Frequently asked questions
Where do you operate as an IT developer?
Home base: Yerres (91), France. Software development, website creation and maintenance are delivered remotely from the Yerres office — efficient, no travel fee, anywhere in France or internationally (video for scoping, collaborative tools for follow-through). On-site meetings (scoping, delivery, client reviews) are possible: free travel within a 25 km radius of Yerres, then €1 / km beyond. Computer support: on-site, remote, or by hardware drop-off at the Yerres address. Long on-site consulting engagements (multi-month at a client site) are possible on quote.
What is the difference between software development and website creation?
Website creation targets a public audience — a brochure, catalogue or e-commerce storefront. Software development targets a tool used by a specific user inside a workflow (ERP-like apps, internal tools, API integrations). Both are covered; a free audit helps pick the right fit.
Do you offer ongoing maintenance contracts?
Yes. Monthly contracts cover preventive maintenance (updates, backups, monitoring), hosting, ticket-based support, and an envelope of development hours. Ideal to keep a website compliant and a business tool reliable.
What are typical lead times?
Brochure site: 3 to 6 weeks. Business tool: 1 to 4 months depending on complexity. Computer support: within 48 h on-site in the local radius, within 24 h remotely. Each quote ships with a realistic timeline.
