Dibyendu Bhattacharjee

I’m a B.Sc. Cybersecurity Graduate and freelancer with a solid technical foundation in Python programming, network security, and threat detection. I enjoy turning complex security problems into working tools, especially when AI and machine learning can help.

Through my projects, I’ve built authentication and bot-resistance solutions like a MazeCAPTCHA System that uses a maze-solving mechanism to validate user authenticity. I also created a Turnstile-style CAPTCHA Breaking Prototype by analyzing human-computer interaction patterns such as mouse movement, speed, and entropy.

I bring hands-on experience that complements my security work, including roles as a Community Mgmt. & Operations Analyst Intern and a Data Annotation Expert. I’m comfortable working with data workflows and using tools like Tableau, MS Excel, and Power BI to understand and communicate results.

My professional ethos is to learn fast, collaborate well, and deliver impactful security contributions in innovative teams. I’m eager to apply my blend of cybersecurity and analytics to real-world problems with measurable outcomes.
