About
Senior Full-Stack & Mobile Engineer | React Native, TypeScript, Node.js & AI Integration
Senior Full-Stack and Mobile Software Engineer with 8+ years of experience building and scaling applications across staffing, logistics, travel, healthcare, and EdTech. I specialize in React Native, TypeScript, React, Node.js, and AI-powered application development.
I've built products from the ground up, modernized existing architectures, and delivered applications serving thousands to millions of users. My experience spans mobile development, backend APIs, multi-tenant platforms, third-party integrations, and technical leadership.
Most recently, I developed AI-powered recruiting workflows for a staffing platform, including an AI recruiter processing approximately 3,000 candidates monthly and an AI supervisor monitoring more than 1,000 active jobs daily. I also launched a workforce-management mobile application used by thousands of people to track approximately 32,000 working hours each week.
My AI experience includes OpenAI integrations, prompt engineering, RAG, embeddings, and LLM-powered workflows. Beyond AI, I've helped improve mobile revenue contribution, developed white-label applications, and established frontend architectures adopted across multiple products.
I enjoy working closely with product and engineering teams to turn complex requirements into reliable, intuitive applications, balancing user experience, maintainability, and business impact.
