Led the IAM authorization overhaul: 250+ PRs across 42 repositories, largely executed by AI coding agents from a written spec; 300+ API routes secured and 11 production services cut over with zero auth incidents (feature flags)

Ship at high velocity across the whole stack: 1,200+ PRs authored in 2026, many driven through coding agents

Led the 2026 geocoding centralisation: every call behind one service (~85% served from cache) and a cheaper provider chain, as accurate as Google, projected to cut geocoding costs by ~95%

Mapped the full system landscape (~50 services across 4 business domains) and drove its decommissioning: 11 legacy services retired in 2025, 15 more through the 2026 migrations

Co-built the team's AI tooling: 5 Claude Code plugins (platform knowledge, preview environments, NestJS migration agents, Metabase and Steampipe connectors), MCP access to staging/production data, and ported our design system and a full back-office prototype to Claude Design/Artifact

Lead the 5-developer Core team with 2 senior PMs, and hire (3 offers made in Oct 2026)

Own the architecture end to end: services split by business domain, 500+ REST endpoints, RabbitMQ across 38 services

Took part in Trusk's 2024–25 shift from a project to a product organisation: feature teams with their own PM and tech lead

Led delivery of the new central back-office within a year: one tool for ~150 internal users (customer care, dispatch, transport), built to retire 2 legacy back-offices and the legacy auth system

Took the generic State/Status engine from design study (6 architectures compared, up to Temporal workflows) to production: lifecycle roll-up across orders, missions, tasks and roundtrips, now ~74,000 state updates a day

Drove the data-model redesign (Order → OrderMission → Mission) and managed the plan to cut off the legacy one-entrypoint distributed monolith

Shipped 20+ retail client integrations; the 34 new B2B clients onboarded over the period (Point P, Sweeek, Poltronesofa, Conforama…) billed ~€7.9M by Nov 2025. Drafted the technical generalisation of client interop (generic EDI parser and readers, shared EDIFACT library…)

Helped steer all the application changes of the move from hosted VPS to Kubernetes, then redesigned the dev & release process across 60+ services (GitHub Actions shared workflows, semantic-release, Renovate, Terraform-managed permissions): release preparation time divided by ~3

Led “Maillage National” (Oct 2023 – Mar 2025), Trusk's expansion across France through regional carriers (Goevia, LGT…): ~€190k of revenue in its first 6 months, ~15,000 deliveries and ~€640k over the project

Managed the Order Taking squad (4 developers, reporting to the CTO) in Scrum on Linear, writing ~2,300 tickets, and its roadmap with the Product Manager

Main developer of the B2B pricing engine: per-client price grids for ~10 retail accounts (IKEA, Alinéa, Conforama, Fermob…) billing ~€1.6M a year

Ran cross-service platform migrations: 161 PRs across 22 services (container builds to Google Container Registry, shared CI configs, Datadog tracing); moved 9 micro-services onto the shared RabbitMQ module with AsyncAPI docs

Main backend developer of the first version of the driver-app API (alpha 2 → 6); built the push-notification and SMS-template micro-services from the first commit; redesigned the WMS (Warehouse Management System)
