Are you developing a cutting-edge web or mobile application, an AI-powered digital assistant, or a custom platform driven by artificial intelligence? You need a senior engineer who can not only architect complex systems from the ground up but also craft responsive, high-performance user interfaces and embed powerful AI capabilities in a seamless and scalable way.


With over 7 years of experience as an AI-oriented full-stack developer, I specialize in blending modern frontend engineering with practical and advanced AI integration. I bring a unique combination of skills that enables me to deliver pixel-perfect, intuitive user experiences, while also developing intelligent, scalable software systems that generate real-world value.

🚀 Frontend Engineering Expertise

Modern UI/UX Development: Extensive hands-on experience with React.js, Next.js, and TypeScript to create lightning-fast, responsive, and maintainable web interfaces that drive user engagement and retention.


Component-Based Architecture: Skilled in designing scalable and modular component systems, advanced state management using Redux and Context API, and optimizing performance for frictionless user experiences.


Design Systems & Collaboration: Adept at building and maintaining scalable design systems, working closely with designers using tools like Figma, Storybook, and Tailwind CSS to ensure brand consistency and UI cohesion.


Mobile App Development: Proficient in building high-performance, cross-platform mobile applications using React Native 📱, with optimized experiences for both iOS and Android ecosystems.


Accessibility & SEO: Following frontend best practices to ensure applications are accessible, discoverable, and high-performing across all devices and screen readers.


🤖 Advanced AI Capabilities

Practical AI Applications: Embedding AI models into real-world web and mobile products to deliver intelligent features such as conversational chatbots 🤖, smart search engines, content generation systems, and voice-enabled assistants.


AI Frameworks & Tools: Deep familiarity with a broad suite of AI technologies including OpenAI (GPT-3.5/4), Claude, Gemini, DeepSeek, ElevenLabs, Whisper, Dialogflow, LangChain, and more—seamlessly integrating them into user-facing interfaces.


Custom AI Pipelines & Workflows: Designing and implementing end-to-end AI workflows, including prompt engineering, data integration, and real-time operations using platforms like Supabase and Firebase.

From MVP to Production: Rapidly developing AI-driven MVPs and scaling them into robust, production-ready systems such as recommendation engines, natural language processing (NLP) tools, computer vision solutions, and dynamic knowledge bases.


Thank you!

    The standard of Filip's work has been excellent - fast and thorough. He went deep where it mattered, especially on the security side, and communicated clearly at every step, flagging risks and trade-offs instead of glossing over them. Reliable, professional, and a real pleasure to work with. Highly recommended - looking forward to continuing together.

    Working with Filip has been excellent. He built a complex data reconciliation engine for us and the quality of the core logic is outstanding: across thousands of independently verified values in our acceptance testing we found no calculation errors. Just as valuable, when our testing did surface issues he root caused and fixed them fast, with clean explanations and tests added for every fix. He communicates clearly, estimates honestly, answers hard architecture and cost questions directly, and delivers when he says he will. We are continuing the project with him and I would gladly recommend him for any demanding backend or data engineering work.
