Preplify: AI Interview Prep

Preplify: AI Interview Prep

FEATURED

A production-grade, cloud-native AI interview preparation platform built on Next.js and TypeScript, designed to serve thousands of concurrent users with real-time, personalized interview experiences. The platform integrates multiple LLM providers (OpenAI and Gemini) through a unified orchestration layer, combining GraphQL for complex data relationships with REST endpoints for high-throughput AI workflows. Deployed via Docker-based CI/CD pipelines with GitHub Actions on scalable AWS infrastructure, the system features WebSocket-driven real-time communication, Zustand-powered state management for multi-step interview flows, and a mature component library that accelerates frontend feature delivery.

Service Management Platform

Service Management Platform

FEATURED

An enterprise-scale Micro Frontend (MFE) platform for Universal Weather and Aviation, enabling distributed engineering teams to independently build, test, and deploy domain-specific features within a unified shell architecture. The platform integrates real-time aviation service workflows via Sabre REST and GraphQL APIs through Apollo Client, built on a Monorepo foundation with Webpack Module Federation for runtime module composition. The shell application orchestrates routing, authentication, shared state (Redux Toolkit), and a 50+ component design system with WCAG/AODA compliance, supporting five independent teams shipping to production simultaneously through feature-flagged CI/CD pipelines.

Cyber Mart

FEATURED

A full-stack multi-vendor e-commerce marketplace built on Next.js and Node.js/Express.js, delivering high-performance shopping experiences through strategic server-side rendering, optimized MySQL schemas, and cloud-hosted CI/CD deployment pipelines. The platform supports thousands of product listings across multiple vendors, integrating third-party payment processors and inventory providers via versioned REST APIs. A polyglot data architecture combines MySQL for transactional integrity (orders, inventory) with MongoDB for flexible content storage (product descriptions, vendor profiles), deployed on AWS with Docker-based containerization.

Chalet Retreat

FEATURED

A luxury vacation rental platform built with Next.js and TypeScript, featuring interactive map-based property discovery powered by Google Maps API with custom clustering for thousands of listings. The platform delivers premium, image-rich experiences through aggressive media optimization (lazy loading, responsive images, CDN-backed caching) while maintaining sub-2-second load times. A multi-step Stripe-integrated booking flow handles high-value transactions with robust validation and progressive disclosure, and the entire frontend is backed by a Material UI + SASS design system tuned for the visual standards of luxury hospitality.

Class Ops

A full-stack classroom management platform built to demonstrate enterprise-grade Next.js + NestJS integration with modern TypeScript tooling. The system simulates academic operations for a multi-department institution with 500+ student records, 50+ courses, and 20+ faculty assignments, featuring a server-side rendered Next.js frontend with optimized data fetching backed by a scalable NestJS API using Drizzle ORM and Neon PostgreSQL. The platform showcases role-based access control, real-time dashboards with incremental static regeneration, optimized database queries, and a production-ready CI/CD pipeline with Docker containerization and GitHub Actions automation.

OOGO

FEATURED

A multi-vendor e-commerce marketplace custom-engineered for the UAE market, featuring fully bidirectional Arabic/English experiences with structural RTL layout support, regional payment gateway integration alongside Stripe, and three interconnected portals (Customer, Vendor, Admin) sharing a unified Redux state layer. The platform handles the unique complexity of bilingual commerce—where layout direction, typography, iconography, and interaction patterns must invert completely for Arabic users—while serving a mobile-first audience through a modular React architecture with location-aware vendor discovery via Google Maps API.

Coffee Tea

FEATURED

A virtual interview preparation platform built with Next.js and TypeScript, combining real-time peer-to-peer video sessions via WebRTC with Firebase-powered mentor matching, Stripe-integrated booking and payment flows, and structured feedback dashboards. The platform uses Firebase (Firestore and Cloud Functions) as its real-time backbone—handling WebRTC signaling, mentor availability state, session coordination, and post-session feedback collection—while the Next.js frontend delivers a polished, anxiety-reducing coaching experience with Framer Motion animations and Tailwind CSS design optimized for the psychological demands of interview preparation.

Audits-IQ

FEATURED

A mobile-first enterprise auditing and inspections platform built with React Native and Firebase, designed for offline-first fieldwork in environments with intermittent or zero connectivity. The platform features a configurable drag-and-drop form engine with conditional logic and branching workflows that adapts to diverse industry inspection requirements without engineering changes. A local-first data architecture ensures inspectors can capture data, attach photos, and complete full audit workflows while completely offline, with conflict-aware synchronization that reconciles local changes with the central Firestore database when connectivity returns. Automated reporting services generate structured PDF and Excel outputs directly from audit data, eliminating manual post-inspection documentation.

Resume RAG Chatbot

Resume RAG Chatbot

FEATURED

An AI-powered portfolio assistant built into a Next.js site that answers visitor questions about Sadam's background using retrieval-augmented generation. The system parses resume content into semantic chunks, stores embeddings in PostgreSQL with pgvector, retrieves the most relevant context for each question, and streams grounded responses through the Vercel AI SDK. The implementation combines a polished chat widget, typed server routes, Gemini-powered embeddings and generation, and guardrails that keep responses tied to documented experience while still translating that experience into useful team and product outcomes.
