Project delivery
A scoped build, senior-led end to end.
You bring a defined problem; we architect, build, and ship it. The engineer who designs the system stays on it through delivery. There's no hand-off to a junior bench.
Engineering Services for Canada & the US
Backend, cloud, and AI engineering for the systems your business runs on.
Enterprise backends, secure AWS architecture, AI and LLM integration, and written technical assessment, delivered by the team that builds and operates 4 software products of its own. Serving clients across Canada and the United States, remote-first, Eastern Time.

What We Do
The work we're engaged for
Six disciplines, each backed by systems we've shipped and still run in production today.
Backend & API engineering
Java and Spring, TypeScript and Next.js, Node.js. REST API design, versioning, authorization models, and third-party integration built to run under real load.
Secure AWS architecture
Serverless and containerized workloads on Lambda, ECS Fargate, and Kubernetes. Terraform-managed infrastructure and zero-downtime CI/CD with OIDC federation, so no long-lived cloud credentials sit in the pipeline.
AI & LLM integration
Provider-abstracted model integration, so you are never tied to a single model vendor. Structured output, access governance, and OAuth-secured MCP servers exposing governed tools to AI clients.
Legacy modernization
Java EE to Spring Boot, application-server migrations, and on-premises to cloud transitions. We have delivered all of these in production at enterprise scale without stopping the business.
Application security & privacy
OWASP-guided design and review, OAuth 2.0/2.1 and JWT authorization, and verification with penetration-testing tooling. GDPR production experience in the EU; PIPEDA-aligned practice in Canada.
Technical assessment & due diligence
Architecture and code review, technical-debt and scalability analysis, and vendor or platform evaluation. You get a written report an executive can act on.
How We Engage
Three ways to work with us
Whatever the scope, the delivery model stays the same: a senior engineer architects the engagement, leads it, and stays on it. Pricing follows scope, and we put it in writing after the first conversation.
Senior capacity
A senior engineer or architect inside your team.
Fractional or full-time. Useful when your roadmap outruns your hiring, or when a system needs an owner with more depth than the team currently has.
Technical assessment
A fixed-scope review with a written report.
We examine a codebase, an architecture, or a vendor claim against how it will actually behave in production, then write up the findings for the executive who has to decide.
Why This Firm
We run production systems of our own
Most consultancies advise on systems they'll never operate. CS2 builds and runs its own, and that changes how we build yours.
AgentlyLeads, our multi-tenant AI CRM, runs 130+ REST endpoints on AWS with zero-downtime deployment. Notermed, our clinical documentation platform, handles sensitive medical content under a restricted-access model. When we recommend an architecture, it is one we are answering for in production ourselves.
Behind that sit 18 years of enterprise delivery, including ten years on the REST backend platform of a Tier-1 telecommunications operator in the EU (the last three as a CS2 client engagement), on GDPR-regulated systems processing personal data at scale. We deliver in English, French, and German.
Frequently Asked
What clients ask before the first call
What does a technical assessment include?
A fixed-scope review of a codebase, an architecture, or a vendor claim, judged against how it will behave in production. You get architecture and code review, technical-debt and scalability analysis, and platform or vendor evaluation, written up as a report the executive who has to decide can act on.
Do you work with companies in the United States?
Yes. CS2 serves clients across Canada and the United States, remote-first on Eastern Time, from offices in Toronto and Milton, Ontario.
How do you price an engagement?
Pricing follows scope, and we put it in writing after the first conversation. There are three models: a scoped project delivered end to end, a senior engineer or architect placed inside your team on a fractional or full-time basis, or a fixed-scope technical assessment.
Who does the work?
The engineer who designs the system stays on it through delivery. There is no hand-off to a junior bench and no reassignment after the work is won.
Which technologies do you work in?
Java and Spring, TypeScript and Next.js, and Node.js on the application side. On AWS: Lambda, ECS Fargate, and Kubernetes, with Terraform-managed infrastructure and zero-downtime CI/CD through GitHub Actions using OIDC federation.
Can you add AI or LLM features to an existing product?
Yes. We build provider-abstracted integrations so you are never tied to a single model vendor, with structured output, access governance, and OAuth-secured MCP servers that expose governed tools to AI clients. We run the same approach in production on AgentlyLeads, our own CRM.
