I’m midway through building a blockchain-powered product and now need a Bangalore-based engineer who can step in and test & deploy the smart-contract layer. The core logic is already sketched out in Solidity, but it still needs refinement, security hardening, full unit-test coverage, and clean deployment scripts. The contracts will ultimately plug into a custom backend that doesn’t fit the usual “website / mobile / enterprise” labels, so flexibility around APIs and integration patterns is essential. Expect to work with me in person for white-boarding sessions when necessary; the rest of the time remote collaboration is fine. Key outcomes I’m after: • Finalized, audited Solidity contracts deployed to a public testnet and then mainnet • Comprehensive test suite knowledge, Other relevant software working knowledge as well. • Knowledge in VPS configuration. If you’ve already done production smart contracts, understand common attack vectors, and can spare a few on-site meetings in Bangalore, let’s talk.

Drawing from my experience as a seasoned Full Stack Developer, I possess the necessary skills to take your smart-contract layer to the next level. Having developed complex web and mobile applications using extensive APIs, including REST and GraphQL, I understand your need for a flexible backend that integrates seamlessly with your custom solution. My ability to design, deploy, and maintain applications using Node.js (incorporating the JavaScript testing suite) aligns perfectly with your requirement for streamlined Solidity deployment and comprehensive unit-testing. In addition to my proficiency with Javascript and Node.js, I understand the ins-and-outs of VPS configuration—a crucial skill set for deploying your contracts on public testnets and then the mainnet safely. For this project's unique needs, I possess hands-on experience with AWS, Firebase, Docker, and other DevOps tools—I'm ready to utilize whatever platform best aligns with your specific requirements. Moreover, my familiarity with business automation & CRM/ERP systems would lend itself well to understanding and implementing meaningful functions in your non-standard backend. I understand that there may be occasions where close collaboration is necessary;

With a strong background in blockchain technologies, I am confident in my ability to complete and deploy your solid contracts. I've produced productions smart contracts before which explains my familiarity with the common attack vectors that could compromise the security of these contracts. As you require comprehensive test-suite knowledge, I assure you that my experience in full stack development will be instrumental in providing your contracts with the necessary refinement and security hardening. Working on blockchain solutions is distinct from creating mainstream applications or enterprise systems; from my profile, you can see that I have had extensive experience in dealing with unconventional systems as well as comprehensive web applications. Consequently, I am able to provide you with the flexibility needed for this project when it comes to APIs and integration patterns. My experience also allows me to anticipate potential difficulties we may encounter on the smart-contract layer during deployment and provides me with the adaptability necessary for onsite whit-boarding sessions.
