Hi, I'm NILLAL

Computer Science Student • Systems & Algorithms • Software Development

Building things from scratch, breaking them, figuring out why they broke, and occasionally making them work.

GitHub LeetCode Codeforces

🔭 What I'm working on

  • ShopSphere — a mobile-first POS, billing and inventory management system built with Flutter, FastAPI and PostgreSQL, with JWT authentication and a REST API.
  • Rubik's Cube Solver — a C++ implementation of Kociemba's two-phase algorithm using IDA*, pruning tables and cubie-level representations.
  • TRM-Chess — a planned experimental chess engine exploring Tiny Recursive Models (TRMs) for recursive position evaluation and move selection, potentially combined with MCTS.
  • Exploring backend architecture, databases, algorithms and machine learning while building projects that force me to understand what's happening underneath the abstractions.

🧰 Tech I reach for

C++ Python Java Dart Flutter FastAPI PostgreSQL Git Linux

🚀 Featured projects

Project What it does
Rubik's Cube Solver C++ Rubik's Cube solver based on Kociemba's Two-Phase Algorithm — cubie representation, IDA* search, pruning tables, heuristic-guided search and an interactive ncurses input interface
ShopSphere Mobile-first POS and shop management system — Flutter frontend communicating with a FastAPI backend backed by PostgreSQL, with JWT authentication and REST APIs
TRM-Chess 🚧 Planned experimental chess engine based on Tiny Recursive Models — exploring recursive neural reasoning, policy/value prediction and MCTS-based search
Maze Solver Experiments with maze generation, graph traversal and pathfinding algorithms, exploring how different search strategies behave across generated spaces
Machine Learning Projects Experiments and coursework involving machine learning fundamentals, mathematical implementations and model experimentation

📚 Currently learning

Going deeper into backend development, database systems, distributed application architecture and machine learning, while exploring the intersection of neural reasoning and classical search algorithms.

Still learning, still building, still occasionally wondering why the code worked yesterday.
