The most amazing...
...experience I've had was analyzing the load on a microservice, learning the basics of Scala, and developing its entire load testing framework in just two weeks.
Work Experience
Software Development Engineer II
Amazon Web Services (AWS)
- Designed, built, and integrated services that protect AWS account Sign-Up, Sign-In, and Single Sign-On (SSO) from security threats.
- Handled service integration with other internal intelligence services, driving cross-team collaboration and decisions.
- Understood customer requirements and analyzed live traffic to identify solutions that can increase the security posture of AWS Identity.
- Managed real-time security events as part of on-call support.
- Defined AWS cloud infrastructure using CDK: Involved learning basics of TypeScript.
Java Developer
Fontana Engineering Group LLC (via Toptal)
- Developed an API that will build a path from the trust anchor to the EE cert and determine whether the certificate is valid when the specified certificate policy is asserted. I studied the Java Crypto and Bouncy Castle libraries to achieve this task.
- Upgraded the existing smart card validation software from Java 8 to Java 11, from JUnit 4 to JUnit 5, and from Gradle version 4.3 to 6.6. I learned and applied Java modules during this upgrade.
- Fixed bugs and made enhancements to the GUI, applying the basics of Swing for this task.
- Added and enhanced JUnit tests to ensure product stability and prevent regressions. Special behavior was required because the application also ran JUnit 5 to validate PIV cards.
Software Engineer
VMware
- Developed REST APIs to access and store user entitlement details in a database, focusing on caching for performance, encryption for confidential data, hashing for passwords, and versioning for backward compatibility.
- Served as the key developer for an Okta-VMware partnership project and developed endpoints to support launching the Okta apps through Workspace ONE.
- Designed and developed a microservice that provides authentication/authorization features based on OAuth 2.0 and OIDC protocols. I built the infrastructure using AWS and the deployment pipeline using Jenkins.
- Worked on several features and bugs related to reading/writing SAML requests and responses.
- Organized bimonthly scrum meetings to divide projects into sprints and performed retrospectives on their execution at the end of each sprint.
- Performed continuous monitoring with on-call duty. The product was a SaaS application with a high SLA. The tools used were AWS CloudWatch, AWS Management Console, PagerDuty, and Slack.
- Understood the load on the service to perform horizontal and vertical scaling of EC2 servers as required.
Teaching Assistant
Indian Institute of Technology Madras
- Served as a teaching assistant for key computer science courses such as Principles of Software Engineering, Discrete Mathematics, Automata Theory and Logic, and Combinatorics.
- Guided and mentored students as they built their first software projects across a semester. I held weekly office hours to help students understand concepts and clarify their doubts.
- Evaluated and graded the students through tests and examinations. I interacted with low-performing students to understand their issues and discussed the feedback with faculty.
Team Lead
Altair India Engineering Private Limited
- Developed features based on requirements from customers in the aerospace and shipping industry. These features required full-stack development.
- Implemented the UI using Tcl/Tk, and the back-end API was in C++. An extensive set of automation tests were written for each new API.
- Designed visualization tools to graphically display entities such as nodes, edges, loads, forces, directions, and connectors.
- Trained new team members and interns on the product and supported them on their projects.
Software Engineer
Altair India Engineering Private Limited
- Supported FiberSim and HyperMesh interoperability using HDF5 files.
- Built an Excel and CSV file reader and writer using C++ for data exchange between HyperMesh and CATIA.
- Developed build verification tests using Tcl, an extensive test suite to catch regressions after a new feature is added to software.
- Tracked and fixed numerous bugs in HyperMesh software.
