About Me

Hi, I am Arnab 👋

👨‍🎓 I am currently a 3rd year UG pursuing my B.tech degree in Computer Science and Engineering from the Indian Institute of Engineering Science and Technology, Shibpur. Currently working on the Bitcoin-Core project as a part of the Summer of Bitcoin programme.

👨‍💻 I am a Software Developer with experience in Web Development, Automation, and Content Writing. For the past 2 years, I have worked around an immense variety of technologies and frameworks such as React, Vue in Frontend and Node, Flask, Rails in the Backend.

✨ Currently, I am working on my Data Structures and Algorithms and other Core CS fundamental knowledge. I use C++ as my primary language. I also have intermediate-level experience with Python, JavaScript, and Ruby. I often participate in Competitive Coding contests which aid my problem-solving skills.

💪 I’m always willing to participate in something that helps me learn and grow. From Hackathons to CTFs I love challenging myself and keep improving my skillset.

✍️ I also have a knack for Technical Writing, you can find my articles in Dev.to and my own blogging website @ arnabsen.netlify.app.

I’m always looking forward to learning, collaborate and hopefully make an impact.

Work Experience/ Internships

  • Summer of Bitcoin 2021

    Summer Of Bitcoin Observability means being able to see inside the running systems. It helps in troubleshooting, monitoring, and performance optimizations and plays a big role during development, debugging, code review, and production usage. eBPF (extended Berkeley Packet Filter) has revolutionized the observability landscape in the Linux kernel. With the help of this technology, I am working on improving the current User Statically-Defined Tracing (USDT) support in Bitcoin Core by adding new tracepoints and scripts.
