About Me

My background and journey

Available for work

I specialize in building robust, scalable applications across the stack — from intuitive mobile experiences to resilient backend systems. My tech toolbox includes Frontend technologies like React (Native & Web), Expo, TypeScript, Tailwind, ShadCN, and Backend with NestJS, Django, FastAPI, Firebase Functions, GraphQL, and REST APIs.

I enjoy crafting clean, maintainable codebases, optimizing developer experience, and exploring how AI can enhance real-world applications — especially in health, fitness, energy, and travel tech. I am the founder of MyndsIT, where I deliver cutting-edge solutions to clients and develop my own applications and SaaS products.

When I'm not coding, I'm exploring new technologies, working on AI integration projects, and staying up-to-date with the latest industry trends in web and mobile development.
