I have experience in software development using Java, Python, and C++. I have worked on various projects that involved web development, machine learning, and system programming. My most recent project involved developing a web application using React and Node.js.

I approach problem-solving by first understanding the problem and then breaking it down into smaller, manageable parts. For debugging, I use tools like GDB or browser developer tools to identify the root cause of issues. I also write unit tests to ensure that my code works as expected.

The software development lifecycle includes stages such as planning, analysis, design, implementation, testing, deployment, and maintenance. My role typically involves participating in design and implementation, writing and reviewing code, and conducting unit and integration testing.

I have experience working in agile environments where we use Scrum or Kanban. I contribute to the team by participating in daily stand-ups, sprint planning, and retrospectives. I also prioritize tasks and work collaboratively with team members to deliver high-quality products.

I ensure quality by writing clean, maintainable code and conducting thorough testing, including unit, integration, and acceptance tests. For security, I follow best practices such as input validation, using secure APIs, and regularly updating dependencies. I also perform code reviews to catch potential issues early.

One challenging project involved migrating a legacy system to a more modern architecture. We faced issues with data consistency and system downtime. I handled these challenges by planning a phased migration, ensuring data was backed up, and writing scripts to automate data transfer. Close communication with the team and stakeholders was crucial to mitigate risks and manage expectations.
