Experience

绿色交换API |管理和跟踪食品和食谱的碳足迹

http://docs.greenswapp.com/

我独自设计并实现了GreenSwapp API. The API is used to track the carbon footprint of food products and recipes and was written with Go, gRPC, and the PostgreSQL database. I also created user payment and checkout APIs and collaborated with front-end engineers to implement an online grocery delivery app.

用于业务洞察的数据仓库

http://app.data4life.care

I collaborated with multiple stakeholders to gather requirements to architect a data warehouse for the company using design documents in a remote setup. 一旦架构完成, 我和其他工程师一起实现事件驱动的数据管道.

数字健康|医患数据共享

http://app.data4life.care

I led a company-wide OKR to enable patients to share end-to-end encrypted data with their doctors. By scanning a patient-generated QR code or going to a URL and entering a PIN provided by the patient, the doctor could access the patient's information from an end-to-end encrypted platform.

该项目涉及在OAuth 2之上分层加密协议.0, 通过快速原型实现用户研究, 并与第三方合作进行渗透测试.

第三方端到端加密的JavaScript SDK

http://app.data4life.care

As part of the team, 我实现了端到端加密, zero-knowledge healthcare platform for patients and a JavaScript SDK executing the designed encryption protocols. Partners and third parties would later use this SDK to send encrypted healthcare data to the platform and decrypt that data according to FHIR standards.

Angular-Spring Web Portal

I developed a user management portal for a company operating in the healthcare industry, 使用AngularJS和Java Spring框架. This portal forms an interface for doctors and nurses that gives them access to all patient details and records and helps them organize their tasks and appointments. The app was presented to CEOs of many medical organizations and was highly appreciated.

专用于POS系统的数字收货系统

http://www.youtube.com/watch?v=O7xlQhfnNIU
