Karat created the world’s first Interviewing Cloud to make the technicalinterviewing process fair, equitable, and enjoyable. Brilliant Black Minds, a freeprogram by Karat, exists to increase the number of Black software engineers intech. As an ambassador for the program, I support a community of thousandsof Black software engineers as they practice for technical interviews andunlock access to new career opportunities.

Spearheaded the development of core features for a FinTech startup, delivering a Minimum Viable Product (MVP) from scratch, including web scrapers, dynamic UI components, AWS cloud infrastructure, and comprehensive test coverage.Engineered and deployed scalable Python scripts using AWS Lambda, automating real-time web scraping to capture and notify clients of newly published financial data within 12 hours of release, significantly improving client responsiveness.Created robust… Show more Spearheaded the development of core features for a FinTech startup, delivering a Minimum Viable Product (MVP) from scratch, including web scrapers, dynamic UI components, AWS cloud infrastructure, and comprehensive test coverage.Engineered and deployed scalable Python scripts using AWS Lambda, automating real-time web scraping to capture and notify clients of newly published financial data within 12 hours of release, significantly improving client responsiveness.Created robust custom Python exception handling frameworks for web scraping processes, ensuring >80% unit test coverage for edge cases such as missing elements, invalid URLs, and file type errors, leading to more reliable and maintainable code.
