You will get optimized SQL And database design and Transaction-SQL query tuning
Rising Talent
Project details
A slow database or poorly structured schema bottlenecks your entire application. I provide professional Microsoft SQL Server database design, relational schema modeling, and advanced T-SQL query performance tuning to ensure your data layer runs fast, scales cleanly, and stays secure.
What I deliver:
• Normalized Schema Design: Scalable relational architectures (OLTP) with robust Primary/Foreign keys, constraints, and audit logging.
• T-SQL & Query Optimization: Refactoring slow queries and stored procedures, analyzing execution plans, and fixing indexing bottlenecks (Index Tuning).
• Multi-Tenant Architectures: Multi-tenant schema design with data isolation patterns and Row-Level Security (RLS).
• Visual ERD & DDL Scripts: Complete Entity-Relationship Diagrams and production-ready, clean SQL migration scripts.
Whether you are architecting a database from scratch for a SaaS startup or fixing critical performance issues on a live system, you will receive clean, enterprise-grade database engineering.

Need Usability Testing for Web / Mobile Application
Love working Joudi! Very professional, detail oriented, with excellent follow through. Ultimately, he simply does what he says he's going to do.
About Joudi
.NET Backend Engineer & Application Security Specialist | ASP.NET Core
Abu Dhabi, United Arab Emirates - 7:47 am local time
I specialize in building production-ready ASP.NET Core web architectures, robust SQL Server databases, and enterprise-grade security layers. To give my clients unmatched delivery speed, I leverage my proprietary CLI scaffolding engine (+10,000 lines of custom C#) that translates database schemas into clean, SOLID-compliant layered architectures in seconds.
With a background in cybersecurity, I don't just build APIs that work—I build APIs that withstand real-world threats by mitigating broken access controls (BOLA/IDOR) and enforcing strict data contracts.
⚡ WHAT I DELIVER TO YOUR SYSTEM:
• High-Performance ASP.NET Core Web APIs: Modular, scalable, and fully documented via Scalar UI / Swagger.
• Bulletproof Database Architecture: Optimized T-SQL Stored Procedures, ACID-compliant transactions, indexing, and multi-tenant row-level isolation.
• Security-First Authentication: JWT tokens, role/policy-based authorization, dynamic salting, and cryptographic password hashing (PBKDF2/SHA256).
• Frontend-Ready Contracts: Clean, filtered DTOs and auto-generated TypeScript Axios clients for zero-friction frontend integration.
• Production DevOps: Multi-stage Docker packaging, docker-compose, and GitHub Actions CI/CD automation.
🛠 CORE TECH STACK:
• Languages & Frameworks:
Backend: C#, ASP.NET Core, .NET 8/10, SQL & Relational Databases,
Frontend: HTML & CSS & JS & Typescript & React Vite.
• Databases: MS SQL Server, PostgreSQL, MySQL, MariaDB, Oracle
• Architecture & Patterns: N-Tier, Clean Architecture, Repository, Unit of Work, Factory, Strategy, Facade, Dependency Injection
Based in Abu Dhabi (Golden Visa Holder), available for instant onboarding on fixed-price deliverables or hourly contracts aligned with US & EU time zones.

Steps for completing your project
After purchasing the project, send requirements so Joudi can start the project.
Delivery time starts when Joudi receives requirements from you.
Joudi works on your project following the steps below.
Revisions may occur after the delivery date.
1. Requirement Analysis & Discovery
I analyze your business domain, existing database schema, or slow T-SQL queries to map relational dependencies and identify performance bottlenecks.
2. Schema Architecture & Query Optimization
I architect the normalized schema, implement proper indexes/constraints, or refactor T-SQL queries and stored procedures for optimal execution.
