My Story

AI Solutions & Full-Stack Expert | Building Scalable Systems for Startup Growth

With over 1.5 years of experience in software development, I specialize in building modern, intelligent web and mobile applications that solve real-world problems. My journey started with a deep curiosity about how things work, evolving into a strong passion for AI, automation, and intelligent systems.

I craft scalable, maintainable solutions using technologies like Next.js, TypeScript, and Python. From cross-platform mobile apps with React Native to robust backend systems powered by FastAPI and MongoDB, I thrive in full-stack development with a performance-driven, clean-code approach.

Currently, my focus is on integrating AI agents leveraging tools like OpenAI Agents SDK and LangChain into everyday digital experiences. I'm exploring how automation, data intelligence, and modern web technologies can be combined to power the next generation of AI-first applications, SaaS products, and robotics-driven tools.
