I donโ€™t just write code โ€” I build real products. From empty repos to deployed apps, I own every step of the software lifecycle. Having worked end-to-end in fast-evolving, real-world startup setups, I bring a deep understanding of how to ship production-ready, SEO-optimized, and user-centric products from scratch.

๐Ÿ’กMy experience covers a range of role โ€” from SDE to Full Stack Developer โ€” and contributed across the stack with strong hands-on expertise in:

๐Ÿ”น ๐—™๐—ฟ๐—ผ๐—ป๐˜๐—ฒ๐—ป๐—ฑ: React.js, Next.js, TailwindCSS, TypeScript, Angular, Redux
๐Ÿ”น ๐—•๐—ฎ๐—ฐ๐—ธ๐—ฒ๐—ป๐—ฑ: Node.js, Express.js, MongoDB, Firebase, PostgreSQL, graphQL
๐Ÿ”น ๐——๐—ฒ๐˜ƒ๐—ข๐—ฝ๐˜€ & ๐—–๐—œ/๐—–๐——: GitHub Actions, Vercel, Netlify, Docker, AWS
๐Ÿ”น Agile teams, scalable architectures, REST APIs, and rapid prototyping.

I thrive in dynamic environments where I can combine technical depth, product thinking, and execution speed to build software that delivers real impact. Whether itโ€™s bootstrapping a new feature, optimizing page performance, or scaling systems, I bring a builderโ€™s mindset with a focus on clean code and long-term maintainability.

๐Ÿ“ˆ Open to exciting opportunities where I can continue solving meaningful problems and build with great teams.

Letโ€™s connect โ€” Iโ€™d love to collaborate and code something impactful together.
