Crafting Robust Backend Solutions

Hi, I'm a passionate backend software engineer who excels at solving complex problems and delivering impactful solutions. I specialize in designing scalable systems, building robust APIs, and optimizing performance for critical applications. With experience in open-source contributions, mentoring, and end-to-end development, I bring leadership and a collaborative spirit to every project.

Outside of work, I'm deeply curious about psychology and human behavior, and I love reading books that inspire fresh perspectives. I enjoy exploring how technology, strategy, and human interaction come together to create meaningful outcomes. Letss connect to discuss ideas, projects, or anything that sparks curiosity!

Open Source Contributor

2020 - 2022

Contributed to multiple open-source projects including Django REST Framework, Mathesar Foundation, and various web applications, focusing on feature development, testing infrastructure, bug fixes, and performance improvements. Demonstrated expertise in both frontend and backend development while collaborating with global development teams through Git workflow.

  • Enhanced Django REST Framework's permission system by fixing a critical flaw in the DjangoModelPermissions class, properly implementing view permissions to respect both explicit view permissions and implied read access from change permissions.
  • Strengthened database integrity testing in Mathesar Foundation by implementing end-to-end tests for table name collision scenarios and schema validation, preventing potential data corruption issues.
  • Developed comprehensive integration tests for data type conversion operations, specifically focusing on text-to-number column transformations, ensuring data integrity during schema modifications.
