Daniel Cadeau

Software Engineer

Freelance since early 2026, after four years on a production application in the finance and insurance sector. I can lead a project solo or join an existing team.

Book a slot

Full-stack development & automation.

I can step in from the very first scoping of a project, or join one that’s already underway, depending on what’s needed. I can also automate business processes: data processing and transformation, file generation, syncing between tools, API integration or setting up automated workflows.

Services

Full-stack web applications

Design and development of custom applications, from interface to database and deployment, aligned with your business processes.

Integrations & automation

Interconnection of your existing tools (payments, CRM, analytics) and automation of recurring tasks, tailored to your technical environment.

Taking over projects

Taking over an existing codebase to fix, stabilise or extend it, whatever its level of maturity.

Query your documents with AI (RAG)

RAG pipeline over your business documents: ingestion (OCR, chunking, embeddings), metadata-filtered vector search and grounded, sourced answers. Extensible to tool orchestration (SQL queries, computation) beyond document search.

Targeted features

Development of specific features (dashboard, booking flow, admin area, data import), integrated into a new or existing project.

How I work

Scoping

Defining the need, scope and priorities before any development begins.

Technical choices

Selecting technologies based on the project, budget and maintenance constraints.

Build

Development in iterations, with regular checkpoints and intermediate validations.

Delivery

Deployment, documentation and handover of access, with follow-up available afterwards.

Questions & Answers

How much does a project cost?

It depends on the scope. After a first call, I send a clear quote laying out what’s included and the timeline.

How long does it take?

It depends on the size of the project. I give an estimate up front and keep you posted as we go.

What happens after delivery?

You get the project, access and documentation. I can also handle maintenance and future changes.

What technologies do you use?

Depends on the project — what needs building, who’ll maintain it, hosting constraints and budget.
