What I'm looking for

I seek senior full-stack roles building scalable web/mobile products that leverage AI, strong engineering practices, and opportunities to mentor and lead teams.

I am a Senior Software Engineer with over 10 years building modern, scalable web and mobile applications across frontend and backend stacks. I specialize in React, Next.js, Vue, React Native, TypeScript, and AI-powered solutions including OpenAI API and LangChain.

My work includes architecting full-stack solutions and microservices using Node.js (Express, NestJS), Python (Django, FastAPI), PostgreSQL, MySQL, and MongoDB, and deploying on AWS and GCP with Docker and Kubernetes. I design REST and GraphQL APIs to improve performance and reduce data over-fetching.

I have led engineering teams, defined architecture, mentored developers, and introduced DevOps practices and CI/CD pipelines that dramatically reduced deployment times. I implemented testing strategies (Jest, Cypress, PyTest) and best practices that improved reliability and reduced post-release bugs.

I deliver production-grade AI integrations—NLP, recommendation systems, chatbots, RAG/LLMs—and build cross-platform apps with React Native, always focusing on scalable, maintainable code and measurable user impact.
