Engineer who builds production Go: a server-side event collection service routing to multiple ad platforms, memory-optimized hot paths that helped halve cloud cost, and ETL running on Nomad. I operate what I build, including the pager.

Client and company code is private, so these are described by problem and outcome.
Problem: Client-side tracking lost conversions and could not feed several ad platforms reliably.
What I did: Built an event collection service in Go, containerized and run on Nomad, that processes events and routes them to multiple destinations such as Meta and Google Ads.
The foundation of the company's tracking and attribution pipeline.
Problem: Cloud spend was growing faster than traffic.
What I did: Found obsolete and cost-heavy services to replace or remove, and rewrote hot production paths in Go to save memory.
50% lower GCP cost.
Problem: Analytics queries on 10M+ records were too slow for real-time diagnostics.
What I did: Designed a two-node ClickHouse cluster and migrated from MySQL with a blue-green strategy and no downtime.
100x faster queries and real-time diagnostics.
Problem: Shopify merchants needed analytical answers beyond what standard tools offer.
What I did: Designed and built an orchestrator from scratch that processes complex user queries, with OpenTelemetry tracing across the whole system.
Insight queries standard tooling could not answer, fully observable in production.
Problem: Recurring pipeline failures were being found by customers, not by us.
What I did: Centralized monitoring over infrastructure, application and data-quality signals, plus restart, rollback and database-recovery runbooks with post-recovery validation.
Recurring failures turned into alerts and repeatable procedures; MTTR down 65%.
Problem: One-hour manual releases.
What I did: Jenkins, SonarQube and Git pipeline with quality gates and test-driven development.
15-minute automated deploys, 85% code coverage.
I work remotely from Tunis with managers and a team based in Paris. Tunisia is on UTC+1 all year, so I overlap France's working day almost entirely.
I took on-call and overnight pager duty for production systems, so I know that remote reliability means alerts, runbooks and clear handoffs, not being in the room.
Post-mortems, runbooks, architecture decision notes and benchmark reports. I leave a trail someone else can pick up without a call.
Promoted to Technical Project Lead to run five-plus workstreams and coordinate priorities and deadlines, all remotely.
Italian citizenship: no visa or sponsorship needed to work in the EU.
