About

Professional summary

I am a lead software engineer and full-stack developer based in Tunis, Tunisia, with experience delivering more than 15 production platforms across healthcare, SaaS, travel, finance, legal technology, e-commerce, and education.

I lead engineering at Trends Digital, where I define technical strategy, select technology stacks, design APIs, review code, and mentor developers. I have architected multi-product systems including a dental-aligner ecosystem, cloud file-management platform, AI content SaaS, and digital training platforms.

I work across the entire product lifecycle, from product scoping and system architecture to frontend and backend implementation, cloud deployment, payment integration, and ongoing support. My core stack includes TypeScript, JavaScript, PHP, Python, React, Next.js, Node.js, Laravel, Flutter, and SQL and NoSQL databases.

I have extensive experience building real-time, multi-tenant, and secure systems. My work includes JWT token rotation, role-based access control, WebSockets, queue-based automation, subscription billing, marketplace workflows, document management, and AI-powered content and data-processing features.

As a co-founder and lead developer of BooknDish, I build subscription-based restaurant software for reservations, ordering, kitchen operations, inventory, staff scheduling, and multi-location management. I also run a freelance practice serving clients in aviation, finance, travel, legal technology, and e-commerce.

I enjoy leading technical delivery, solving complex product problems, and building scalable platforms that create measurable business impact. I am comfortable collaborating with multidisciplinary teams and translating business requirements into reliable, maintainable software.

Career history

Lead Engineer & IT Team Lead Trends Digital

I lead technical strategy, architecture decisions, sprint delivery, technology selection, API contract definition, pull-request reviews, and junior developer mentoring across the agency's client portfolio.

I architected and delivered RealSmile, a cross-platform dental-aligner ecosystem with a Next.js application, Node.js and Express API, Flutter patient application, 3D scan workflows, ordering, invoicing, chat, OTP authentication, and secure session management. I also delivered Oxfam's gender-equality training platform, a fertility-clinic platform for Clinique la Rose, and DataSafe, a cloud file-management and backup-monitoring product with multi-workspace access, granular sharing, automated jobs, and failure alerts.

Software Engineer (Capstone Project) Trends Digital

I built RevoluAI, a multi-tenant AI content SaaS offering customizable text generation, image and video editing, text-to-speech, and trainable custom chatbots. The product was delivered across 18 user stories in two Scrum sprints.

I also developed AiGraphy, a Flutter-based AI photo-editing application with face swapping, background removal, content moderation, and a token-based rewards model. I integrated subscriptions, token purchases, role-based workspaces, and an administrative dashboard for users, revenue, and API configuration.

Freelance Full-Stack Developer Freelance

I manage end-to-end product delivery for clients in finance, aviation, travel, legal technology, and e-commerce, covering discovery, architecture, development, deployment, and ongoing support.

My projects include CEOIT, an all-in-one CRM, HR, payroll, invoicing, and team-chat platform; SkyWings, a flight-school LMS optimization project; Compta-Air, a multilingual accounting SaaS; an automated Umrah visa workflow platform; Estateably's trust-and-estate platform; and B2B e-commerce and infrastructure marketplaces for DGTEC and IT-BAFA.

Co-Founder & Lead Developer BooknDish

I co-founded and developed a multi-tenant restaurant SaaS that generates recurring subscription revenue. The platform supports reservations, dynamic menus, live order routing, kitchen display workflows, inventory, staff scheduling, and multi-location management.

I designed a modular Laravel and Livewire architecture and integrated more than eight payment gateway options, including Stripe, PayPal, Mollie, and Paystack. The owner dashboard enables centralized operational management across restaurant locations.

Software Engineering Intern Medianet

I built an HR and project-management ERP with Odoo synchronization, employee dashboards, and task-management workflows.

The implementation used React, Node.js, and MySQL to support employee and project operations.

Software Engineering Intern CNI

I delivered a government e-learning platform with structured training modules and learner progress tracking.

I used Angular and Spring Boot with MySQL to implement the platform's learning and administration workflows.
