Marina Zorina

AI-native product builder · Founder of CrewTask

Full-remote from Mexico · GMT-5 ± 4 hLinkedInTwitter/XPortfolioGitHub

Summary

I take a vague idea to a shipped, reliable AI product and own it end to end - CrewTask, live on Google Play, built solo. I own what gets built and how we prove it works: strategy, architecture decisions, decomposition, acceptance criteria - and I run a team of AI agents the way a product owner runs a team. Fifteen years in engineering - on why systems fail and how to prove they don't - is where the reliability comes from.

Looking for: Co-founder & CEO who builds, Head of Product / AI Product Lead or Entrepreneur in Residence at an AI-first startup or venture studio, pre-seed to Series A.

Products I Built

Founder-CrewTask, AI-powered Family OSNov 2025 - present
  • Took the product from idea to a live Android app in Google Play open testing, solo and part-time: about 3 months of development plus a month of store release.
  • Voice note in, structured family tasks out: three-tier Gemini orchestration with a Groq fallback; an eval suite of 49 labeled examples in three languages, with an accuracy threshold checked before parser releases.
  • Multi-tenant Supabase with RLS, offline-first sync, 330 unit and 96 E2E tests, Sentry in production. Next: M-Tribe, a community layer of verified families nearby.

Author-Release Harness, open source (MIT)2026
  • Slash commands and checks that make an AI coding agent show its work instead of just saying "done", plus an 8-module release pipeline distilled from CrewTask's production.
  • 14 commands and 21 prompts, each scored: structure evals in CI and an LLM judge over written cases.

Core contributor-Yukti, open-source mobile UI automation (MIT)Sep 2026
  • 91 of 102 commits, all 26 pull requests and all 57 issues in two weeks: engine work on Android and iOS, assertions, conditional steps, per-step JUnit report and CI.

Also built solo through AI orchestration: Health Assistant (MVP with a live demo; on-device document recognition and a state model where every number is calculated by fixed formulas in code, and the LLM only explains the results in plain language) and a Research Agent (Python, 13 login-free sources, three-layer LLM matching, running twice a day).

Client Work

Stealth-mode HealthTech-Agentic AI · Silicon ValleyAug 2026 - present
  • Help shape how the product is released and work on the product itself: parts of the code, the testing framework, and a UI kit with a review of the product's screens.
  • Found green reports standing over runs whose checks never executed and closed the gap in CI; the daily report grew from 972 checks to 7,479. Regulated industry: synthetic personas only.
Consultant-Large fintech, a major bankApr 2022 - present
  • API-heavy product team: payments, fraud detection, account linking.

Background

Engineering-EdTech (100K MAU) and media2013 - 2022
  • Built the release function at an EdTech from scratch: hired and led a team of 3; release cycles went from 1-2 weeks to 1-2 days.
  • What I built kept working after I left: the two people I grew both moved on at about twice their salary, and the automated reports kept running for years.
Business Analyst-NIKA Watch FactoryDec 2010 - Jul 2013
  • Business analysis and budget management for manufacturing operations.
Lead Consultant / BI Developer-ENPI ConsultJan 2006 - Nov 2009
  • OLAP management reporting from invoice to C-level KPIs; multi-year financial modeling for the unbundling of RAO UES, the restructuring of Russia's national electricity grid.
