Status

Open to senior roles

I architect resilient platforms where money moves and milliseconds matter — shipping Spring, Angular, React and Node systems for BPCE, Generali, Europe Assistance and BNP Paribas.

Six years inside Tier-1 banking and insurance — turning monoliths into microservices, SOAP into REST, and brittle legacy stacks into compliant, observable production systems. In parallel, 6+ years freelancing across e-commerce, education, events, AI, trading and SaaS — two practices running in harmony, one feeding the other.

I love the seam where deep banking domain knowledge meets modern engineering — and increasingly, AI.

(07)Dream & Perspective

The next decade of finance won’t be rebuilt — it will be re-imagined.

I want to spend the next chapter at the seam where regulated systems meet generative AI — replacing brittle batch jobs with autonomous services, turning compliance from a cost-center into a product surface, and giving European institutions the engineering velocity of a startup.

Less ceremony. More signal. Software that ages well.
