Principal Software Engineer · VML
Antoine Debes
I design and build the systems behind enterprise platforms — back-end, data and front-end — and lead the team of ten senior engineers that ships them.

One developer, the whole platform.
The areas I work across, around the person who connects them. Hover to highlight an area, click it to see what I bring there.
Back-end
Services and APIs that stay boring under load, so the team can ship fast on top of them.
- REST and GraphQL APIs in TypeScript and Node.js
- Service boundaries, queues and background jobs
- Authentication, sessions and permission models
- Caching, rate limits and idempotent writes
- Structured logs, tracing and alerting
Databases
Schemas that survive their second year and queries that stay fast as the data grows.
- Relational modelling, migrations and constraints
- Indexing, query plans and slow-query budgets
- Redis for caching, sessions and queues
- Document stores where the shape really varies
- Backups, retention and restore drills
Data & analytics
From raw events to numbers people act on: pipelines, models and dashboards that are trusted.
- Event tracking plans and data pipelines
- Warehouse models and reporting layers
- Dashboards with KPI definitions everyone agrees on
- SQL and Python analysis, experiment read-outs
- Web performance and product analytics
Cloud & DevOps
Infrastructure as the quiet part: deploys that are routine and rollbacks that are instant.
- CI/CD with preview environments and release gates
- Containers and infrastructure as code
- Cloud platforms and the edge (Cloudflare, AWS, Azure)
- Secrets, environments and configuration
- Monitoring, SLOs and incident response
AI & automation
AI inside real workflows, with schemas, review queues and a human gate on everything that ships.
- Agentic coding and QA pipelines for delivery teams
- LLM-powered business automation with audit trails
- Prompt, tool and evaluation design
- Reviewing AI-authored pull requests
- Guardrails: what the model can and cannot touch
Front-end
Fast, secure and still immersive: 3D and motion that earn their place on a mid-range phone.
- React, Next.js and TypeScript
- Three.js, React Three Fiber, SVG and motion
- Core Web Vitals budgets and performance reviews
- Content Security Policy and a strict security baseline
- Design systems and accessibility
Team leadership
Ten senior engineers, one bar: planning that keeps scope honest and reviews that keep quality up.
- Planning: shape the problem, slice work for review
- Code review standards and a shared definition of done
- Architecture decisions, written down
- Mentoring, hiring and growth plans
- Estimates and stakeholder communication
