Hi there! Seeking an expert in Java, Spring, Hibernate, Data Security, Angular, API (REST, SOAP), Node and additional technologies to achieve rapid transaction rate. Over the past 20 years, I have refined my skills through dedicated work in diverse domains such as Application/ERP Development, Application Integrations, Fintech, Oil/LPG Industry, Travel Industry, Education, Telecom , Web Development, Frontend Development, Application Customization, Performance Optimization, and Component Development. I have acquired extensive expertise in Java, Spring, Spring Boot, Spring Reactive, Spring Data, Spring Cloud, Spring Batch, IAM, OAuth 2.0, OpenID Connect, SAML, multi-factor authentication, Keycloak, REST API, SOAP API, JPA, Struts2, AWS Lambda, Hibernate, Node.js, Puppeteer, Next.js, Angular, React, Redis, Kafka, Rabbit MQ, JSP, Servlet, JSF, JavaScript, jQuery, HTML, CSS, XML, Lucene, JXL, POI, XSLT, JSON, JSON-LD, EJS, Python, GraphQL, Apache Airflow, Apache Spark, IBM Cognos, JasperReports, BIRT, Oracle, MySQL, SQL Server, PostgreSQL, IBM DB2, NoSQL, MongoDB, DynamoDB, Tomcat, OC4J, IBM WebSphere, WildFly, JBoss, Docker, Kubernetes, Bitbucket, GitLab, GitHub, RTC, CVS, VSS, Git, Confluence, JIRA, Maven, Gradle, Ant, Cursor, Replit Windsurf, Lovable, Trae, Bolt, Vercel and many more. To secure your data, I have expertise in both symmetric (e.g., AES, DES, Triple DES) and asymmetric (e.g., RSA, ECC) encryption mechanisms. I am also experienced in PGP / GPG encryption, which combines symmetric and asymmetric encryption to secure message content and protect the session key. Additionally, I have integrated applications with Hardware Security Modules (HSMs) for enhanced security. My goal is not just to meet but to exceed your expectations. My method for achieving project success revolves around: – Strategic Planning: Always look on a bigger-picture, make sure all angles are covered. – Agile Development: Adapt on the go, iterative progress yields positive results. – Quality Assurance: Attention to detail, ensure top-quality results by leaving no room for errors. – Timely Delivery: Time is valuable; meeting deadlines is crucial to avoid delays and extra costs. . – Transparent Communication: Clear and concise updates to stake holders. Always aim to collaborate with you, not just work for you, to ensure every milestone leads to success.
