Personal Projects

SoloOpsProject & invoicing management web service for solo businesses (public demo)

A web service that centralizes clients, projects, tracked hours, invoices, and payments for freelancers and side businesses. I handle every stage on my own, from requirements definition through implementation to building and operating the AWS serverless infrastructure.

Demo account:demo@soloops.example.com/DemoPassw0rd!

A demo account preloaded with sample data. The server is stopped automatically to optimize costs, so the first access takes about 15 seconds.

OshibellCountdown iOS app (in development)

A countdown iOS app for fans of VTubers, cover singers, and streamers. Built as a backend-less MVP; I design and implement everything on my own, from the UI and data management to local notifications, widgets, and social-share image generation.
