We build AI-powered consumer apps. Our first product, Goodie AI, is a food analysis app live on both app stores, has reached 100K downloads in 6 months with 4.9 rating, and 100M+ views on TikTok, and is now heading towards an acquisition. 

Now we're scaling that playbook into a portfolio of new apps across different verticals. Same approach across multiple bets: AI-native and mobile-first.
 

  The Role
 

  You'll be our first engineering hire and a co-builder across everything we launch. This isn't a single-product job. You'll help us ideate,

  prototype, and ship multiple new apps, picking the right stack for each, building the first version, and getting it into users' hands. Some

  will be quick experiments. Some will become real businesses. You'll be in the room for all of it.

  What You'll Do

  - Go from idea to shipped product 

  - Make foundational architecture and technology decisions for new apps

  - Build full-stack: mobile frontends, serverless backends, AI integrations

  - Own the entire lifecycle: prototype, launch, iterate, scale

  - Work directly with the founders to shape product direction

  What You Bring

  Must-have:

  - Strong TypeScript across the stack

  - Deep experience with React Native + Expo or willingness to work in mobile

  - Proficiency with serverless backends (Supabase, Firebase, or similar)

  - Hands-on experience with LLM/AI APIs — prompt engineering, structured outputs, building AI-powered features

  - You've shipped products to real users — side projects, startups, whatever. You know what it takes end-to-end.

  - Thrives in ambiguity. You don't need a spec — you need a problem.

  Strong plus:

  - Experience with mobile monetization (subscriptions, paywalls, RevenueCat, Stripe)

  - Familiarity with mobile growth & analytics (attribution, A/B testing, product analytics)

  - App Store and Google Play submission and release management

  - Background building multi-language / international products

  Nice-to-have:

  - Experience in health, nutrition, fitness, or consumer AI

  - Eye for design and UX. You can build something that looks good without a designer in the room

  - Prior founding or early-stage startup experience

  What We Offer

  - Founding-level equity

  - Real influence over what gets built and how

  - A team that's already proven it can ship 

  - The chance to build multiple products, not maintain one

Hi. I'm hiring one developer to help me ship features and fix bugs on Dr.Fit, a fitness and nutrition app with thousands of active users. React Native + Go + Postgres.

I'm not a developer myself. I've been shipping production code for months using Claude Code and Cursor. It works. I want to hire someone who can do this faster and better than me, for one focused part-time role.

THE ROLE
- $600/month, flat. Paid via Wise.
- 4 hours/day, Monday to Friday. You pick your hours.
- Remote. Anywhere in Ukraine.
- Two-week paid trial first ($250). If we both want to continue, we commit.

WHAT YOU'LL DO
- Fix bugs in the React Native app
- Build small and medium features across frontend, Go backend, and support tooling
- Open PRs. I review and merge to production.
- Daily async written standup plus 1 to 2 short calls per week.

If this works out, more hours and more pay are on the table. We figure that out based on what you ship, not a calendar.

WHO I'M LOOKING FOR
- You use Claude Code, Cursor, or similar AI tools every day. Heavily.
- You ship things. You finish them. You don't disappear mid-task.
- English: confident written and spoken. We'll talk on calls.
- You read unfamiliar code and figure things out without hand-holding.
- You care about whether the user's app works, not whether the architecture is pretty.
- You tell me when something is broken or worth building. I don't want to manage you.

WHAT I DON'T CARE ABOUT
- CS degree
- 5 years of experience
- Whether you already know Go or React Native (you'll learn fast with AI)
- LeetCode

HOW TO APPLY
There's a test task on GitHub. It's small (10 to 60 minutes), public, and replaces the CV:

https://github.com/YordanBahov-bg/dr-fit-hiring-test

Fork it. Investigate. Fix what's broken. Add the small feature. Record your full session (Loom's 5-minute free cap won't fit, figure out what works for you, that's part of the test). Open a PR back to the repo.

I respond to every submission within 48 hours.

That's it. No CV needed.

• Strong hands-on experience with ASP.NET Core, EF Core, PostgreSQL or MSSQL
• Solid understanding of async, concurrency, and distributed systems
• Experience with microservices and message-driven architectures
• English B1+ (working language is English in writing; team speaks Russian)
• iGaming / RGS / regulated-industry experience — strong plus, not a requirement

What we offer

• Full-time, fully remote, comfortable with Ukrainian time zones
• Long-term role with real ownership — not a short project
• Direct line to CTO, no bureaucracy
• Competitive USD-denominated rate
• Paid vacation, sick days
   

Our hiring process (no test tasks — we respect your time)

1. 30-min intro call — culture, expectations, light tech check
2. 60-min technical interview with our CTO — past-project deep-dive + system design or live coding
3. 2 reference calls — with people who managed or worked closely with you
4. Offer

Looking forward to talking.
