Current Projects

These are things I’m actively playing around with (maybe once a week or once every 6 months).

CICFlowMeter API

Tech Stack: Python • FastAPI • Docker

Project Link: https://github.com/thisizaro/cicflowmeter-docker-api

Blog: CICFlowMeter API (Dockerized)

Built a Dockerized REST API to process uploaded PCAP files using CICFlowMeter and return extracted network flow features as CSV files.
Orchestrated execution of Java/Gradle-based CICFlowMeter from a FastAPI service, isolating heavy dependencies from the API layer.
Implemented file handling, ZIP packaging, and controlled single-request execution to support large PCAP analysis workloads.
Exposed interactive API documentation using Swagger UI for easy testing and integration.
Technologies: Python, FastAPI, Docker, Java, Gradle, CICFlowMeter, PCAP, REST API

Tech Stack: Python • FastAPI • Cryptography

Project Link: https://github.com/thisizaro/safeshare_backend

Blog: Safeshare explained

Developing a secure file-sharing service using FastAPI, implementing JWT (JSON Web Tokens) for stateless authentication and Bcrypt for secure password hashing.
Authored comprehensive technical documentation including SRS, System Architecture, and Testing Plans, following industry-standard SDLC practices.
Designed a Role-Based Access Control (RBAC) system and middleware to protect sensitive API endpoints.
Technologies: Python, FastAPI, JWT, Bcrypt, Docker, Swagger/OpenAPI

Tech Stack: Chrome Extension • JavaScript

Project Link: https://github.com/thisizaro/KataYomi

Blog:

Building a lightweight Chrome extension (Manifest V3) to assist Japanese learners by displaying Hiragana readings for Katakana text on hover.
Implemented client-side Katakana detection by traversing DOM text nodes and matching specific Unicode ranges (U+30A0–U+30FF).
Developed a custom translation logic using Unicode offset mapping for fast, dictionary-free conversion.
Designed a non-intrusive tooltip overlay to display readings without disrupting original page layout.
Technologies: JavaScript, Chrome Extension API, DOM Manipulation, Unicode Processing

Tech Stack: C • Linux Kernel • IPC

Blog:

Built a Linux kernel module enabling multi-client terminal-based chat via a custom character device (/dev/kerneltalk).
Implemented producer–consumer synchronization using a circular buffer to safely handle concurrent operations.
Designed blocking and non-blocking I/O behavior to manage message flow across multiple user-space processes.
Enabled kernel–user space communication using file operations (open, read, write) in C.
Technologies: C, Linux Kernel, IPC, Character Device Drivers
