Requirement Analysis and Documentation as per SDLC methodologies. • Automated the Data Ingestion process using Shell scripts, Java Spark Library, Event Engine Console. • Worked on creating a data ingestion pipeline to cleanse, transform and filter data before creating ingestion files in parquet, CSV, text formats. Utilized SFTP to send these files for ingestion into hive tables. • Utilized a central batch streamer to transform Data into API requests in JSON & processed the response back to the required data format. • Utilized the Java 11 String library for the use for repeat, strip functions in data transforming and cleaning. Also used read/write String methods of Files library. • Utilized Microservices architecture for implementing business capabilities and CICD of the application. • Designed an approach for data movement from different sources to HDFS via Apache/Confluent Kafka.• Skilled in utilizing AngularJS with RESTful APIs to fetch and display data.• Worked on creation, optimization, updating HQL (Hive query Language) scripts. • Transformed existing hive scripts to Java SPARK for efficient performance and faster runtime. • Utilized Scala Spark to run monitoring scripts, post implementation validations, data sanity checks etc. • Proficient in integrating AngularJS with other front-end technologies such as HTML, CSS, and JavaScript.• Developed a UI using HTML, CSS, JavaScript, and backend functionality in JAVA for internal teams to add accounts to the daily matching process. • Worked on AWS cloud services i.e. EC2, S3, RDS, ELB and EBS for installing, configuring & auto scaling.

Requirement Analysis and Documentation as per SDLC methodologies. • Developed different modules using Java, Spring Boot and Hibernate. • Used Spring Batch and Spring Boot for dependency injection, batch processing and implementing Micro services. • Involved in development of service-based architecture utilizing open-source technologies like Hibernate ORM with JPA Annotations and Spring MVC Framework. • Integrated Spring (Dependency Injection) among different layers of an application. • Worked on migrating Persistence layer from simple DAO to Spring/Hibernate. • Designed and developed a RESTful APIs using Spring REST API. • Used Java 8 Lambda Expressions to rewrite certain parts of the code.• Proficient in AngularJS for developing dynamic and interactive web applications.• Developed helper classes, delegate classes, value objects to access business tier and transfer the information from business layer to the presentation layer. • Configured and deployed the application using Tomcat Application Server. • Designed and implemented business logic and data processing routes using Apache Camel.• Used Hibernate as persistence framework for DAO layer to access the Oracle11g database. • Designed and developed database objects like Stored Procedures, Functions, Triggers, PL/SQL packages and Cursors for Oracle.• Utilized Microservices architecture for implementing business capabilities and CICD of the application. • Used Maven for build framework and Jenkins for continuous build system.

Involved in analysis, design, and development of e-bill payment system as well as account transfer system and developed specs that include Use Cases, Class Diagrams, Sequence Diagrams and Activity Diagrams. • Involved in all the phases of (SDLC) including Requirements Collection, Design & Analysis of the Customer Specifications from Business Analyst. • Developed RESTful Web services for the services to get the data from external systems to process the request from client sides.• Used Spring Framework for Authentication and Authorization and ORM components to support the Hibernate tool. • Designed and developed Application based on Spring framework using MVC design patterns. • Responsible for writing/reviewing server-side code using Spring JDBC and DAO module of spring for executing stored procedures and SQL queries. • Worked with Core Java for business logic. • Designed and developed the business logic layer and data access layer using different kinds of EJB's and Data Access Objects (Dao's). • Used JSON for validation, documentation data required by a given application. • Followed the Agile methodology to implement the application.
