Cognizant Technology Solutions•  November 2020 - Present•  Bengaluru

I'm a Software Engineer at Cognizant, where I've focused on backend development using Java and SQL, particularly with Spring Boot. I'm comfortable with IntelliJ IDEA and Eclipse, and I'm proficient in MySQL databases and Git/GitHub for version control. I've also used JIRA for project management. I'm interested in becoming a full-stack developer, so I'm looking to learn HTML, CSS, and JavaScript, as well as frameworks like React and Angular. I have experience with ACI's BASE24-pos and BASE24-atm applications, specializing in online payments and e-commerce, including authorization, clearing, settlement, and working with payment schemes like VISA and MasterCard. I'm also knowledgeable about acquiring/issuing systems and ATM/POS authorization switches using debit and credit cards. I have programming experience with TAL and TACL, and I'm strong in debugging and troubleshooting.
