Frameworks are guests here.
Ten years with Spring taught me to love it — at the edges. The heart of a system is plain Java that doesn't know Spring exists. When the framework changes its mind, the business logic shouldn't have to care.

The craft, as principles.
folio ITrust nothing at the door.
Banking teaches you this fast: data that walks in unchecked becomes a production incident on a delay. I validate at the boundary and fail loudly. Bad news early is cheap — bad news late is a war room.
If it's clever, I rewrite it.
The best compliment a codebase can get is "boring". The next engineer — usually me, six months later — should read the code, not decode it. No magic annotations nobody remembers configuring.
Done means it survived production.
I've been the architect, the reviewer, and the guy on call. A feature isn't finished when it compiles — it's finished when it takes real traffic without waking anyone up.

From the workshop.
folio II
Open source · v1.0.0 on Maven Central
Tenantify
Zero-boilerplate row-level multi-tenancy for Spring Boot. One annotation on the entity — every query scoped to the current tenant, automatically. No repository changes, no findAllByOrgId() sprinkled through the codebase ever again.
how — Hibernate filters wired through Spring Boot auto-configuration; the mechanism disappears behind @TenantAware.
ships as — a Spring Boot starter · Java 21 · Hibernate 6.
Live · ships every Saturday 09:00
DevBrief
A news engine that reads the internet so I don't have to. Sources scraped daily, every article scored by an LLM against what actually matters — Java, architecture, DevOps, the craft — then compiled into one weekly digest. Built for an audience of one; the archive is open.
how — scraping pipeline · LLM relevance scoring · automated compilation & delivery, end to end.
runs on — a small Linux box that never gets a day off.
In development · 2026
Rovii
Turn driving into an experience. Set a duration — Rovii composes a real loop route from wherever you are and guides you through it. No destination. Just the road.
route engine — loop generation over real road graphs, tuned for the pleasure of the drive, not the shortest path.
stack — Spring Boot backend · Flutter client · Mapbox.
status — heads down. it ships when it's worth your time.
// the notebook has more pages — they surface when they're ready.
The record, briefly.
folio IIITen years inside French banking — KYC workflows, regulatory platforms, e-invoicing under finance law. Systems where a quiet failure costs real money, built to not fail quietly.
Led the Java 7 → 21 modernisation of mission-critical platforms, and a distributed team across Paris and Bangalore — architecture workshops, mentoring, clean-code culture as a practice, not a poster.
Banking sharpened the discipline — it doesn't own the curiosity. The same rigor travels: any domain where systems have to hold is interesting to me.
Senior craftsman by trade, builder by nature — the workshop is where the two meet.
