Short, sharp, and powerful.

scroll to explore

Architecture & System Design

System Architecture — I design the “skeleton” of your product — the part nobody sees but everyone depends on. Clean, scalable, and built so future developers don’t cry when they open the repo.

API Architecture — Think of APIs as the highways of your system. I make sure they’re fast, organized, and not the chaotic kind where you miss the exit and end up in another city.

Database Schema Design — Your data deserves a home that’s tidy, structured, and not a digital junk drawer. I design schemas that make sense today and still make sense a year from now.

Clean Architecture — Layers, boundaries, separation… basically the “Marie Kondo” of software. Everything in its place, everything with a purpose.

Data Modeling — Turning messy real-world information into neat digital shapes your system can actually understand. Like translating chaos into logic.

Authentication & Authorization Flows — Who can enter? What can they touch? I build secure flows that keep the bad guys out and let the right people in — without making them solve a puzzle every login.

Scalability Planning — Your system shouldn’t panic when your user base grows. I plan ahead so your app handles growth like a champ, not like a server having a meltdown.

MVC / MVVM / Modular Design — Fancy acronyms that basically mean: I write code that’s organized, predictable, and doesn’t collapse when you add new features.

🧠 Project Delivery, Business & System Thinking

Requirements Engineering — You tell me the idea — even if it’s vague — and I turn it into clear, actionable requirements. No guessing, no confusion, no “what did we mean by this?” moments.

System Structuring — I organize the entire project so everything connects logically. Think of it as building a digital city with roads that actually make sense.

Workflow Design — I map out how users move through your product. Smooth, intuitive, and without any “wait… what do I click now?” moments.

MVP Planning — I help you launch the smartest version of your product — not the biggest, not the smallest, but the one that gets you results fast.

Product Thinking — I don’t just build features. I build solutions that make sense for your business, your users, and your long-term goals.

Technical Documentation — Clear, human-friendly documentation that future developers will thank you for. No cryptic notes or missing steps.

Client Communication — I translate tech into human language. No jargon storms. No confusion. Just clarity.

🎨 Frontend Engineering (Advanced)

Component-Based Architecture — I build UI like Lego — reusable pieces that fit together perfectly and make your product easy to maintain.

State Management (Context API) — I keep your app’s brain organized so it always knows what’s happening. No memory lapses, no weird glitches.

UI Animation (Framer Motion) — Smooth, cinematic animations that make your interface feel alive — not like a PowerPoint slide.

Responsive Layout Engineering — Your product looks great on every screen: laptop, phone, tablet, fridge (if it has a browser).

Reusable UI Components — Buttons, cards, modals — built once, used everywhere. Clean, consistent, and efficient.

Accessibility-Friendly UI — I make sure everyone can use your product comfortably — because good design includes everyone.

🛠️ Backend Logic & Data Handling

Secure Authentication Systems — I build login systems that are safe, fast, and user-friendly. No complicated rituals required.

Role-Based Access Control (RBAC) — Admins get admin powers. Users get user powers. Nobody gets accidental superpowers.

CRUD Operations — The essential “create, read, update, delete” backbone of every app — implemented cleanly and reliably.

Data Validation & Sanitization — I make sure your system only accepts clean, safe data. No weird inputs. No surprises.

Error Handling Architecture — Errors happen — but they shouldn’t break your app. I build systems that catch issues gracefully and explain what went wrong.

API Integration & Consumption — I connect your app to external services smoothly, without breaking anything or causing digital drama.

🤖 AI Integration & Intelligent Systems

AI-Powered Features — I integrate AI where it actually helps — not just because it’s trendy. If it adds value, it goes in. If not, it stays out.

Prompt Engineering — Crafting precise instructions that make AI behave, respond accurately, and not hallucinate its way into chaos.

AI-Driven Personalization — Smart experiences that adapt to users — recommendations, insights, and tailored interactions.

LLM-Based Tools & Assistants — Building assistants that help users do more with less effort. Think of them as tiny digital coworkers.

AI Workflow Automation — Automating repetitive tasks so your team can focus on the important stuff — and your product feels smarter.

Data-Enhanced AI Decisions — Using real data to make AI outputs more accurate, reliable, and aligned with your product’s goals.

Avianta

Private charter and premium commercial flight search, united in one place.

Avianta began with a simple question — why is searching for private jets still so fragmented, slow, and unclear? Every operator had its own website, every broker its own system. The answer is a single, elegant search engine that brings private charters and premium commercial flights together with real-time data and a luxury aviation feel.

Overview

The frontend — React, Vite, TypeScript, and Tailwind — carries a clean luxury aviation aesthetic: dark gradients, gold accents, and smooth motion that matches the world of private travel. A lightweight Node.js + Express backend connects to RapidAPI’s Skyscanner endpoints and delivers normalized, real-time flight data. Vercel hosts the frontend, Railway powers the backend, and together they form a seamless, production-ready pipeline.

The Challenge

RapidAPI’s rate limits demanded careful fallback logic and smart response shaping to keep the experience smooth. Airport inputs had to be validated and normalized, because users type city names instead of IATA codes. The luxury UI had to stay consistent across laptop, tablet, and mobile — every gradient, shadow, and motion intentional — while CORS, environment variables, and production API stability all needed solving.

The Solution

One-way, roundtrip, and multi-city searches return results that feel like products: aircraft category, seat count, range, operator, availability window, and indicative pricing. A compact mobile card layout keeps browsing effortless on small screens. Fast, elegant, and ready to evolve — a clear proof of concept for investors, operators, and premium travelers who want clarity in a space that rarely offers it.

02 Research Platform

NAMA

A mental-health platform built for PhD research, in two versions of one identity.

Student evaluations, profiles, dashboards, and structured psychological data collection — a complete mental-health management platform built for a PhD research project, with an exhibition version for conferences and a secure production version for real use.

