I build line-of-business Symfony applications that hold up in production.

Years of Symfony and Prestashop. I build the intranets, client portals and e-commerce modules you need when SaaS runs out of room — and I wire them into Microsoft 365, SharePoint and the private APIs you can't move.

JACK FUMANCHU ● PAR

One developer, two hands, no subcontracting.

jackfumanchu is the name I freelance under. I design, build and ship myself — from wireframing the flows to the production deploy, including the documentation your team will actually read.

I work solo for IT departments that need a single point of contact, and pair with other freelancers when a project calls for it. Engagements typically run from 3 weeks to 6 months.

What I make.

§ 01 · services

/ 01

Bespoke Symfony applications.

Intranets, back-offices, client portals, internal tooling. Clean architecture, tests in place, observability by default. Ships with operations documentation.

SYMFONY

/ 02

Prestashop modules.

Payment, ERP, logistics and BI modules wired into your existing tools. Compatible with PS 1.7 / 8 / 9 and ready for the next major bump.

PRESTASHOP

/ 03

Microsoft 365 & SharePoint integrations.

Azure AD authentication, SharePoint read/write via MS Graph, user provisioning, Teams synchronisation. No sidecar, no lock-in.

MS 365

/ 04

Secured APIs.

Design, signing, rotation, documentation. When two systems need to talk without giving anything away — public front, intranet, ERP, external partners — I draft and plumb it.

§ 02 · case studies

Line-of-business intranet wired to Azure AD & SharePoint.

An industrial client needed an intranet that recognised Microsoft 365 users and read & wrote directly into SharePoint libraries — no overnight ETL, no document copies, no homemade cache layer.

OIDC authentication via Entra ID, document access through MS Graph, permissions mirrored on the Symfony side, Redis cache for listings with webhook-driven invalidation. Rolled out progressively, zero downtime, ~2,400 active users.

Registration portal synchronised with the core IS.

A public registration form that, in real time, provisions a user in the business intranet and a guest in Azure 365 — with signed requests, rotating secrets, and automatic compensation if either step fails.

The whole chain is idempotent: replaying a message won't create duplicates. The internal team follows registrations from a live dashboard; errors surface in the existing tracker.
