Work Experience
A chronological timeline of production engineering, SaaS architectures, and high-impact web applications built across remote & cross-functional teams.
Developed and shipped Sawt AI, an AI-powered survey SaaS for the Saudi market with bilingual Arabic/English support and RTL-first UX. Built full-stack features using React.js, Next.js, Node.js, Express.js, and TypeScript, integrating REST APIs and production workflows.
- Integrated multiple AI providers (GPT, Gemini, Grok, Perplexity) with robust response validation workflows for consistent, brand-safe outputs.
- Implemented MyFatoorah subscription billing, tier-based access control, API usage tracking, webhooks, analytics, and automated email workflows.
- Built secure backend systems including role-based authentication, rate limiting, audit logging, and bot protection; contributed full-stack CRM with Socket.IO real-time workflows, SLA tracking, and pipelines.
- Developed React Native features and contributed to Thaddi, an Arabic-first football prediction platform, including mobile/web product development and release workflows.
Solely owned the frontend of a multi-role healthcare SaaS (Super Admin, Doctor, Patient, Clinic), covering UI design, development, and user testing without designer or QA support.
- Built 3 role-based login flows with secure authentication and 10+ CRUD modules including patient management, appointment scheduling, clinic records, and admin controls.
- Developed data-rich dashboards with reactive filters, charts, and exportable reports; integrated Node.js/MongoDB REST APIs across all roles.
- Delivered end-to-end user experience autonomously from zero to production deployment.
Built and customized Moodle-based LMS frontends for educational institutions; developed responsive dashboards and reusable React.js components for student, teacher, and administrator workflows.
- Created academic management modules for attendance, assessments, course management, and reporting.
- Integrated REST APIs and optimized frontend performance through code splitting and lazy loading.
- Standardized component patterns across student and administrative dashboards.
Built the full frontend of Breeze SaaS using Next.js (SSR/SSG) + TypeScript; integrated REST APIs and GraphQL CMS queries with Sanity.io, Contentful, and Strapi.
- Optimized Core Web Vitals (LCP, CLS, FID, TTFB) through image optimization, code splitting, and caching.
- Achieved a 50% improvement in page load speed and a 20% boost in user engagement across production web applications.
- Architected clean headless CMS query pipelines for dynamic content publishing.

LLMs, Pipelines & WorkflowDevelopment Process
How I take complex product concepts from initial scoping to high-performance production builds.
Scope & Strategy
We define core user personas, map key workflows, specify features, and lay out the exact product roadmap to maximize initial market launch speed.
System Architecture
Designing secure database models (relational/document), structuring API routes, and establishing robust role-based authentication schemes.
Full-Stack Development
Coding pixel-perfect React/Next.js interfaces, implementing clean modular layouts, and programming fast server endpoints in Node.js.
Cognitive AI Integration
Connecting language models, creating fallback routing models, programming conversational RTL layouts, and structuring qualitative RAG flows.
Core Web Vitals Tuning
Benchmarking performance with Lighthouse, optimizing image loading, compiling statically where possible, and tuning API responses under 100ms.
Deployment & Launch
Configuring containerized pipelines, launching on CDN edges, and setting up error reporting dashboards for seamless hands-off operations.
Zero Handoff Friction
I handle both high-end UX design and backend architectures directly, meaning features ship faster without team translation delays.
Direct Collaboration
No account managers or middle project coordinators. You interface directly with the systems engineer crafting your product.
Enterprise Engineering
Every module is engineered with robust typescript types, complete separation of concerns, and clean architectural design patterns.
Technical Blog
Writing about modern software engineering, API designs, and full-stack best practices.
