I build production AI systems and scalable backends — and privacy-first software in the open. Fast, secure, and honest with the people who use it.
A family of five privacy-first apps on one shared, encrypted foundation. No servers, no accounts, no telemetry — your data is encrypted on your device and never leaves it.
Every app shares one carefully built core — strong on-device encryption (AES-256), keys protected by your phone's secure hardware, and a clean, consistent design. Nothing is uploaded anywhere; there's no server to upload it to.
Never miss a dose. Schedules, adherence analytics, and reminders you can act on without opening the app.
Freelance invoicing done right — exact integer-cents money math and professional PDFs that always add up.
A private space to think — locked with your PIN or fingerprint, searchable, and beautifully calm.
A real password manager you own — master-password + biometric unlock, and it fills logins across your phone.
Lock any app behind your PIN or fingerprint — the open-source app lock without ads or tracking.
From real-time web platforms to machine-learning research — a sample of what I've built across the stack.
A real-time platform connecting blood donors and recipients directly — tackling critical blood-supply shortages, one request at a time.

I care about software that treats people honestly: no dark patterns, no silent data collection, no lock-in. That conviction became Secure Suite — four apps that keep every byte on your device and prove privacy and polish aren't a trade-off.
I'm an open-source advocate — I build in the open, write tests I trust, and document so others can build on it.
I'm open to roles and collaborations in AI, backend, and privacy-focused engineering. Let's talk.
