Aphra: proactive AI with the user still in control.
A production personal-AI product used by 60K–70K people. The system turned signals across email, calendar, reminders, and 14+ connected services into prioritized insights and reviewable actions—not another chat interface.
The hard part was not generating text. It was maintaining enough cross-service context to detect what mattered, queue it for the right user, and create a safe action boundary before anything consequential happened.

- Operated BullMQ orchestration for close to one million background jobs across user, admin, recommendation, synchronization, and notification workflows
- OAuth integrations that brought email, calendar, and contextual signals into one workflow
- A proactive detection loop that surfaced time-sensitive items before a user had to ask
- Review-first action flows with clear approve, edit, dismiss, and recovery boundaries
- Full-stack delivery across mobile, web, APIs, identity, integrations, and production edge cases

Client feedback
What clients have said.
“He took the time to really understand the functionality of the application in order to deliver code that worked correctly and according to spec. We had a number of QA cycles internally to greenlight the app and Christos turned around bug fixes and minor enhancements quickly allowing us to move forward into user testing much faster than we anticipated.”
