I’m looking for a senior builder who can move fast.

You’ll work directly with me to turn raw ideas into working prototypes and MVPs.
No corporate red tape. No long planning cycles.

We’ll:
- Talk through ideas
- You build a fast prototype
- We test it
- If it works → I move it to a full dev team
- You move on to the next idea

This role is about speed, creativity, and execution.

What You’ll Do
- Rapidly build MVPs and prototypes from scratch
- Turn rough ideas into real, working products
- Own frontend, backend, and infrastructure:
- Use AI tools to code faster (“vibe coding” encouraged)
- Spin up projects quickly (auth, APIs, databases, deployments)
- Iterate based on feedback in real time
- Document handoff for full dev team when MVP is validated

Tech & Tools You Should Be Comfortable With

Core
- JavaScript / TypeScript
- React / Next.js
- Node.js / Python
- REST & GraphQL APIs
- SQL + NoSQL databases

Infrastructure
- AWS / GCP / Vercel / Railway
- Docker (nice to have)
- CI/CD
- Auth systems
- Stripe / payments (bonus)

AI Stack




- OpenAI / Anthropic APIs
- LangChain / LLM tooling
- Prompt engineering
- RAG systems
- Vector databases (Pinecone, Weaviate, etc.)

Workflow
- GitHub
- Rapid prototyping
- No-code + low-code when useful
- AI coding assistants (Cursor, Copilot, etc.)

Who You Are
- Senior dev (5+ years experience)
- Product-minded (not just code)
- Can build end-to-end alone:
- Comfortable with ambiguity
- Enjoys fast iteration
- Strong communicator (we’ll work closely)
- You think in MVPs, not perfection
- You _ship_

Bonus Points
- Startup experience
- Built SaaS products before
- Experience scaling MVPs
- Design sense (UI/UX basics)
- Automation background

How We’ll Work
- Daily async communication
- Weekly live brainstorming calls
- You build → I test → we iterate
- You’re not stuck maintaining old code forever
- Once validated → handoff to full team → next build

Pay: From $70,000.00 per month
