Full Stack Engineer

E-commerce delivery, Casablanca. I co-founded it and built the real-time logistics platform. 1,000+ deliveries tracked a day, event-driven services holding 5,000+ concurrent users, payment gateways clearing 30,000+ EUR a month. Drivers, dispatchers and customers all watching the same map at the same second.

Logistics software gets judged on a Friday evening, when a driver's phone dies. A dropped event there is a real person standing at a door with a box and no address, and a customer already on the line. Latency, retries and idempotent writes were not implementation details. They were the product.

Co-Founder

Cerion Srls. My own software company. It builds and runs its own products instead of selling hours, which means owning the whole thing: the code, the infrastructure, the billing, the support inbox. Run from Milan, registered in Rovigo, P.IVA 01692660291.

Cerion is the holding company behind GrowGanic. The product's footer reads "a Cerion company" and the site's structured data names Cerion as the parent. That is deliberate. Anyone checking whether a real registered company sits behind the product should be able to look it up instead of taking my word for it.

Founder

Software and digital marketing agency. Remote, from Casablanca. 20+ applications delivered, and behind them the work that never makes a case study: leading monolith-to-microservices migrations on systems that had to keep serving traffic the entire time, which in practice means arguing about what should never be split.

The agency is also where I watched SEO from the inside. The keyword sheet, the brief, the writer, the edit, the upload, the wait. Every one of those steps is a person, and the client pays for all of them. GrowGanic is the argument that none of it has to be.

Full-stack Developer

Eight years, 25+ clients, 8 countries, remote from Casablanca long before remote was normal. E-commerce platforms, payment integrations, real-time applications. Mostly the unglamorous middle of the stack: checkout that must never double-charge, webhooks that vanish if you are careless, the retry that will cheerfully turn one order into two.

Nobody was hiring me off a CV. The work had to speak first, and I got paid when the thing worked, not before. That is where the habit came from. It is also why building GrowGanic alone felt ordinary rather than heroic.

Autonomous SEO engine. You add a domain and you are done. It crawls the site, finds keyword gaps in live Google results, writes the article, scores it, and puts it past a gate that can refuse to publish. Then it ships to your CMS or a blog it hosts, tracks the rank daily, and rewrites the page when it slips. Starts free.

Built alone since April 2026. 1,423 commits, sole author.

Deleting the human step is a systems problem, not a prompt problem. Most of the work is plumbing nobody sees.

• A graph executor built from scratch on a job queue. Topological sort, parallel steps, retries and timeouts per step, and crash recovery for runs a deploy or an out-of-memory kill dropped mid-flight, guarded so a recovery run that crashed cannot loop. Twelve autonomous pipelines run on it: content, refresh, keyword research, rank monitoring, site audit, competitor analysis, AI visibility, link building and more.
• A 64-signal scoring engine that throws several signals straight out, because those were

I build GrowGanic, an autonomous SEO engine. Add a domain and do nothing. It finds the gaps, publishes the article.
