Lead Software Engineer

AI-based digital health platform with privacy-centric design

MyUSE is an AI-based digital health startup. Development began following several years of research. I was hired to interpret the research, develop an MVP, and move the project into the commercialization phase.

Challenge

MyUSE faced the challenge of developing a privacy-compliant digital health platform that could scale to thousands of users while maintaining strict data protection standards and offering an accessible user experience.

Key Points

Creating a multi-tenant architecture that maintained data separation
Building a platform that met GDPR and healthcare privacy requirements
Designing an accessible interface that achieved perfect Lighthouse scores
Scaling to support 10,000+ users with efficient resource utilization

The Approach

Discovery Phase:

Worked with psychologists to understand research requirements
Mapped user journeys and privacy requirements
Defined technical architecture requirements

Planning & Strategy:

Developed privacy-by-design approach for all features
Created scalable multi-tenant architecture plan
Established accessibility standards and testing protocols

Achievements

📐 Architecture

Worked with a team of psychologists to interpret research and aid the development of a cross-platform web app
Implemented privacy by design approach
Architected a performant, cost-effective tech stack to meet short and long-term goals (AWS/Nuxt JS/VueJS, Laravel)
Scaled to 10,000 users & several tenants on AWS

🎨 Frontend Development

Developed the front-end with UX best practices and recent WCAG guidelines in mind
Liaised with UCC DSS services to ensure compliance
Achieved a 100% Google Lighthouse score

🏗️ Backend Development

Designed and implemented a multi-tenant backend architecture, considering scalability, performance, and long-term costs
Utilized Nginx, RDS, Aurora, Route53, EC2, S3

🛠️ Testing & Project Management

Provided tools to support development and synergize team output, such as an integrated CMS
Implemented automated testing and analytics (Docker, Selenium, PHPUnit, HotJar)

🔒 Privacy & Compliance

Adopted a privacy-by-design approach to development
Developed the privacy policy in line with UCC ethics and recent GDPR guidelines
Wrote and maintained the Data Protection Impact Assessment (DPIA)

Lessons Learned

What Went Well:

Privacy-by-design approach prevented later compliance issues
Early focus on accessibility standards simplified later development
Multi-tenant architecture allowed flexible client onboarding

Key Takeaways:

Frontend accessibility requires early planning and continuous testing
Privacy compliance documentation is as important as technical implementation
Multi-tenant architectures require careful planning for data isolation
