Cover image for Senior Full Stack & AI Engineer – React, Node.js, Python, LLMs
I'm a Senior Full Stack Developer with 10+ years of experience building scalable web applications and AI-powered systems from the ground up.
What I build:
High-performance frontends with React, Next.js, Vue.js, and Nuxt
Robust backend APIs with Node.js (Express/NestJS), Python (Django, Flask, FastAPI), and Laravel
LLM-driven features and agentic workflows using OpenAI, Claude, Gemini, and LangChain
Cloud-native systems on AWS/GCP with Docker, Kubernetes, and CI/CD pipelines
Why clients choose me: I bridge product, business, and engineering — translating complex requirements into clean, maintainable systems. Whether you need an MVP built fast or a production-grade platform scaled reliably, I deliver end-to-end.
Industries I've worked in: SaaS · E-commerce · Fintech · AI Products
