ABOUT
Jeff Cadet
I’m a full-stack developer who builds production software end-to-end. Not prototypes. Not demos. Real products used by real people, running in production, processing millions of records.
My main project is TradeProof — a SaaS platform that verifies contractor compliance across all 50 US states. I built the entire stack solo: data integrations, REST API, billing system, security infrastructure, and deployment pipeline.
I also work directly with clients in three ways: web design & development, AI adoption consulting for small businesses, and certified Haitian Creole translation — from fashion e-commerce to civic platforms for the Haitian diaspora. And I teach the next generation of IT professionals as a Technical Trainer at Goodwill Columbus.
Fluent in English, French, Haitian Creole, and Spanish — which is why I build multilingual products by default, not as an afterthought.
How I work
Ship, then iterate
I'd rather launch something imperfect and improve it based on real feedback than spend months polishing in a vacuum. Every project I build is live and serving users.
Own the full stack
I don't hand off. Database schema, API design, frontend UI, deployment pipeline, security audit — I build and maintain the entire system. This means fewer integration bugs and faster iteration.
Security is not optional
TradeProof went through a 130-finding security audit before taking its first dollar. I pin dependencies, validate inputs, rotate secrets, and assume every boundary is hostile.
Build for the underserved
The Haitian diaspora has no comprehensive web portal. Small contractors can't easily verify licenses. Beauty professionals struggle with online presence. I build for the gaps others ignore.

Cloud & security labs
I learn by building. Alongside shipping products, I run hands-on labs on Microsoft Azure — a SOC detection stack in Microsoft Sentinel, identity on Entra ID, and the infrastructure labs I teach from.
SIEM & Detection Engineering
Microsoft Sentinel SOC Lab
A cloud SIEM homelab on Microsoft Azure: I onboarded Microsoft Sentinel, ingested ~24K security events, and worked detection end-to-end — scheduled analytics rules that raise incidents, KQL hunting queries, an investigation workbook, and a geo-IP enrichment SOAR playbook. Built toward the SC-200 Security Operations Analyst path.

Identity & Access on Entra ID
A Microsoft Entra ID lab covering the identity controls a SOC leans on: role-based access control, Conditional Access policies, MFA enforcement, and least-privilege access reviews.

Infrastructure
Windows Server + Azure AD Teaching Lab
The hands-on lab I designed for my CompTIA cohorts: each student provisions a Windows Server 2022 VM on Azure DevTest Labs and stands up Active Directory, DHCP, DNS, and VPN — backed by per-student Entra accounts and scoped RBAC.
