Java Backend Developer at Zillionica Technologies building trading APIs and integrating 12+ financial brokerage APIs.

At Zillionica Technologies Pvt Ltd, I develop microservices and RESTful APIs for an algorithmic stock trading platform, supporting trading operations and analytics.

I integrated 12+ financial brokerage APIs using Feign Client. I also implemented secure authentication and role-based access control with Spring Security and JWT.

I optimized MySQL queries and JPA/Hibernate data access, reducing response latency by 30%. I used the Factory design pattern and SOLID principles to support reusable, modular code.

Earlier, as a Java Developer Intern at AHOMTechnologies Pvt. Ltd., I built backend modules with CRUD operations and data processing pipelines using Core Java and JDBC, and worked with SQL queries, stored procedures, and indexing for MSSQL Server.
