Software Architect · Go & Distributed Systems · 20+ Years Experience — Paris, France
Download: English PDF · French PDF
I build and run event-driven, high-volume data platforms in Go, and I carry the pager for what I design. My speciality is modernising systems under live traffic — taking legacy services off the critical path and rebuilding them in Go on hybrid multicloud Kubernetes while holding low-millisecond p99. I fix the upstream libraries production depends on rather than working around them.

Experience
Software Architect — Weborama
Feb 2019 – Present · Paris
- Lead the architecture and hands-on development of the migration of Weborama’s collect services from Perl to Go on fasthttp — the highest-traffic path, sustaining tens of thousands of requests per second and millions of events per day at low-millisecond p99.
- Drive the adoption of AI-assisted development at Weborama (Claude Code, Gemini, Spec Kit), defining the practices the engineering team works with today.
- Own design decisions end to end and implement them personally, working as an individual contributor or leading teams of up to five engineers.
- Operate over 90 Go services across hybrid Kubernetes — on-premise datacenters on Proxmox, GKE, and Yandex Cloud — deployed by GitOps with Flux and Argo CD, on Docker, Helm and Terraform.
- Share the 24/7 production on-call rotation for the platform — incident response, root-cause analysis and postmortems, plus the Grafana dashboards and alerting design that keep the pager meaningful.
- Design event-driven, high-volume data processing across several backend systems on Kafka and Redpanda Connect, backed by Couchbase, MySQL, Redis, RabbitMQ and AWS S3/SQS.
- Build the internal gRPC APIs (geolocation, ID sync) and the Weborama Contextual API, which derives audience profiles from page URLs.
- Architect the privacy layer: IAB TCF v2.3 consent handling including disclosed vendors, built in Go on prebid/go-gdpr alongside custom decoding.
- Own the client-side JavaScript: the browser collect tags deployed across client sites, and the Weborama Real-Time Data module contributed upstream to Prebid.js.
Backend / Software Engineer — Weborama
Apr 2013 – Feb 2019 · Paris
- Rebuilt the collect layer from Perl to Go and moved it onto Kubernetes, starting the migration later directed as architect.
- Built real-time bidding integrations with Google Audience Manager, Xandr, Yahoo, Criteo and The Trade Desk among 10+ ad-tech partners — over SOAP/REST, Protocol Buffers, cookie-matching pixels and FTP feeds for DMP and DCO.
- Built Weborama’s first queue-based service on the existing Redis deployment using rpush/lpop, adding no new infrastructure — the company’s first move to asynchronous processing, later carried onto RabbitMQ.
- Cut latency across the Big Data infrastructure with Riak, Redis, Lua and Bloom filters; added cardinality monitoring using Elasticsearch, Kibana and HyperLogLog.
- Delivered GDPR support across backend and frontend, and built the Weborama CrossDevice identity graph.
Open Source
174 merged pull requests to projects maintained by others.
- Redpanda Connect — Sustained upstream maintenance across three areas: new and extended connectors (Elasticsearch v9, SQLite driver, Couchbase scopes, kafka_franz topic control, cache components); remediation of roughly nine Go security advisories; and codebase-wide quality work including linter enablement and the mapstructure migration.
- Go ecosystem — valyala/fasthttp — the HTTP engine behind Weborama’s collect path — plus google/go-cloud, redis/go-redis, gofiber/fiber, twmb/franz-go, grpc-ecosystem/go-grpc-middleware, testcontainers-go, rabbitmq/amqp091-go, hamba/avro, go-playground/validator, googleapis/google-cloud-go.
- Own tools — structalign (struct field-alignment savings as a diff) and xpool (type-safe generic object pool), both accepted into awesome-go; go-claimcheck (claim-check pattern over blob storage and Pub/Sub); runtimevar-consul (Go CDK driver for Consul KV).
- Perl / CPAN — MooX::Role::Parameterized, Riak::Light (a fast, lightweight Riak client), GDPR-IAB-TCFv2 consent parsers in Perl and Lua. Stack Overflow: top 5% in bash and perl.
