A music management and streaming backend with in-memory transcoding written in Rust

• Build with performance in mind while keeping memory safety thanks to Rust.
• Automated pipeline to build Docker image and binaries for MacOS, Linux, FreeBSD and Windows.
• Integrate directly ffmpeg C api for fast in-memory transcoding with no temporary file required.
• Maintain strict code quality with clippy pedantic profile and 80% code coverage.
• Integrate S3-compatible storages support streaming from cloud storage.

A docker compose/docker swarm reimplementation with IaC philosophy.

• Build with Python and Pulumi to leverage the consistency and reproducibility of IaC with the flexibility of Python.
• Provide alternatives for popular cloud services: Google Meet, Google Drive/Icloud, Spotify, Netflix, Google Photo/Icloud Photo, Notion, Apple Home and much more.
• Integrate traefik as reverse proxy with DDOS and bot protection via Crowdsec.
• Remotely access for private routes via Wireguard-based VPN Tailscale.
• Integrate barman for point-in-time database backup and restic for file-based backup to offsite cloud storage.
• Full-featured monitoring solutions with OpenObserve and Grafana.
• Multi-hosts support and custom config format for full-featured service declaration.

Cloud filesystem plugins for "Modular Filesystems C API" RFC.

• Extracted the current filesystem (S3, GCS, Apache Hadoop) implementations from TensorFlow Core to modular plugins.
• Added filesystem supports for Windows (previously only on MacOS and Linux).
• Gained experience on teamwork and the way of working in big open-source software project.

Utility for managing dotfiles (config/shell/environment variable) written in Rust.

• Git-based approach enables easy backups and rollbacks any configuration.
• Ensuring consistency and ease of deployment across different systems or setups

GRPC support for interacting with Google Cloud Storage (GCS) in google-cloud-cpp.

• Built a GCS emulator with support for both REST and GRPC endpoints using Flask.
• Added client functions for GCS gRPC endpoints.

Real-time video game character replacement without modding the game source code.

• Tuned pose-detection algorithm with NVIDIA TensorRT.
• Developed a pipeline intergrating pose-detection and apperance replacement with OpenCV and PyTorch.

Ruin probability of an insurance company.

• Studied include the Lundberg coefficient, the net profit condition, and the majoration of the ruin probability based on the Cramér-Lundberg model.
• Done extensive numerical experiments to verify the majoration of the ruin probability.

Image restoration with randomly-initialized convolutional neural network.

• Explored the idea behinds the paper "Deep Image Prior".
• Studied the effect of network architecture for multilple image restoration tasks.

Descriptive analysis of Spotify database using R.

• Performed comprehensive data analysis including univariate, bivariate, and Principal Component Analysis (PCA).
• Utilized R tidyverse for data engineering and manipulation.
• Designed and generated detailed visualizations using the ggplot2 package.
