Outils navigateur pour découper des CSV, formater du JSON, éditer des PDF, supprimer l'arrière-plan d'images et bien plus — traitement 100% local, sans upload, sans inscription, sans tracking.
Users who routinely process small data files were forced through SaaS upload flows that demanded accounts, leaked sensitive data to third-party servers, and broke under offline conditions.
Engineered every tool — CSV splitter, JSON formatter, PDF editor, background remover, image converter — as a fully client-side module. Heavy parsing pushed to WebAssembly workers, zero analytics in the tool path, and a unified toolkit shell delivered through Next.js with edge caching.
This engagement combined several of ConfiaTech's core capabilities. Each contributed a specific outcome to the final product.
Every case study on this site follows the same delivery spine — the four-phase process we have refined across fifty-plus production engagements.

Production rollout, observability, incident response, feature evolution.
Every contributor on the engagement had at least five years of production experience. No learning on the client dime.
Outcomes — not deliverables — drive the roadmap. Weekly demos report progress against the metric, not against the backlog.
Production observability, incident playbooks, and handoff documentation ship with every release.
The same engineers who built the product support and evolve it. Institutional knowledge stays inside the engagement.
