About
Hey! I’m a passionate Full Stack Engineerwith 3+ years of experience building fast, scalable, and user-focused web and mobile applications. I started my journey crafting custom themes and quickly transitioned into developing modern, full-featured apps using React, Next.js, TypeScript, and Python (Django/Flask).
Currently, I work at Carret, where I architect and deliver end-to-end product features across web and mobile. I’ve built production-ready SDKs (Fluid), shipped core features like crypto SIPs and KYC systems, developed internal tools (KYC, accounting, ops dashboards), and launched mission-critical products like the OTC Desk — a key revenue driver. I also manage CI/CD pipelines and deployment workflows, ensuring reliable and secure releases.
Outside of work, I love experimenting with new full-stack tools, optimizing app performance, and working on personal projects — from component libraries to AI-powered apps. I enjoy sharing practical dev tips, code snippets, and learnings with the community through blogs and GitHub.
When I’m not coding, you’ll find me working out, exploring new tech trends, or spending time with friends and family. I’m always open to exciting collaborations and new challenges that push my limits — in tech and in life!
