Services

I am an experienced web developer with over 15 years of expertise in PHP and Symfony. My focus is on developing robust and scalable web applications that seamlessly integrate into existing systems and meet the highest standards of performance and security.

Throughout my career, I have worked on a wide range of projects, from small startups to large enterprise solutions. This has given me deep insights into various industries and allowed me to develop customized solutions tailored to clients needs. My services include:

Custom Web Applications

  • Dashboards & Statistics – Custom dashboards with real-time data and charts for a quick overview.

  • User Management – Role and permission system for different user groups.

  • Automated Processes – Workflows to reduce manual tasks and errors.

Interfaces & APIs

  • Fetching & Providing Data – APIs for integrating external services (e.g., payment providers, CRM, ERP).

  • API Development – Custom APIs for your application to provide data for third parties.

  • Data Import & Export – Automated exchange of data with other systems.

Automation & Document Management

  • PDF Generation – Automatic creation of invoices, reports & other documents.

  • Email Processing – Automatic forwarding, storage, or response to emails.

  • Background Processes – Scheduled tasks for recurring operations (e.g., nightly data processing).

  • Google Login – Seamless login with a Google account.

  • Additional Logins – Integration of Facebook, Apple ID, or other providers.

  • Two-Factor Authentication (2FA) – Increased security with additional protection mechanisms.

AI Solutions & Intelligent Automation

  • Autonomous AI Agents (Agentic AI) - I build more than just chatbots; I develop intelligent agents that autonomously analyze processes, trigger APIs, and fully automate support or research tasks.

  • Secure Enterprise AI (RAG) – Development of AI assistants "fed" with your internal company knowledge to generate precise, privacy-compliant answers for employees or customers.

  • Automated Data Extraction – Transforming unstructured PDFs, invoices, and images into usable, structured data formats using modern AI models.

  • Visual AI Analytics – Implementation of image recognition systems that verify and evaluate objects, states, or documents in real-time.

  • Scalable Content Automation – Automated generation of high-quality, context-sensitive text (e.g., product descriptions, reports) that seamlessly integrates into your existing systems.

Performance & Security

  • Optimization – Faster load times through caching & performance tuning.

  • Security – Protection against attacks with the latest security standards.

  • Scalability – Solutions that grow with your business.
