Technical and software architect
I design the infrastructures that move data between systems: high-volume messaging, data flows, integration of heterogeneous systems. Audit, expertise and architecture design.

Organisations I have worked for: CO-OP ev · FedEx · Nestlé · RTS (SRG SSR) · beta.gouv.fr · Electre Data Services.
An outside look at your RabbitMQ or NATS infrastructure: topology, configuration, consumers, monitoring. You leave with a diagnosis and a prioritised remediation plan.
For example: Messaging expert: infrastructure audits, Confidential clients
Distributed systems and high-volume data flows: exchange model, fault tolerance, well-argued technical choices, all the way to the architecture document your team will keep alive.
For example: Architect, distributed timer system, US startup (under NDA)
I take on development assignments when the domain and the technical depth are right: high-volume messaging and data flows, distributed systems, interoperability. The code starts from an architecture and explicit contracts, then is produced with AI inside a framework of tests and checks that I design and answer for. In Go, concurrent, lean and observable services; in Python, robust Django backends that are easy to take over. Delivery, taking over an existing codebase, code review, upskilling the team.
For example: Architect, distributed timer system, US startup (under NDA); Lead developer, DORA — GIP Plateforme de l'inclusion, beta.gouv.fr
Getting systems to talk when they don't speak the same version of the same protocol. Design and delivery, from the OCPI roaming hub to the interoperability test bench.
For example: Lead architect, OCPI roaming hub, CO-OP ev
Connecting a new service to an existing information system (reference data, formats, automated exchanges, rejection handling) and preparing its security accreditation.
For example: Tech lead, Portail RSE (CSR reporting portal) — beta.gouv.fr

An architect, and a long-time developer: I design what I could build myself, in Go, Python or Java. That is what makes an architecture realistic, and an audit useful to the team that receives it.
My common thread: moving data between systems that were never meant to talk to each other, from semiconductor fab metrology chains to FedEx's European network, all the way to an electric vehicle charging hub. I work for industry, banking, luxury, media and the public sector.
Freelance through my company, ikarius, remotely, about three days a week.

An audit to run, an architecture to design or review, systems that need to talk to each other: the simplest way to start is a first conversation.
