Ported a C# AutoCAD plugin to a LibreCAD plugin for ATR/BPN (Agrarian and Spatial Planning Ministry of Indonesia), using C++ with the QT Framework and SQLite.

Led the development of a high-performance audio analysis core module for various applications (SaaS, Desktop App, SDKs), reducing code redundancy by designing different interfaces with the same core module. Utilized C++17, Go, and PostgreSQL, and implemented cross-platform compatibility for Linux and Windows. Also contributed to various web development projects by utilising Python, Go, .NET Framework, React, Node.js, Docker, and Microsoft SQL Server.

Maintained and developed high-performance audio analysis SDKs written in C++17.

Developed a novel approximate similarity search algorithm named Variance-Aware Quantization using C++11, Intel SIMD intrinsic, and the Eigen Library. Additionally, designed and implemented a bit-vector-based approximate k-NN library for high-dimensional data using C++11. My contribution involves studying the parallel database migration behavior with different DBMS (PostgreSQL, SciDB) and various data formats (Apache Arrow, ZeroMQ).

Assisted students in Programming Fundamentals, Algorithm and Data Structures, and Object-Oriented Programming practical classes with personalised guidance and feedback, resulting in an enhanced understanding of programming concepts.

Built dynamic and responsive websites for a variety of corporate clients using JavaScript web development stacks: NodeJS, React, and MongoDB.
