Frandzdy S.

I design and make reliable Symfony applications in production, where data rigor tolerates no approximations: asset management, transactions, dematerialization, connected business systems.

13 years of experience on demanding projects, currently in fund management (private equity / private debt).

I work on architecture, APIs, migrations, and audits — from transactional back-office to third-party component integration: investment process automation, subscription management, document generation.

Representative projects:

→ Asset Management (PE / Private Debt) — Full-stack development on a financial platform where data integrity and reliability are paramount. Automation of investment processes, subscriptions, document generation.

→ Audiobooks Platform (Lead Dev) — Responsible for the Symfony/PHP back-office and API, consumed by a React front-end, for a consumer application.

→ Dematerialization for a certification body — Symfony/MariaDB application interfaced with a complex ecosystem (Sage, Docuware, Office 365, Maileva, Google Maps, API Gouv.fr). Zero paper objective, simplified file management.

→ Recycling Management and Secure Geolocation Music Streaming Platform — Two very different business contexts, same need for adaptation.
