Ferryroute is a website and mobile application selling ferry tickets from 42 European companies. The application is already available on the Google Play Store and will eventually be released on the iOS App Store.

I designed, implemented, and deployed the whole system. On the back end, I implemented a custom framework, a resource system inspired by data-driven development, sourcing the data from different APIs. On the front end, I built a framework on top of Vue, allowing fast implementation of new functionalities and pages.

I designed an AI orchestration platform supporting multiple local and commercial language models, with explicit context management to control agent behavior and coordination. I implemented a fully voice-driven interaction layer, enabling voice-based control of the system and spoken responses from specialized agents. I also implemented Docker-based isolation as the main security boundary, with MCP servers enabling agents to interact with local resources, including their own code, through controlled interfaces.

A tool I designed after years of experience in server maintenance. A custom shell built on top of Bash and a framework to build amazing scripts for servers. Includes automatic Pandoc documentation, command line auto-completion, text formatting (colors, style, icons, and tables), and a Debian package builder.

What I feel should be the right way to write code, a modern language I implemented built on top of Common Lisp and its associated interface, dedicated to website development in a serverless infrastructure. An attempt to bring a new programming paradigm to the market!

I developed the entire application, including the back end in PHP/MySQL and the front end in Vue.js. A data-driven reporting application with dynamic forms and graphs, including a timeline, a histogram, a pie chart, and a data table, all with interactive, highlighting, grouping, ordering, and filtering capabilities, and the ability to display records on a map too.

I implemented a custom WebQL-like SQL language to support the report application using prepared statements to avoid any SQL injections.

I developed the entire application: the back end in PHP/MySQL and the front end in Vue.js. The main screen is a Gantt chart where we can add and edit tasks with simple drag and drop. The system recognizes managers and people assigned to tasks across multiple projects and avoids time overlaps. It also takes into account weekends and bank holidays, so the duration of a task is known on both business days and regular days.

The Order Monitor is a Vue.js application for restaurants to track their online orders, from pending to delivered. It takes into account client specificities and includes grouping, ordering, and filtering functionalities.

I developed a security-focused web portal that safeguards sensitive internal workflows by utilizing behavior-based access control, eliminating the need for exposed authentication endpoints. I implemented a custom PHP routing layer and employed a hardened NGINX configuration to minimize the attack surface and prevent direct route discovery.

In addition, I applied advanced PostgreSQL access controls with strict role separation to ensure data isolation and maintain resilience even in compromised scenarios. I designed environment-aware error handling and containerized the system using Docker Compose, ensuring predictable behavior across both development and production environments.

I provided ongoing full-stack maintenance and support for a UK eCommerce platform that sells bundled study resources and tutoring services.

The engagement was retained rather than feature-driven, with a focus on fast turnaround for time-sensitive changes, where delays caused operational discrepancies. My work included updating tutor pricing and availability across both the database and the interface, fixing front-end and back-end defects as they were reported, running weekly site maintenance checks, and deploying patches on notification.

I kept a live commercial platform accurate and stable on a low, predictable weekly commitment, with quick response to urgent requests.
