What I'm looking for

I seek an entry-level backend/blockchain role where I can build secure, scalable Web2/Web3 systems in Agile teams, optimize smart contracts and APIs, and grow in cloud infrastructure and DevOps practices.

I am a backend blockchain developer with internship and project experience building secure, scalable Web2 and Web3 platforms using Node.js, TypeScript, Solidity, AWS, Docker, and CI/CD. I deliver pragmatic engineering solutions focused on performance, reliability, and developer velocity.

During my internship I refactored Polygon smart contracts to reduce average gas usage by ~35% and cut on-chain execution latency by 32%, while contributing to automated Docker/GitHub Actions pipelines that sped environment setup and increased sprint velocity. I build Ethers.js integrations and integrate IPFS/Pinata for resilient data storage.

I have built RESTful backends (Node.js/Express/MongoDB) with Redis caching and real-time streams, and I authored an email-automation CLI in Python that improved deliverability and interview callbacks. I hold AWS Certified Cloud Practitioner and Web3 Development (Solidity) certifications and I thrive in Agile teams that value measurable performance gains.
