Founder and CEO of Devana

About

I am the founder of Devana, an AI-powered mock interview platform for software engineers preparing for technical interviews. I am responsible for the full scope of the business, including product development, content strategy, and growth. The idea for Devana originated from personal experience: I could reliably solve technical problems on my own, but consistently struggled to perform when required to explain my reasoning live, under observation. That gap between solitary competence and live performance became the foundation for how I designed the product and approached distribution. I am currently focused on growing Devana through organic, content-led distribution, and on converting our early user base into paying customers.

Devana - AI technical mock interviews for software engineers

Devana is an AI interviewer for technical rounds. It conducts live voice interviews with a real code editor, asks follow-up questions based on your approach, and prompts you when you go quiet for too long. Most interview failures aren't about problem-solving ability; they happen because candidates have never practiced explaining their reasoning out loud under observation. Devana was built to close that gap, with coding, system design, and behavioral formats supported.
