3DCerts

I led the team building a blockchain-based certificate verification and issuance platform. The idea was simple: make it easy for employers to verify a candidate's credentials without jumping through hoops. We used the OpenCerts attestation library and IPFS for decentralized storage, and built both a verification portal and an issuance portal from scratch.

My Beneficiary

I built a Progressive Web Application (PWA) using React.js while interning at New Creation Church. It handled visit logging, attendance tracking, and the usual CRUD operations. I focused a lot on making the UX feel right for a church setting where not everyone is tech-savvy. Solid learning experience that taught me a lot about shipping real products.
