// Executive Professional Profile

01.OVERVIEW
Senior Software Engineer & Software Architect with 10+ years of experience engineering complex digital platforms. Specialized in bridging business goals with resilient, highly scalable, and long-lasting technical architectures. Covers the entire product lifecycle: requirement analysis, domain modeling (DDD), system architecture, full-stack development, automated QA, and cloud infrastructure. Combining software engineering with a strong background in Data Intelligence (Big Data & BI), I excel at executing greenfield products as well as modernizing legacy systems with zero downtime.

// Core Engineering Capabilities

02.CAPABILITIES

End-to-End Product Engineering

Translates strategic goals into production-ready software: functional scoping, domain modeling (DDD), resilient API design, modern reactive full-stack development, and automated QA.

Software Architecture & Legacy Modernization

Pragmatic architectural design using DDD, Clean Architecture, Hexagonal patterns, and Modular Monoliths. Conducts deep technical audits, technical debt reduction, and zero-downtime refactoring.

Data Intelligence, BI & AI Integration

Leverages a solid academic foundation in Big Data & BI (Master 1) to build robust data pipelines, executive BI dashboards, and embed tailored AI capabilities (LLMs, RAG architectures, intelligent agents).

DevOps, Cloud & DX Tooling

Pragmatic and automated infrastructure setups: Docker containerization, reverse proxy configuration (Caddy/Nginx), robust CI/CD pipelines (GitHub Actions), and developer velocity tooling.

Co-Founder & CTO — Glaxuss Tech

2024 — Present

Technical Leadership, Native Cross-Runtime Architecture & Cloud Infrastructures

  • › Architecture & Domain Scoping: Modeled complex decoupled system architectures built on SOLID principles and Domain-Driven Design (DDD).
  • › Cross-Runtime Engineering: Engineered native cross-runtime software foundations unifying and optimizing executions across Node.js, Deno, and Bun environments.
  • › Cloud Orchestration & CI/CD: Orchestrated high-availability cloud infrastructure and automated deployment pipelines ensuring seamless continuous delivery.

Founder & Lead Software Architect — Sikessem (Digital Operating Ecosystem)

2020 — Present

Modular Digital Operating System (DOS) & Multi-Tenant Foundations

  • › Ecosystem Vision (DOS): Engineered a modular platform foundation supporting strict organization-level multi-tenancy.
  • › Core Module Engineering: Developed essential building blocks: Core, Auth, Marketplace, CMS, Learning (Studium), Communication (Shub), and the SigUI Design System.
  • › Ecosystem Tooling: Created Cup (a fast selector-driven HTML/Markdown template compiler for Deno/TypeScript) and Loom (a decoupled backend framework).
  • › Delivery Pipeline & Automation: Automated multi-environment CI/CD workflows (GitHub Actions), Docker deployments, and Caddy reverse proxy routing on Linux VPS setups.

Senior Software Engineer & Architecture Consultant — Independent Consulting & Enterprise Clients

2016 — 2024

Custom SaaS, Fintech, Executive BI Systems, E-Commerce & Legacy Refactoring

  • › Legacy Modernization & Refactoring: Conducted system audits and executed progressive zero-downtime refactoring from monolithic codebases to Clean Architecture / DDD.
  • › Full-Stack Engineering: Engineered high-performance backend systems (Laravel, Symfony, PostgreSQL, Go) coupled with modern reactive frontends (Astro, Vue.js, Inertia.js, Livewire, Alpine.js, Tailwind CSS).
  • › Fintech & Financial Integrations: Integrated secure mobile payment gateways (Moov Money, card processors) and split-payment microservices (Spring Boot / Angular).
  • › Business Intelligence & AI Agents: Built custom analytics dashboards, automated ETL data pipelines, and integrated RAG architectures with LLMs for intelligent search and reporting.
  • › Enterprise Solutions: Delivered custom software systems for the Tunisian Post, multi-vendor marketplaces (Melanoderme), LMS platforms (Studium), and resort digital systems (Mawla Kiélé).

Maintainer & Active Contributor — Open Source Community

2020 — Present (Intensified since 2022)

Languages, DX Tooling, Web Frameworks & Automation

  • › Core Web Framework Contributions: Recognized code contributions to major web ecosystem projects (specifically Astro / Qwik integration).
  • › Language Specification & Compilation (Phi): Authored specifications for Phi (a PHP superset written in Vlang): EBNF grammar, lexer, parser, REPL, and strict error handling via native `or` blocks.
  • › CI/CD & DX Tooling: Created the Setup JS GitHub Action for environment provisioning, along with Tailwind CSS extension tools (colorwind, plugwind.js).
