spring Boot REST API with Spring JPA/Hibernate, pagination, sorting, and Swagger documentation.
