About Me

My interest in technology started with a simple question: how do well-designed systems stay fast, reliable, and easy to scale? That curiosity has grown into a practical engineering mindset shaped by core Computer Science fundamentals such as Data Structures, Algorithms, Networking, and Operating Systems.

Today, I build across Full-Stack web development (MongoDB, Express.js, React, Node.js), Robotic Process Automation with tools like Blue Prism, Automation Anywhere, and n8n, and Machine Learning projects that turn data into usable intelligence. I care most about writing clean, efficient, and scalable code that solves real problems without unnecessary complexity.

Outside of building projects, I like exploring system design, learning how different tools fit together, and turning ideas into something practical and usable. I’m always looking for opportunities to collaborate, improve, and create work that feels thoughtful and well engineered.

When I'm Not Coding

Beyond the terminal, I find my balance in simple moments — occasionally getting lost in books, walking alone under an open blue sky, randomly stepping out with no plan, fooling around with friends, or just staring at the stars and letting thoughts wander.
