An Android-based app that delivers effective protection for mobile devices. It has a number of security-related functionalities, including device security protection against vulnerabilities such as insecure configurations, untrusted certificates, malicious apps, and insecure websites. The app also has an identity protection feature that protects the user's identity from misuse and a secure virtual private network (VPN) that allows users to securely connect to the internet.

I was working as one of the core developers for the product.

My responsibilities included but were not limited to the following:

• Worked with PM to make clarifications on the requirements. They needed to understand certain tech, and I needed to understand more of the business.
• Product feature design and implementation.
• Code review and pair programming.
• Mentored junior engineers/interns and knowledge sharing.
• General innovation

The company wants to expand Identity services (credit monitoring, data breach notification, dark web monitoring, etc.) to the Japanese market.

My Scrum team of five was chosen to make changes to mobile apps (Android and iOS) and corresponding back-end changes.

I happened to know about the tech stack (React) used in the back end. I set up the development environment, ran the server, laid out some fundamentals for the changes, and demonstrated them to the team.

I then shifted to making mobile app changes and let the rest of the team continue to work on the back-end so that everybody could learn something new.

I even surprised myself by making all the mobile changes for the project and having the code reviewed and tested by the team. Then I went on to test the web changes.

I am incredibly proud of this small project where we had fantastic learning and collaboration.

This initiative for the team and project is to create tool stacks and methodologies to test technical documents of Microsoft Windows client communication protocols.

One example protocol technical document:

I was mainly responsible for the following:
• Extracting requirements from the technical document
• Creating a model (finite state machine based) to auto-generate test cases
• Analyzing network packages captured during test case run to troubleshoot issues
• Raising bugs for document defect
• Writing technical documents like PQAR (Protocol Quality Assurance Report)