Overview

Two deployments of one identity. The Exhibition Version is a visually polished, frontend-only build for academic presentations and conferences, running on mock data to demonstrate the full flow without exposing any real student information. The Production Version is the real-world implementation: Firebase Authentication, Firestore real-time data, protected dashboards, and role-based access for students, counselors, and parents.

The Challenge

One system had to serve two completely different deployment contexts while keeping identical UI and user flow. The exhibition build had to look fully functional using mock data, and the production build required real authentication, encrypted data storage, and role-based access controls — without the two ever drifting apart.

The Solution

A dual-version architecture sharing the same React codebase, switched by environment-based feature flags. Exhibition mode runs realistic mock data with believable loading states for conference demos; production mode integrates Firebase Authentication, Firestore, and role-based routing. Structured psychological data models were designed in collaboration with the PhD researcher to capture every required metric and evaluation criterion.

03 AI Product

Kevo

An AI career-analysis engine that turns self-understanding into direction.

Raw inputs become a complete professional profile — personality, cognitive style, and the career paths that fit, explained rather than guessed. AI reasoning made personal.

Overview

Kevo transforms raw user inputs into a complete professional profile and delivers personalized, data-driven career recommendations. It helps users analyze their personality and cognitive style, discover career paths that match their strengths, and understand why certain roles fit them better — making AI guidance accessible and meaningful for students, professionals, and career changers.

The Challenge

Building an AI reasoning engine that felt intelligent and personalized — not like a generic quiz — required careful prompt engineering and structured output parsing. Input validation, rate limiting, and a secure contact system were also required to make the platform production-ready.

The Solution

React + Vite for fast performance, Framer Motion for cinematic animation, and TailwindCSS for clean styling. Structured prompts analyze user inputs and generate detailed career recommendations with explanations, while a secure Nodemailer contact system — protected by rate limiting and input validation — lets companies reach out directly. Intelligence, turned into action.

04 Brand & Web

Gym Website

A bold, culturally aligned fitness landing page for the Lebanese market.

Most local gyms have no real online presence. This concept site gives one a strong brand, clean UI, and smooth motion with a heartbeat that feels like home.

Overview

A modern fitness landing page designed specifically for the Lebanese / Baalbek market — bold, energetic, and culturally aligned with the identity of local gym owners. The goal was a concept website that demonstrates strong branding, clean UI/UX, smooth animations, and a theme inspired by local fitness culture.

The Challenge

The design had to feel globally modern and locally relevant at once — meeting contemporary web standards for animation, responsiveness, and branding, while still appealing to gym owners who may never have had a digital presence before.

The Solution

A fully responsive React website: hero with strong branding, class categories, trainers, pricing plans, contact, and smooth scroll animations. Bold typography and energetic gradients carry gym culture while keeping professional polish — commercial-ready branding and UI/UX direction for a specific audience.

05 Backend Engineering

Habit Tracker

A clean-architecture CLI habit tracker with real backend thinking.

Habits, streaks, and progress analytics with zero UI framework — just disciplined architecture and functional programming behind a terminal.

Overview

A fully structured command-line habit tracking system built in Python. The focus is clean architecture, functional programming, and reproducible behavior — a strong demonstration of backend logic and software design principles, managing habits, tracking progress, and analyzing streaks without any UI framework.

The Challenge

Most habit-tracking tools are visual and heavy. This one had to be lightweight and architecture-driven — every feature implemented through disciplined terminal I/O with robust data handling underneath.

The Solution

Clean architecture separating concerns into distinct layers, functional programming for predictable, testable behavior, habit creation with configurable periods, check-in tracking with streak calculation, progress analytics, and persistent SQLite storage. Real logic, not just interfaces.

06 AI · Data Platform

Dashboard

AI-powered predictive maintenance for real-time industrial monitoring.

2000+ sensor readings, three AI providers, and one dashboard that tells you what will fail — before it does.

Overview

A full-stack predictive maintenance platform that monitors industrial machines, detects anomalies, and predicts failures from real-time sensor data. Mock sensor data — 2000+ readings across temperature, vibration, pressure, humidity, operating hours, and load — simulates realistic industrial IoT and can be replaced with live data from any company.

The Challenge

Simulating realistic industrial IoT data while classifying machine status into ok, warning, and critical thresholds; orchestrating Gemini, DeepSeek, and Groq with careful fallback handling; and triggering alerts the moment failure probability passes 0.7 — all behind a security-hardened backend with Helmet, CORS, rate limiting, and input validation.

The Solution

A RandomForestClassifier with 200 estimators and IsolationForest anomaly detection, served through a Node.js + Express API with cached lookups. A React + Tailwind + Framer Motion frontend with lazy loading and code splitting, Supabase storage, SendGrid alerting, and a containerized AI service running Gunicorn with 4 Uvicorn workers — deployed on Railway and Vercel.

3D Portfolio

A cinematic 3D hero, rebuilt to perfection.

A floating 3D portrait that never clips, duplicates, or misaligns — on any device, at any width.

Overview

A complete rebuild of a 3D-driven hero section designed to deliver a cinematic first impression through precise alignment, responsive behavior, and a clean visual hierarchy — a centered, single-line heading paired with a floating 3D portrait that remains fully visible, never clipped, duplicated, or misaligned across devices.

The Challenge

Preventing text wrapping on large screens, maintaining consistent spacing, and making the 3D portrait adapt smoothly without breaking the theme or color system at every viewport size.

The Solution

Precise CSS and component architecture. Every breakpoint was tested and tuned, the 3D integration carefully aligned, and the color system enforced consistently — a pixel-perfect, production-ready interface that preserves the cinematic original while demonstrating strong debugging, design-system enforcement, and responsive skills.
