Four focused offers, from a one-day landing page to a full enterprise platform or corporate AI system. Each has a transparent starting price and a realistic delivery window.
Custom backends, complex API migrations, multi-client SaaS platforms, and enterprise architectures with role-based access and secure integrations, backed by 25+ years of production PHP/Symfony experience in regulated industries.
Turn corporate documentation, PDFs, and enterprise files into secure, high-accuracy conversational knowledge bases with hybrid retrieval (dense, keyword, and graph).
Codebase-aware AI assistants, multi-agent task routing, tool integration, and custom LLM workflows for the enterprise.
Fast, responsive business sites with SEO foundations and clear contact or booking paths.
Selected projects
Enterprise platforms and AI systems delivered for pharmaceutical and regulated-industry clients. Client names are withheld for confidentiality reasons.
PROJECT 01 — AI / RAG
A hybrid-retrieval RAG assistant that indexes internal quality-management documentation (SOPs, risk analyses, audit and supplier-qualification questionnaires) for a pharmaceutical group. It also generates a knowledge-graph wiki and supports questionnaire extraction and answers with AI.
Indexed 884 documents (868 succeeded) in a dense + keyword + knowledge-graph retrieval pipeline, which automatically extracted 6,673 entities across 425 wiki pages.
PROJECT 02 — MULTI-AGENT AI
A custom multi-agent Q&A assistant that routes end-user and support questions about a large Symfony platform across 9 specialized domains (FAQ, workflows, configuration, API usage, security/GDPR, feature planning, bug reports), with evidence-based, source-cited answers.
Acts as an AI assistant for an 800+ file, 180+ entity production Symfony 6.4 codebase.
PROJECT 03 — ENTERPRISE PLATFORM
Lead developer for a medical-information management platform that handles medical inquiries, FAQs, and pharmacovigilance and quality-complaint workflows for pharmaceutical companies.
Deployed and maintained for 39 pharmaceutical and health client projects.
PROJECT 04 — REGULATORY COMPLIANCE
Symfony application for the full lifecycle of Pharmacovigilance System Master Files: versioned publishing, complete audit trails and diffs, correspondence tracking, and scheduled compliance alerts.
Generates regulatory documents in multiple formats (HTML / PDF / Word) and keeps a complete version history for compliance teams.
PROJECT 05 — TURNKEY STATIC SITE
A custom single-page site for a Paris-based event decoration and hosting studio (weddings and anniversaries), delivered as the flagship example of the Turnkey Corporate Static Websites offer.
Fully trilingual (FR / EN / ZH), with a filterable portfolio gallery, testimonial carousel, and validated Formspree booking form.
PROJECT 06 — E-LEARNING PLATFORM
Symfony-based learning management system that delivers SCORM-compliant course content, tracks learner progress, and manages certifications, with SAML SSO for enterprise access and dedicated theming for each client tenant.
Runs 11 branded client tenants from a single codebase, each with its own theme, configuration, and SSO integration.
PROJECT 07 — HEALTHCARE MEDIA PLATFORM
A full-stack Symfony content platform for healthcare professionals that aggregates news, congress replays, expert interviews, and podcasts, all tagged and filterable by medical specialty. Rebuilt with a public REST API and back office, it supports two navigation experiences, by content type and by univers, from one backend.
Content tagged across 40 medical specialties and 6 content verticals (univers), delivered through a public REST API that supports two navigation models.
PROJECT 08 — INTERNAL ENTERPRISE PLATFORM
As lead developer, built a confidential enterprise operations platform covering project administration, time and leave tracking, expense approvals, organisational access controls, reporting, and engineering activity data.
A single secure workspace for operations, approvals, and reporting, with enterprise authentication and role-based access.
