Sr. Full-stack Developer - FT Freelance - Worldwide

Hi, we’re Overgo! We help people select and book the right hotel using natural language and AI. Built for discerning travelers who value both high-tech and high-touch service, Overgo makes discovering a hotel feel as effortless as having a conversation. We’re backed by the leadership of Booking.com and other industry innovators, giving us both credibility and momentum as we scale. Our mission is to blend the best of technology and hospitality — using AI not to replace the human touch, but to elevate it. If you thrive on autonomy, creativity, and the chance to shape an early-stage product that’s redefining luxury travel, we’d love for you to join our team.**

Role Overview
**We’re looking for a scrappy, fast-moving developer who can help us bring Overgo’s MVP live by October 1st. In this role, you’ll use Streamlit to spin up working prototypes of our hotel discovery and booking experience in days, not weeks. The focus is on speed, iteration, and testing big hypotheses — creating interactive demos that show the “magic” of Overgo before we invest in a polished production build. You’ll work closely with leadership and a product designer to ensure the prototypes align with the front-end vision.

Responsibilities

• Build the front-end UX layer of Overgo’s discovery and booking flows in Streamlit, ensuring it is intuitive and user-friendly for the go-to-market MVP (October 1).
• Connect backend booking and payment engine (Nuitee LiteAPI) and display results interactively.
• Plug in natural language search powered by LLMs (OpenAI API).
• Develop working versions of hotel comparison UI, booking flows, save-hotel functionality, and email-based trip retrieval
• Work closely with leadership and a product designer to translate design into a usable MVP experience.
• Iterate quickly based on feedback from leadership, advisors, and early testers.

Qualifications

• Strong experience with Streamlit and rapid prototyping.
• Proficiency with Python for backend logic and API integration.
• Familiarity with LLM integration (prompt engineering, embeddings, OpenAI API).
• Ability to work independently and ship fast.
• Bonus: Experience with travel APIs (Nuitee LiteAPI or other booking engines).
