Independent consultancy · Since 2010

Data moves. Software ships. Infrastructure holds.

DEXS builds the connective tissue between systems — custom development, data exchange, and infrastructure architecture for teams that need more than an off-the-shelf answer.

Services

Three practices. One way of working.

Every engagement is specific, but the core capabilities are stable. Pick what you need — or start a conversation about all three.

01

Data Exchange Solutions

Design and build reliable pipelines, integrations, and APIs that move data between systems — on your terms, with your schemas, at your scale.

  • REST, GraphQL & event-driven APIs
  • ETL / ELT pipelines & batch ingestion
  • EDI, file-based & legacy integrations
  • Schema design, validation & contracts
02

Custom Software Development

Product engineering for teams that need bespoke software — web applications, internal tools, and back-office systems built to fit the way you actually work.

  • Full-stack web applications
  • Internal tools & operational dashboards
  • Automation & workflow engines
  • Modernization of legacy systems
03

Infrastructure Architecture

Plan, provision, and operate the platforms your software runs on — from cloud landing zones to CI/CD to the observability that keeps you out of trouble.

  • Cloud architecture & landing zones
  • Containers, Kubernetes & serverless
  • CI/CD pipelines & platform automation
  • Observability, SLOs & on-call readiness

Approach

How the work gets done.

A lightweight process that keeps us honest: understand first, write things down, ship increments, leave it runnable.

  1. 01

    Discover

    Understand the real problem before touching code — stakeholders, constraints, existing systems, success criteria.

  2. 02

    Design

    Propose an approach with trade-offs written down. Agree on scope, interfaces, and what we will not build.

  3. 03

    Build

    Small increments, honest status, visible progress. Testable slices shipped continuously, not a surprise at the end.

  4. 04

    Operate

    Hand over what you can run — with documentation, runbooks, and a transition plan. Stay available for the long tail.

Stack we live in.

Tools are secondary to the problem, but these are where we have the deepest reps.

About

Built for work that does not fit a template.

DEXS Incorporated is an independent software consultancy based in Brossard, Québec, working with clients since 2010.

We specialize in the parts of a system that are too specific for packaged software — where an integration, a data model, or a platform decision will shape how a team works for the next decade.

Small by design. Senior by default. Direct engagement with the people doing the work.
