I rescued a hacked production server, migrated it, and hardened it end to end — with zero data loss.
A production site was compromised by malware exfiltrating data to external servers. I detected and removed it within hours, verified the system was clean, rotated all credentials, blocked the attackers at the firewall, and migrated the full Directus + Next.js site to a secure new server.
Then I hardened it: iptables firewall (default-DROP), Fail2ban, auto-updates, a 3-tier backup system, and hourly automated security monitoring.
Result: threat removed in hours, no data loss, server clean and continuously monitored, hosting cost cut ~$230/year, client fully owns everything.
This shows I don't just build systems — I keep them alive and secure under real attack.

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!
Check it out. Just built a workflow for a client outside of Contra. Their workflow was complex, but due to confidentiality, I am only allowed to share a generic pattern here with my audience. Please have a look and enjoy the case study!
Stratum - Cloud Infrastructure Management Platform
When every screen has clusters, 4 resource bars per card, and a global traffic map - the biggest design risk is making it look like a server room threw up on the dashboard.
Engineers stare at this thing for 8-hour shifts. Green-on-dark gives just enough contrast to scan disk, RAM and CPU at a glance without burning your retinas. The color-coded utilization bars do the talking so you don't have to read numbers first.
