Developer Platform & Backend Infrastructure
A backend for applications: documents with access rules, realtime subscriptions, user accounts and file storage, with a multi-tenant headless CMS on the same platform.
Personal Finance Application
Offline-first personal finance for tracking accounts, income and expenses. Data stays on the device in an encrypted database — no sign-up, no servers, no analytics.
Privacy-Focused Password Manager
An offline-first password manager. Vault secrets are encrypted locally with keys derived from your master password — no account, no cloud sync, no remote telemetry.
Every project starts as a problem worth solving, and ends as software people actually enjoy using.
Your passwords. Your vault. Your privacy.
A privacy-focused password manager for Android, desktop and iOS, built on Kotlin Multiplatform with an offline-first vault.
View Project
A small, independent project can move carefully. These four ideas shape how each product gets built.
Interfaces that feel natural.
Clean, maintainable and scalable software.
Security and privacy considered from the beginning.
Build products around real user needs.
No step gets skipped because a deadline is close. This is what turns a problem worth solving into software worth keeping.
Research the problem, users, and requirements.
Create modern, intuitive, responsive UI/UX.
Develop secure, scalable, maintainable software.
Test, optimize performance, accessibility, and details.
Release, monitor, iterate, and continuously improve.
Decisions about data are made before the first line of code — what gets stored, where it lives, and who can read it.
The vault lives on the device. There is no account to create and no server holding a copy.
The vault file is encrypted on disk; the app works with decrypted data only in memory while unlocked.
Unlock keys are held by the Android Keystore and the iOS Keychain rather than written into app storage.
Auto-lock on a timer and on backgrounding, so an unattended unlocked device does not stay unlocked.
Engineering notes, security explainers and product updates as they happen.
