Product delivery, release operations, and cross-team code quality.
About
I build and ship iOS features for a large-scale telecom platform supporting 60M+ subscribers, focused on product delivery, release operations, engagement systems, and code quality.
Outside my day job, I'm building Astrologie, an AI chatbot for Vedic astrology.
I’m currently based in Manila, Philippines 🇵🇭. When I step away from Xcode, you can usually find me experimenting with moka pot brews or leveling up my Spanish (currently fighting my way through A2 🇪🇸!)

An iOS chat app for Vedic astrology. Ask a question, and the reading streams in as it's generated. SwiftUI and MVVM on the device; a Supabase Edge Function in front of Gemini on the server.

Gemini
Streamed AI replies
Replies stream in over Server-Sent Events; a reply only counts as complete when the final event arrives, otherwise the partial text is kept with a “cut off” error.
The AI sits behind a server
The Gemini key, system prompt, and guardrails live in a Supabase Edge Function, so the model can change without an app release.
Guardrails in code
Gemini safety settings, a jailbreak denylist checked before the model is called, and a check on every streamed chunk.
Reporting and abuse limits
Per-user rate limit, per-conversation turn limit, and a “Report Message” action; if limits can't be checked, the server refuses.
Accessible
VoiceOver announcements that don't re-read a streaming reply, Dynamic Type, and a Report action in the rotor.
