Fullstack Blockchain Engineer
Peeple.live
2024 - 2025
1. Blockchain Development: Smart Contract Development & Deployment: Writing and deploying smart contracts across multiple blockchain networks (e.g., Ethereum, Solana, etc.). Ensuring the contracts are secure, gas-efficient, and meet the business requirements. Blockchain Integration: Building integration layers between the blockchain and the Peeple.live platform to facilitate seamless interactions. This may include wallet integrations, token transfers, and decentralized finance (DeFi) functionalities. DApp Development: Developing decentralized applications (DApps) that interact with the blockchain, ensuring they are both functional and secure. This involves working with frontend and backend technologies to create user-friendly interfaces and efficient backends. 2. Backend Development: API Development: Designing and developing RESTful or GraphQL APIs to enable the frontend and blockchain components to interact efficiently. Database Management: Managing databases (SQL/NoSQL) to store and manage off-chain data. This would involve structuring data that is used in conjunction with blockchain interactions. Server-Side Logic: Writing server-side code using Node.js or other backend technologies to handle application logic, user authentication, and blockchain interactions. 3. Frontend Development: User Interface Development: Building and maintaining user interfaces (likely in React.js or similar frameworks) that allow users to interact with blockchain features like wallet connections, transactions, etc. Web3 Integration: Integrating Web3 libraries (e.g., Web3.js, Ethers.js) into the frontend to allow users to interact with smart contracts directly from their browsers. 4. Collaboration & Leadership: Team Collaboration: Working with other developers, designers, and product managers to define and implement features that integrate blockchain technology into the platform. Code Reviews & Mentorship: Conducting code reviews to ensure best practices are followed and mentoring junior developers on blockchain-related tasks. 5. Security & Testing: Security Audits: Ensuring that the smart contracts and the entire blockchain ecosystem are secure. Performing audits and working with external auditors if needed. Unit & Integration Testing: Writing tests for both the smart contracts and the full-stack application to ensure that everything functions as expected and is free of vulnerabilities. 6. Optimization & Scaling: Performance Optimization: Optimizing both the frontend and blockchain interaction to ensure the application is responsive and efficient. This includes improving gas costs, reducing transaction times, and ensuring the UI is quick and responsive. Scalability: Ensuring the backend and blockchain interactions are scalable to handle increased loads as the user base grows. 7. Blockchain Research & Strategy: Staying Updated on Blockchain Trends: Continuously researching emerging blockchain technologies, scalability solutions (e.g., Layer 2 solutions), and new protocols to integrate into the platform. Contribution to Strategy: Collaborating with the team on blockchain strategy and deciding which technologies and platforms to adopt in the future.
