Overview

Headed backend architecture in Go (Gin) and frontend development in JavaScript. The database was designed with PostgreSQL and the blockchain integration was implemented using Web3.js. I co-facilitated the project’s focus groups, created a wireframe, and worked closely with the stakeholders to refine requirements and validate progress.

Highlights

• Client Collaboration:
  • Co-facilitated a two-part focus group with the client.
  • Created study forms, drafted questions, and took notes.
  • Consulted regularly with the client to review progress and debrief functionality.
• Design:
  • Created a full wireframe for the project using Sketch.
• Backend Development:
  • Built and updated PostgreSQL, (refactored from a) MySQL database; created models and wrote create/update queries.
  • Implemented Go (Gin) server.
  • Added OAuth2 authentication in Gin.
  • Implemented cookies and session handling in Gin.
• Frontend Development:
  • Built HTML templates for the Go server with JavaScript, jQuery, and Bootstrap.
  • Validated JavaScript forms using regular expressions.
• Blockchain Development:
  • Developed an ERC-20/270 token buying site using Solidity, JSON, and JavaScript.
  • Integrated Web3.js API calls for blockchain contract and transaction interactions.
  • Used Truffle-Contracts for contract management.
  • Created a wallet that users could load with Ether.
• Testing:
  • Tested blockchain interactions with Ganache, Metamask, Geth, and the Ethereum test networks Rinkeby and Robsten.
  • Verified form handling and wallet transactions.

Challenges & Solutions

• Routing problem in Go frameworks: Reached out to peers and mentors for help and improved debugging approach.
• Complexity of blockchain tooling: Leveraged test networks and local tools (Ganache, Metamask) to validate transactions without risk.
• Collaboration hurdles: Coordinated with teammates on JavaScript and Go issues, and created internal documentation (e.g., Accord365 Mobile Todo doc) to improve organization.

Collaboration

• Paired with teammates on JavaScript and Go issues.
• Regularly interfaced with the client, ensuring transparency and alignment.
