📍 Full stack engineering for complex backend systems
📍 AI Agent Development for automation and intelligent workflows
For more than 11 years, I’ve been working in mobile app development and full stack development, delivering scalable web platforms, high-performance mobile apps, and modern AI-driven systems.
This combination allows me to build products end-to-end, from mobile UI to backend architecture and AI logic.
📱 Mobile App Development & React Native Expertise
As a React Native developer, I’ve built and scaled mobile applications used in fintech, real estate, healthcare, marketplaces, and social platforms.
My mobile app development experience includes:
- Cross-platform iOS and Android apps
- Complex user roles and permissions
- Real-time features (chat, live updates, tracking)
- High-load backend integrations
- Clean architecture designed for long-term growth
One of my key projects Breeze, a real estate mobile platform was developed end-to-end as a full stack developer and later raised $3M+ in investments.
That experience strongly shaped how I approach architecture, scalability, and product quality.
🤖 AI Agent Development & Automation
In parallel with product engineering, I focus heavily on AI Agent Development.
As an AI Agent Developer and AI Automation Expert, I design systems that go far beyond simple chatbots.
I build:
- AI agents with planner-executor architecture
- Multi-agent systems with task orchestration
- AI chatbots connected to business data
- AI automation pipelines for operations, research, and analytics
- RAG systems using embeddings and vector databases
These AI agents are designed to interact with real systems, APIs, CRMs, databases, internal tools, and operate as part of a real product ecosystem.
My goal is always the same:
turn AI from an experiment into a reliable, controllable product component.
🔗 Where AI meets Full Stack Development
What makes my approach different is the combination of:
AI Developer + Full Stack Developer + Mobile App Developer
This means:
- AI agents integrated into web platforms
- Mobile apps powered by AI logic
- Backend services managing agent execution
- Dashboards for monitoring and control
- Secure and scalable infrastructure
Instead of isolated AI tools, clients get complete AI-powered products.
💡Clients usually come to me when they need:
- A senior engineer who understands product logic
- A CTO-level partner, not just a coder
- Clean architecture from day one
- Systems prepared for growth, investment, and scale
That’s why many clients stay long-term and treat me as a technical partner, not a temporary freelancer.
