● Project 1# : https://www.advaneo-datamarketplace.de/en/# ● Project 2# : https://tdh.advaneo.com/page-login Implemented search operation for data from millions of datasets, where the FilterEntities, FilterQuery, Common Query builder classes are implemented in java 11 with elastic search api integration, which gives excellent performance and scalability ● Implemented for all the project/modules with Basic authentication using spring controller and authorization by integrating keycloak Api using spring rest templates which ensures users security and integrated hubspot api for storing contact information of the users for marketing team ● Implemented asynchronous logging mechanism by using SLF4j, log4j, across all the services by categorizing logs at different levels such as trace, debug, info, warning, error and Fatal and also formatting the output logs ● Implemented Java Error handling mechanism by separating from Regular code using java built-in exceptions, try, catch, finally, throw and throws example: all the services dealing with file system so the errors are handled if file cannot be opened, if the size of the file cannot be determined, if enough memory cannot be allocated, if the file read fails, if the file cannot be closed and furthermore on business logic specific ● Integrated amazon aws simple email services using template emails and pushed templates from aws command line interface Here this is achieved by spring framework for the needed dependency injection and annotation based configurations ● Implementation of allowing users from spring boot to interact with mongodb via MongoTemplate and MongoRepositories for operations like update, aggregations, and others, controlled overcustom queries ● Worked on docker composing and defining project-specific dependencies and build-time tasks that will build and deploy each container ● Monitoring tool called watch-tower is containerized inorder to monitor and send messages in slack channel if any incident occurs in the production environment ● Responsible for configuring and maintaining docker bash script for production environment and making sure the application is reliable Responsible for production enhancements and bug fixing

* Contributed to all phases of the development lifecycle, from design to writing and
developing.Wrote well designed, efficient and reliable code for data applications,
completing within deadlines.Converted application storyboards and use cases into
functional applications by writing, testing and debugging Java code by using java
frameworks Angular 10+, Spring, Hibernate, Spring boot.
* Created reusable libraries, modules and packages, decoupling application
components and improving maintainability. Java API Integrations such as Keycloak,
AWS, Hubspot and other Microservices integrations
* Understood JVM's limitations, weaknesses and workarounds and used knowledge
to create secure, high-performance and stable software. Tested software throughout
development, identifying and removing errors for stable and reliable software
products.
*Analysed user requirements before starting Java development projects to
understand application layout and design. Conducted in-depth assessments of Java
infrastructure to determine and recommend changes needed to improve design and
performance.
*Maintained extensive knowledge of Java and JEE internals, using skills to debug and
resolve technical problems. Employed versioning tools and technologies to control,
monitor and log changes to application code.
*Assessed existing systems and recommended patches, fixes or design overhauls to
fix broken code. Fault-found and resolved issues arising within development life
cycles by testing applications.
*Executed build tools to produce packages and executables for testing and shipping
to clients. Charted data flows, processes and storage and defined database schemas
representing and supporting different business functions.
*The build process carried by using Jenkin, bamboo, docker, watchtower(monitoring
tool).Participated in technical reviews and meetings to refine and refactor software,
maintaining code quality(Sonarqube), organisation and performance. Specified
application objectives and functionality after reviewing technical diagrams,
specifications and documents.
