I'm Hadeel Sulieman — a full-stack web developer and computer scientist with 6+ years of shipping React, Next.js, NestJS and PHP applications, and 4+ years training young people to code in UNICEF-funded programs across North Lebanon.
I started building websites in 2019 and never stopped. Over the years I've worked across the whole stack — designing user-friendly front-ends, writing back-end services and APIs, wiring up databases and shipping mobile apps — for agencies, tech companies and freelance clients.
What makes my path a little different is the classroom. Since 2021 I've taught web and mobile development to hundreds of hours' worth of students, from 12-year-olds building their first app in MIT App Inventor to young adults learning React and Node in the UNICEF-funded BRAVE program. Teaching forces you to truly understand what you build — and to explain it clearly.
Today I'm a Data Entry Specialist at Croshina, finishing my Master's in Computer Science, and always looking for the next problem worth solving with code.
Seven years across development, instruction and freelance — from agency websites to microservice back-ends.
Since 2021 I've taught coding in refugee camps and learning centers across North Lebanon — turning curiosity into real, working projects.
Building Resilient and Vibrant Environment — a livelihood project in Badawi and Nahr El-Bared camps. I teach web and mobile development to youth aged 13–26 and design the curriculum they follow.
A technology and digital-skills track for girls and young women. Hands-on activities that build confidence, problem-solving and the belief that tech is theirs too.
Complete web development tracks at QUANTUM, Proof Center and DSC — plus private lessons in coding and robotics for students who want to go further.
A full-stack toolkit, from pixel to database — with a soft spot for React and NestJS.
Websites, mobile apps and robots — some for clients, some for classrooms, all built to work in the real world.
Front-end components in React and Next.js talking to NestJS microservices over REST — with auth, validation and DTOs — built during the NexRush internship.
Multiple Android apps built with Android Studio and MIT App Inventor — for freelance clients and as teaching projects that students then rebuild themselves.
A series of Arduino-based robots and microcontroller projects, from line-followers to sensor rigs — plus a private course teaching students to build and code their own.
Business and portfolio websites for freelance clients and agencies (PRO PRODUCTION, Al-Rinawi Tech) — custom PHP/JavaScript builds and WordPress sites, designed to be fast and user-friendly.
End-to-end MongoDB · Express · React · Node application built during the 3-month TECHLARIOUS program — REST API, auth and a responsive React front-end.
A complete beginner-to-React curriculum with projects, exercises and assessments, used to train youth in Badawi and Nahr El-Bared camps under the UNICEF-funded BRAVE program.
A strong academic base, kept sharp with continuous training.
M1 in progress — deepening knowledge in algorithms, systems and software engineering.
Programming, data structures, databases, web development and software engineering.
GPA 3.52 / 4.0Whether it's a web project, a teaching program or a full-time role — I'd love to hear about it.
