We’re hiring a senior, hands-on engineer to support multiple early-stage products that need stabilization.
Most projects were built quickly by non-technical founders using AI tools. As a result, codebases are often incomplete, inconsistent, or fragile.

Review and assess existing codebases (often AI-generated or founder-built)
Identify bugs, structural issues, and technical risks
Refactor and stabilize applications for production use
Improve performance, structure, and maintainability
Fill gaps in core functionality (auth, payments, backend logic)
Implement lightweight QA / testing where needed
Collaborate with engineers, QA, and project leads
Work across multiple projects as priorities shift
5+ years of full stack experience
Strong experience working in messy / inherited codebases
Comfortable operating without full documentation
Proven ability to take products from MVP → stable product
Practical, solution-oriented mindset (not theoretical)
Strong communication and team collaboration
Comfortable in fast-moving, delivery-focused environments
Python (FastAPI, Django) - preferred
Node.js / TypeScript
React / Next.js
Firebase, Supabase, or similar
APIs & modern web architectures
Flexibility > specialization
Fractional, hourly
10–40 hrs/week depending on project load
