I am a Senior Software Engineer with over 7 years of experience building scalable and efficient applications in the Web2 space. My core expertise lies in Python (Django, Flask) and cloud technologies (AWS, GCP), which I've used to lead teams, develop features, and implement robust CI/CD pipelines, directly increasing revenue and performance for fintech and SaaS companies.
Now, I'm channeling this proven skill set into the Web3 ecosystem. I am actively building and contributing to on-chain projects to deepen my practical knowledge. You can see my recent foray into smart contract development and dApp creation on my GitHub, where I'm working with Solidity and other core Web3 technologies.
I am passionate about leveraging my strong backend and DevOps background to build the next generation of decentralized, user-centric applications.
Let's connect and build the future of the web.
