About

🚀 I’m a Senior Frontend Developer with 4 years of experience building high-performance, scalable web applications across fintech, capital markets, and now the maritime and risk management domain. 💻 I have a strong command of React, Redux, Svelte, JavaScript, and TypeScript, with hands-on expertise in building clean, responsive, and secure interfaces. I’ve led development of complex UI workflows, optimized performance, and integrated APIs to deliver seamless cross-device user experiences. 🌍 My career spans working with leading fintech firms, where I gained deep insights into digital finance, user behaviour, and data-driven decision making, and now in the maritime industry, contributing to solutions that advance safety, sustainability, and global operations. 🤖 I also leverage AI tools (Cline , ChatGPT, Cursor, Copilot etc.) to accelerate development, improve debugging, generate test data, and demonstrate innovative POCs for team adoption. ⚡ Curious by nature, I learn fast, Google smarter, Prompt better, and thrive on solving problems with thoughtful design and maintainable code.
