Sanjay Malakar

I am a senior software engineer at OpenRefactory, Inc., a Silicon Valley-based deep-tech software company that focuses on automatically fixing security, reliability, and compliance bugs.

My research focuses on Software Engineering, Software Security, and Programming Languages.

I received my Bachelor of Science degree in Computer Science and Engineering from Bangladesh University of Engineering and Technology. I completed my undergraduate thesis under the supervision of professor Dr. Rifat Shahriyar on addressing atomicity bugs in software. Besides that, I worked with Dr. Gias Uddin, Assistant Professor, University of Calgary, and Dr. Anindya Iqbal on an empirical study of low-code software development challenges.

Apart from my academic activities, I like to travel to new places with my friends and family. In my free time, I enjoy solving problems on data structure and algorithms, watching anime, and playing FPS games.

Software Engineer

OpenRefactory, Inc.

Worked on Intelligent Code Repair (iCR), which is a static analysis-based bug detection engine that (1) detects bugs that other tools miss, (2) does that with dramatically low false warnings, and (3) is the first and only tool in this space that can also synthesize fixes automatically for over half of all the bugs detected. Worked on iCR for Java. Key responsibilities:

  • Contributed to the core IP of iCR by working on the static program analysis.
  • Developed and implemented algorithms for a pointer analysis engine.
  • R&D on software weakness and vulnerabilities.
  • Contributed to the CI/CD pipelines.

Developer Discussion Topics on the Adoption and Barriers of Low Code Software Development Platforms

Co-Authors: Md Abdullah Al Alamin, Gias Uddin, Sadia Afroz, Tameem Bin Haider, Anindya Iqbal

The Empirical Software Engineering (EMSE) journal invited us to extend our MSR'21 paper titled, An Empirical Study of Developer Discussions on Low Code Software Development Challenges. We applied topic modeling to 33K relevant Stack Overflow posts of 38 popular low-code platforms and manually annotated statistically significant data samples to reach our conclusions.

Status: Accepted in 2023 Elsevier Empirical Software Engineering Journal (EMSE). [PDF] [CODE]

An Empirical Study of Developer Discussions on Low-Code Software Development Challenges

Co-Authors: Md Abdullah Al Alamin, Gias Uddin, Sadia Afroz, Tameem Bin Haider, Anindya Iqbal

We presented a novel empirical study of around 5K Stack Overflow posts that contain discussions of nine popular low-code development platforms. We presented the low-code platform trends and discussed the difficulties that developers encounter while adopting these platforms. Our findings offered implications for low-code practitioners, platform providers, educators, and researchers.

RaceFixer - An Automated Data Race Fixer

Co-Authors: Tameem Bin Haider, Rifat Shahriyar

We developed a Clang-based tool that automates fixing single-variable atomicity violations. We utilized the bug reports of an existing bug-detection tool, ThreadSanitizer. We augmented them with static analysis to construct a suitable patch for each bug report, with the best effort to reuse locks and avoid deadlocks.

Status: In preparation for Concurrency and Computation: Practice and Experience..
