about

Over six years in web development, including two years as an independent consultant. I specialize in crafting custom digital solutions and advanced company management platforms that streamline business operations.

My approach is collaborative, focused on transparent communication and understanding the client's true goals. Each project is approached with curiosity and a commitment to ongoing learning.

I maintain a balanced lifestyle, drawing creative inspiration from kickboxing, reading, and family pursuits. This balance helps me bring fresh perspectives to every project.

case study

custom business management platform

comprehensive business solution

overview

Developed a comprehensive business management system.

challenge

The client needed a unified platform to solve operational pain points and improve visibility across employee records, live production tracking, cost monitoring, absence documentation, and inventory management.

solution

Designed and implemented an end-to-end web application with real-time analytics, KPI dashboards, and custom modules for employee management and inventory tracking.

outcome

The platform has significantly enhanced day-to-day efficiency—allowing management to track live production, monitor costs, manage absences and documentation, and optimize inventory. The solution continues to address evolving challenges, driving operational improvements and supporting business growth.

Outcome in practice

One operational view instead of scattered sheets: live production, costs, absences and stock — less manual follow-up for managers and clearer daily decisions.
