H.M. Tajul Islam Tanim

I'm a Physics undergraduate at the University of Rajshahi, Bangladesh, working at the intersection of physics, mathematics, and computing.

Rather than learning technologies only through tutorials, I prefer building things from the ground up - from numerical solvers and multi-node computing clusters to production web applications and self-hosted infrastructure.

Currently exploring:

• Scientific computing & numerical methods
• High-performance and parallel computing
• Systems programming
• Full-stack application architecture
• Self-hosted infrastructure & DevOps
• Machine learning
• Mathematical modeling and computational physics

For more go to this section.

My physics background naturally pulled me toward computational methods.

Scientific Computing Numerical methods for mathematical and physical problems - with a particular interest in ODE systems, numerical integration, optimization, and computational modeling.

High-Performance Computing Experimenting with building and managing a small multi-node HPC environment, with a long-term goal of scaling computational physics problems across multiple CPU cores and machines.

A small programming language ecosystem built from scratch in C++, with its own interpreter, formatter, tooling, and editor integration.

Focus: language design · parsing · interpreters · developer tooling

I'm especially drawn to the overlap of these areas - using low-level, high-performance computing ideas to solve real scientific and engineering problems.

Learn the theory. Build the system. Measure the result.

I like understanding what's happening underneath the abstraction - whether that's a numerical algorithm, a database query, a network request, or a CPU instruction.
