Case Studies

Showing how I think.

Case studies help companies understand not only what I built, but how I think about problems, structure and improvements.

Demjansped Logistik CRM/SaaS

Problem

A logistics business needs a clearer way to manage requests, clients, offers, jobs, vehicles, employees, documents and invoices.

Solution

I built a CRM/SaaS prototype with a practical operational flow: Inquiry → Client → Quote → Job → Employee/Fleet → Documents → Invoice.

Features
  • • CRM modules for clients, quotes, jobs, fleet and employees
  • • Quote view with PDF/email direction
  • • Job assignment logic
  • • Activity logs and status tracking
  • • Admin dashboard layout with TailwindCSS
What I learned

This project helped me understand real business flows, database relations, modular PHP, PDO queries, dashboard design and backend debugging.

Next improvements
  • • Add user roles and permissions
  • • Improve migrations and seed data
  • • Add more automation with n8n
  • • Improve reporting and finance analytics

AIHub.mk

Problem

Small businesses often need automation and AI workflows, but they need clear explanations and practical solutions, not complicated technical language.

Solution

I started building AIHub.mk as a brand and platform for presenting automation ideas, AI agents, workflows and digital business systems.

Features
  • • Modern website structure
  • • AI assistant page direction
  • • Service/use-case content
  • • Automation workflow planning
  • • n8n-based backend direction
What I learned

I improved my ability to present technical work as business value, plan automation services and connect web systems with AI workflows.

Next improvements
  • • Add real case studies
  • • Connect lead forms to n8n
  • • Add multilingual content
  • • Add analytics and conversion tracking

Learning & Growth

I am actively improving.

As a junior developer, I do not pretend to know everything. I focus on learning consistently and applying that knowledge in real projects.

Modern PHP structure

Improving modular PHP structure, reusable helpers, better routing, cleaner file organization and more professional backend patterns.

Laravel and APIs

Learning Laravel, REST API design and more scalable backend architecture for future client-ready systems.

Security and deployment

Improving authentication, CSRF protection, server hardening, SSL, Cloudflare settings, Nginx configs and safe deployments.

JavaScript architecture

Improving frontend structure, components, modals, fetch requests, UX interactions and cleaner JavaScript patterns.

Open to opportunities

Looking for real work and growth.

I am looking for a place where I can contribute, improve, learn from better developers and work on real systems.
