Your engineer, inside your business, accountable end to end.
I embed in your team and carry the project from scoping to adoption, then stay to run what ships. Everything is documented, so the work never depends on me alone.
Embedded with teams at
Services
End-to-end software solutions tailored for enterprise complexity.
Custom Software Development
Full-stack applications built to your exact specifications — from internal tools to customer-facing platforms. Clean architecture, tested code, delivered on time.
AI & Automation Integration
Practical AI solutions that solve real business problems. Workflow automation, intelligent document processing, and tools built on the Claude API that save your team hours every week.
Cloud Architecture & Migration
Design and migration to modern cloud infrastructure. AWS, Azure, or GCP — optimized for performance, security, and cost. No over-engineering, no vendor lock-in.
Technical Strategy & Advisory
Fractional CTO-level guidance for teams making critical technology decisions. Architecture reviews, tech stack selection, and hands-on technical leadership.
How it works
One engineer. End to end.
I carry the whole arc — scoping, building, shipping, adoption — so one person is accountable for the outcome and nothing gets lost between handoffs.
Find where time is lost
I meet your people and teams, map where time is lost and where work is still done by hand, and identify the use cases worth pursuing.
Choose the first build together
Small enough to ship fast, but solving a real problem. We pick it together, and it's usually underway by week three.
Put working software in hands
Your team gets working software to try early and shapes it with feedback, so adoption is built in rather than bolted on.
Operate, or hand over
Once a system ships, I can stay to run it — updates, security, and model changes — so your tools keep working. Or I hand it over to your team with thorough documentation and runbooks.
Enterprise-proven.
Claude-certified.
I'm Justin Halaby, the engineer behind Groupe Justin. Since 2019 I've worked embedded in enterprise teams at CDPQ, National Bank, and CAE, building data platforms, cloud migrations, full-stack applications, and internal tools across finance, banking, and aerospace.
I hold the Claude Certified Architect credential at both the Foundations and Professional levels, and I ship Claude API systems in production.

One point of accountability
The engineer who scopes the work is the one who ships it and stays for adoption. No account managers, no handoffs.
Never a single point of failure
Every system ships with documentation and runbooks, so it can be run, audited, or handed over without me in the room.
AI-accelerated delivery
Claude Code and modern AI tooling are part of every phase of my work, shortening timelines without cutting corners on quality.
