I'm a full-stack developer and software architect who transforms complex business problems into elegant digital solutions. Currently leading backend development at Varuna Marine Services in Amsterdam, I specialize in building cloud-based systems, AI-powered automation, and mobile applications that work reliably even without internet connectivity.
Over the past 6+ years, I've helped businesses across multiple industries—from maritime and fintech in Europe to healthcare and education in India. I've built platforms that process millions in transactions monthly, connect hospitals with international patients, and help students worldwide learn new skills. My work with AI and automation has helped companies save hundreds of hours of manual work.
What drives me is creating technology that makes a real difference. Whether it's designing systems from the ground up, building intelligent automation that works like magic, or creating mobile apps that run smoothly on any device, I focus on delivering solutions that are both powerful and user-friendly. I believe great software should be reliable, fast, and easy to use.
Beyond coding, I'm passionate about AI innovation, building automation tools, sharing knowledge through live coding sessions, and helping aspiring developers grow their skills. I believe in continuous learning and giving back to the developer community.
