Senior Software Engineer | August 2015 – March 2017
Software Engineer | February 2013 – July 2015
Junior Software Engineer | April 2011 – January 2013
  • Major technology upgrade in enterprise application: Created web-based cross-browser multi-threaded file transfer library to send files larger than 100+gb. It replaced the old java applet-based library that only supported megabytes of non-resumable transfer.
  • Introduced resumable file transfer in encrypted data: Implemented file download pause/resume support for encrypted files by implementing random access in the java input stream by using block-by-block decryption of AES.
  • High availability file system design:Developed (lead the product development with 2 other junior SWE) a hierarchical file system using SQL and java to support high availability. Developed complete file system frontend tree explorer user interface from scratch using AngularJS.
  • Large file compression: Implemented GZ file compression in java to compress large files in the server.
  • Audit logging: Developed architecture of audit logging module with log versioning support using reflection.
  • Security layer architecture:Added proper permission check and validation in business logic using template pattern.
  • Tech Stack: Spring, Struts, Java, Java EE, Hibernate, JPA, JavaScript, AngularJS, MySQL, Postgres, REST

Most Frequently used


Pipilika Search Engine

  • Proposed and developed a prototype for the first-ever Bangla search engine named ”Pipilika”.
  • Conducted R&D on web crawling, indexing of joint Bangla alphabets, and integrated distributed systems (Hadoop). Proposed and developed a generic content parser with 80% accuracy.
  • Pitched and demonstrated the product on several occasions and received several awards. Upon receiving 1M funding from Telenor, we launched it to production in 2013. Our work has been featured in several national news media.
  • Since then it has served as a data platform for researchers at SUST, leading to several NLP research publications.

Paperless Admission System

  • Automated and digitalized admission of SUST. For students, it reduced traveling across the country and filling redundant forms to simply sending an SMS. At university, it reduced error-prone paperwork from 30 days to less than a second.
  • As our work reduced carbon emissions, our project was inaugurated by the prime minister of Bangladesh herself. It revolutionized admission processing in the entire country as all the universities followed our model later.
