Web applications
Fast, thoughtful web apps — dashboards, SaaS products, internal tools — built on a stack chosen for longevity, not hype.
Independent application development studio
Senechal Consulting is a small, senior studio that designs, engineers, and ships web & mobile applications — from the first napkin sketch to a product in production with real users.
01 — What we do
No hand-offs, no ticket factory. One team that owns the problem from interface to infrastructure.
Fast, thoughtful web apps — dashboards, SaaS products, internal tools — built on a stack chosen for longevity, not hype.
Native and cross-platform apps that feel at home on the device, with backends that keep them in sync.
The engine room: clean APIs, reliable data models, and services that hold up under real load.
From idea to a shippable first version — scoped tightly so you can learn from real users, fast.
Containers, CI, and boring-on-purpose infrastructure so releases are a non-event, not a fire drill.
Inherited a codebase that's holding you back? We stabilise, refactor, and get you moving again.
02 — How we work
We start with the outcome you need — not a feature list. A short, focused discovery to map the real problem.
Something clickable in weeks, not quarters. We de-risk the hard parts early, while decisions are still cheap.
Tight iterations, visible progress, and code written to be maintained by whoever comes next — including you.
Into production with monitoring, docs, and a plan. We stay as long as you need us, and no longer.
