Cover image for Built a self-verifying RAG pipeline
Built a self-verifying RAG pipeline that refuses to hallucinate confidently — uses an independent reranker (not the generating LLM) to judge answer quality, requires 4-source consensus, and scales responses across a 5-tier confidence system down to hard refusal.

Cover image for Olepress — Premium Specialty Oil
Olepress — Premium Specialty Oil E-Commerce Brand (Solo-Built) Designed and built a full e-commerce platform and brand identity for Olepress, Egypt's first premium specialty oil house — solo, from brand concept to storefront to backend, launched to real customers. What I built: Full storefront with product catalog (12 specialty oils), discovery packs, and subscription flow Custom brand identity and premium dark/gold visual design — built product visuals with AI-assisted design tools since professional product photography wasn't available yet at launch Backend handling orders, inventory, and subscriptions Honest note: the site launched and took real orders, but the business itself didn't continue past its initial phase — this project shows the full build (design, frontend, backend, launch), not an ongoing operation.

Cover image for Solving the "Last Mile" in
Solving the "Last Mile" in Enterprise SaaS: My Native Multi-Tenancy Architecture 🚀 Hey everyone, After years of building Enterprise applications, I noticed a recurring bottleneck: we spend months just setting up the foundational plumbing (Data isolation, JWT, Billing, RTL support) before touching the actual business logic. To solve this for my own freelance projects and agency clients, I spent the last few months building a production-ready Enterprise Boilerplate. The Stack & Architecture: Backend: Java 25 & Spring Boot 4 Frontend: Angular 21 (Standalone components) Data Isolation: Native Hibernate Multi-tenancy (Strict schema/database separation per tenant) Localization: Dynamic RTL/LTR with bilingual JasperReports generation. I built this specifically to cut a 4-month MVP development cycle down to just 14 days without sacrificing bank-grade security. I’ll drop the link to the live demo in the comments if anyone wants to see the architecture in action. I’m curious to hear from other Fullstack Engineers here—how do you usually handle strict multi-tenancy in your freelance client projects? Do you build from scratch every time, or rely on specific patterns? Would love to discuss architecture and share insights!

Cover image for This application is a library
This application is a library application and consists of two parts: a librarian section and a regular user section. The librarian section is responsible for: 1- Adding books, classifying them, determining the number of available copies of each book, and displaying an image of the book. 2- Responding to messages from users. 3- Removing books when they are unavailable. 4- Controlling the quantity of each book available. The regular user can access the application and do the following: 1- Searching for books by name and classification. 2- Borrowing books and agreeing to return them after the specified loan period, or extending the loan period. 3- Viewing the history of previous borrowings. 4- Sending messages to the librarian section and viewing previous questions and answers. 5- If borrowed books are not returned on time, the system will impose a late fee and suspend the user's borrowing privileges until payment is received. Users can pay through the application using bank cards.
