Engineering at
every layer

Formed at 42 School — where the curriculum has no teachers, no textbooks and no shortcuts — I learned to engineer solutions through iteration, peer review and relentless debugging.

My foundation lives in systems programming: pointers, memory arenas, POSIX APIs, concurrency primitives. From there I built upwards into full-stack web, mobile and now Data Science and ML.

I approach every problem the same way — understand the machine, understand the math, write code that respects both.

⚙
Low-Level First
Comfortable below the abstraction layer — memory, file descriptors, system calls and raw sockets.
◈
Algorithm-Driven
Graph traversal, complexity analysis, data structure design — every solution gets the right algorithmic treatment.
⬡
Full-Stack Capable
From Spring Boot APIs to Next.js frontends, Docker orchestration and Redis caching.
◎
AI / ML Trajectory
Expanding into data science, ML pipelines and intelligent systems — backed by strong mathematical fundamentals.

Cube3D

C

Raycasting Graphics Engine

+
CMiniLibXGraphics MathRaycasting

A pseudo-3D raycasting engine inspired by Wolfenstein 3D, built from scratch in C. Implements full scene rendering, textured walls, a minimap system, player movement and mouse rotation — zero external graphics libraries beyond MiniLibX.

  • ▸Pseudo-3D rendering via DDA raycasting algorithm
  • ▸Custom .cub map file parser
  • ▸Dynamic minimap with player FOV indicator
  • ▸Mouse-based camera rotation & smooth movement
  • ▸Texture mapping on wall faces
⬡

TCP Chat Server

C

Multi-Client Real-Time Networking

+
CSocketsselect()UnixConcurrency

A production-grade multi-client TCP chat server using raw POSIX sockets and I/O multiplexing via select(). Manages concurrent clients, broadcasts messages, and handles file descriptor lifecycle — no threads, no external libs.

  • ▸Non-blocking I/O multiplexing with select()
  • ▸Dynamic client registration & disconnect cleanup
  • ▸Real-time message broadcast to all peers
  • ▸Robust file descriptor management
  • ▸Bare POSIX — no frameworks or abstractions

ft_transcendence

TS/Java

Full-Stack Web Application

+
Next.jsSpring BootDockerRedisMySQL

A modern fullstack web application built as a team project. Features JWT authentication, real-time client-server communication, containerised microservices and a polished Next.js frontend backed by a Spring Boot REST API.

  • ▸Next.js frontend with TailwindCSS
  • ▸Spring Boot REST API backend
  • ▸Docker Compose for full stack orchestration
  • ▸Redis session caching layer
  • ▸MySQL persistent data store

Social Network Simulator

C++

Graph-Based Data Structures

+
C++GraphsBFSDFSAlgorithms

An academic simulation of a social network modelled as an undirected weighted graph. Implements friend suggestion via BFS, mutual-friend detection, connected components analysis via DFS, and adjacency-list storage.

  • ▸Adjacency-list graph with O(V+E) traversals
  • ▸BFS-based friend-of-friend recommendation
  • ▸DFS connected-component discovery
  • ▸Mutual friendship intersection in O(d) time
  • ▸Serialisable node/edge schema

Gamified Quiz App

JS

Cross-Platform Mobile

+
React NativeJavaScriptGamificationMobile

A mobile quiz application built with React Native. Features dynamic question banks, a points and streak system, animated feedback transitions and a leaderboard — deployed on both iOS and Android.

  • ▸React Native cross-platform build
  • ▸Score, streak & XP gamification loop
  • ▸Animated correct/wrong feedback
  • ▸Modular question bank architecture
  • ▸Responsive mobile-first UI
