Every year, millions of digital lives vanish. Social media platforms freeze accounts or delete data after a period of inactivity, because of death. Families lose thousands of photos, years of thoughts, and the voice of those they loved-simply because no tool exists to rescue them.

In Ukraine, this is a crisis of national memory. For families of fallen heroes and millions of displaced people, a digital memorial isn't a luxury; it’s the only way to stay close. We are building the "Digital Vault" that turns fragile social media archives into a permanent family legacy.

The Technical Challenge (What you will build)

We have the concept, the design, and the waitlist. We need you to build the Digital Archeology Engine.

1. The Parser (The "Moat"): Build a system to ingest massive, messy ZIP archives from Meta/Google, extract metadata, and auto-reconstruct a chronological life story.
2. AI Narrative: Use LLMs to transform raw data into a human-readable biography.

3. The Phygital Bridge: Create a web-first ecosystem where scanning a QR code at a memorial stone or on a photo frame instantly opens a rich, lightning-fast media sanctuary-no app download required.

    

The Tech Stack (Flexible, but leaning toward)

• Web: Next.js (SSR is critical for SEO and instant loading).
• Backend: Node.js / Python (for AI pipelines) / PostgreSQL.
• Mobile: PWA or React Native (shared logic).

• Infrastructure: AWS S3 (secure, long-term vaulting).

   

Who you are

• You ship. You’ve launched real products to real users. You care more about "working" than "perfect."
• You own the stack. At this stage, there is no "that’s not my department." You are the department.
• You understand "The Why." If you’ve ever looked at a photo of a lost loved one and wished you could hear their story again, you are the right person.

• You are an Architect. You aren't building for the next quarter; you are building a vault meant to last for decades.

   

What we are NOT looking for

• Part-time enthusiasts or "consultants."
• Architects who want to spend 6 months drawing diagrams before shipping code.

• Anyone who needs a 50-page spec to start. We move fast and iterate.

   

The Deal

• Real Co-founder status: You have a seat at the table for strategy, fundraising, and product vision. Your name is on the company.

• Sovereign Equity: We are honest about the sacrifice of deferred salary, so we are ready to give part of ownership.

   

How to Apply
