Product Nerd — SaaS Product Management Platform
Project Goals: Product Nerd is a Laravel-based SaaS platform for product management and competitor monitoring. It tracks competitors' blog posts via CSS selectors, manages customer data, handles bug/feature reporting, and provides an inbox system — all with role-based access control (Spatie permissions), Livewire UI, and Paddle payments.
My Contributions:
New feature: Built the Competitor Radar system — a scheduled command that scrapes competitor blogs for new posts using configurable CSS selectors, indexes them, and sends email/Slack notifications when fresh content is detected (CompetitorRadarCommand, FetchCompetitorBlogPosts job, event-driven notification flow)
Bug fixes: Resolved favicon rendering, toast styling for long messages, DOM diffing issues, selected inputs tab state, and fixed integration tests after code refactoring
Test suites: Wrote comprehensive Pest PHP test suites across 15+ feature tests covering Bugs, Features, Structure, Inbox, Customers, ManageComponents, Competitor Radar, User Management, Authentication, Email Verification, and multiple integration tests (API, Email, External/Internal Portal)
Impact: Transformed the project from having minimal test coverage to a fully tested codebase with structured test patterns, ensuring reliability for the competitor monitoring feature and preventing regressions across core modules.

Solving the "Last Mile" in Enterprise SaaS: My Native Multi-Tenancy Architecture 🚀
Hey everyone,
After years of building Enterprise applications, I noticed a recurring bottleneck: we spend months just setting up the foundational plumbing (Data isolation, JWT, Billing, RTL support) before touching the actual business logic.
To solve this for my own freelance projects and agency clients, I spent the last few months building a production-ready Enterprise Boilerplate.
The Stack & Architecture:
Backend: Java 25 & Spring Boot 4
Frontend: Angular 21 (Standalone components)
Data Isolation: Native Hibernate Multi-tenancy (Strict schema/database separation per tenant)
Localization: Dynamic RTL/LTR with bilingual JasperReports generation.
I built this specifically to cut a 4-month MVP development cycle down to just 14 days without sacrificing bank-grade security.
I’ll drop the link to the live demo in the comments if anyone wants to see the architecture in action.
I’m curious to hear from other Fullstack Engineers here—how do you usually handle strict multi-tenancy in your freelance client projects?
Do you build from scratch every time, or rely on specific patterns?
Would love to discuss architecture and share insights!
