ANIMAL HELP NOW / VOLUNTEER ENGINEERING

Two apps. One response network.

From wildlife emergencies to neighborhood pet evacuations, two products help people act quickly when animals need them most.

Animal Help NowWILDLIFE EMERGENCY RESPONSE · U.S.
01Encounter02Match03Contact

Fast, appropriate help for wildlife emergencies.

Animal Help Now connects people across the U.S. with nearby wildlife rehabilitators, rescues, hotlines, and veterinarians. It replaces frantic searching with location-aware guidance so an injured, orphaned, or distressed animal can reach appropriate help quickly.

MY IMPACTI conceived and owned the entire Kotlin Multiplatform rebuild, carrying it from product direction and research through UX, architecture, implementation, testing, launch, and release. I was accountable for every phase and every major product decision.

Trusted neighbors helping pets reach safety.

PHaR helps people alert and coordinate trusted contacts when pets need evacuation or care and their owners cannot get home. Owners can prepare a support network in advance, share essential pet and access information, and reach the right people during an emergency.

MY IMPACTI led Android from architecture through release, directly managing two contractors and two volunteers while coordinating delivery, QA, documentation, and weekly planning. I turned the product direction into an organized, shippable implementation.
