During my training at HashedIn, I gained practical, hands-on experience across a diverse set of modern technologies, working on real-world challenges with the guidance of industry experts. Backend Development: I built robust backend services using Java Spring Boot and microservices, focusing on scalable architecture and efficient request handling through API Gateway implementations. I integrated Spring Security for JWT authentication and RBAC. Frontend Engineering: On the frontend, I developed Angular applications, utilizing Signals and JSON Web Server to create dynamic, seamless user experiences. I implemented AuthGuards and HTTP Interceptors to secure applications, deepening my understanding of the full development lifecycle from scratch to production. Generative AI: I explored cutting-edge Generative AI technologies, working with LangChain, LangSmith, AutoGen 0.4, MCP Server. I created Retrieval-Augmented Generation (RAG) systems, AI agents, document summarizers, and Q&A applications, leveraging vector databases for smarter information retrieval. Data Engineering: I designed ETL pipelines in Databricks using PySpark, managed real-time data streams with Kafka, and performed advanced analytics using SQL. I built solutions to simulate live match feeds and deliver real-time insights. .NET Development: I also worked with C#, microservices, LINQ, MySQL, and API Gateway in .NET, developing a hospital management project from scratch and applying end-to-end software design principles. Guided by the HU team’s mentorship, I solved complex problems and rapidly expanded my technical skills—excited to apply these capabilities in future projects.
