Hi, I'm John Rizal
Senior .NET developer and solution architect with 10+ years of experience building enterprise systems, SaaS platforms, and automation tools.
I've led teams at Accenture, built production SaaS used by real customers, and worked with clients across the US, Australia, New Zealand, Canada, and Asia.
When you work with me, you get direct access to a senior developer—no handoff to juniors, no account managers in between. Just clear communication and quality code.
365Sentri
A Microsoft 365 monitoring and automation SaaS platform I co-founded and built from the ground up.
The Challenge
MSPs and IT teams managing Microsoft 365 tenants needed a way to monitor mailboxes, automate routine tasks, and get alerts before issues became problems.
The Solution
Built a multi-tenant SaaS platform with real-time monitoring, automated workflows, and a plugin-based architecture for extensibility. Integrated deeply with Microsoft Graph APIs.
My Role
Lead architect and sole developer. Designed and built the entire platform—backend APIs, Angular frontend, Azure Functions, event-driven messaging, CI/CD pipelines.
