About Me
I help companies ship developer work with a clear scope: JavaScript/TypeScript apps (Angular & Next.js), Android (Kotlin/Compose), and Java/Spring Boot APIs — plus easy Google Sign-In and Apple Sign-In when the product needs auth.
What I deliver
- Web apps, admin panels, and landings (JavaScript, TypeScript, Angular, Next.js/React, Tailwind)
- Google Sign-In + Apple Sign-In (OAuth / Firebase Auth / Auth.js) so users log in in a couple of taps — web and/or mobile
- Android features (Kotlin, Jetpack Compose, Firebase / Play-oriented work)
- Java 17 + Spring Boot APIs, CRUD backends, and integrations (Stripe, email, REST)
- Bug fixes and scoped features in existing repos — short written plan before coding
How I work
- Developer-only scope: observable deliverables, acceptance criteria, and a demo
- Per-company auth checklist (Google Cloud / Apple Developer setup notes)
- Progress updates — not surprise rewrites or endless revisions

Send the brief (or repo link + goal). I’ll reply with a short plan, fixed-price estimate, and whether Google/Apple login belongs in v1.
