Hey there 👋
I’m Ragib Hasan — a systems engineer and AI builder from Bangladesh. I’ve been writing code since 2021, mostly working close to the metal with Rust, C, and Python.
What I Do
I’m co-founder at CholoKLabs, where we’re building AI-powered tools and infrastructure. My work focuses on systems design, model deployment, and performance engineering in a fast-moving early-stage environment.
Before that, I spent years on independent research and projects — systems programming, AI/ML research, and competitive programming. I’ve built inference engines, monitoring tools, MCQ exam platforms, and fine-tuned language models.
Technical Focus
Languages: Rust · C · C++ · Python · Go · Java · SQL · Assembly x86 · Bash
Systems & Infrastructure: Linux (Arch) · Ubuntu · VPS Administration · Docker · Shell Scripting · AVX2 SIMD
AI/ML: NumPy · Pandas · Matplotlib · Seaborn · ML Training · Hugging Face · LoRA/QLoRA · OpenCV
Other: Git · Laravel · WordPress · Competitive Programming
Projects
Some things I’ve built:
- linfer — Rust-based local LLM inference engine with custom
.lnfbundle format, AVX2 kernels, and 3x faster performance than comparable solutions - ExamCore — Laravel 11 MCQ exam platform with multi-role support, immutable answer locking, and bulk import/export
- nexa — Diffusion-based computer vision pipeline for image generation and processing
- SysWatch — Bash CLI system monitor using
/procfilesystem with CPU/RAM alerts and log rotation - Face Recognition Attendance — Automated attendance system with real-time facial detection
- LLaMA2 Fine-Tuning — Domain-specific fine-tuning using LoRA/QLoRA for parameter-efficient adaptation
Competitive Programming
I’ve solved 200+ problems across multiple platforms:
- Codeforces — @rhasan
- LeetCode — @ragibhasan
- CodeChef — @ragib5303721
- Toph — @ragibmondal
- AtCoder — @ragibhasan
AI/ML Profiles
