Full-Stack & Mobile App & CRM & Artificial Intelligence Expert with over 8 years of experience designing and developing high-performance applications for web and mobile platforms.

My technical expertise spans modern frontend frameworks (React, Angular, Vue, Next.js), backend development (Node.js, Python/Django, Java/Spring Boot, .NET Core), and mobile platforms (React Native, Flutter, Swift, Kotlin). I am also skilled in cloud computing (AWS, Azure, GCP), containerization and DevOps (Docker, Kubernetes, CI/CD), and databases (PostgreSQL, MySQL, MongoDB, Firebase, Redis). In the AI domain, I have built intelligent agents, RAG pipelines, and AI-driven SaaS solutions, leveraging frameworks like LangChain and integrating LLMs (OpenAI, HuggingFace, Anthropic) for tasks such as automation, decision-making, and conversational AI. My ML expertise includes computer vision, predictive analytics, and NLP applications such as chatbots, sentiment analysis, and text classification. I have successfully delivered projects across FinTech, Healthcare, E-Commerce, Travel, and EdTech, integrating complex workflows, APIs, and real-time features to provide seamless user experiences.
