Job description

Role Summary

We are looking for experienced full stack contractors to build production-grade web applications and APIs. You will own features end to end — from database schema through backend services to the user interface. This is a hands-on build role for engineers who are comfortable working through ambiguity, shaping the design as much as writing the code, and operating as an owner rather than a ticket-taker.

Must-Have Skills

Frontend

• React experience preferred (hooks, state management, component architecture)
• Proficient in Python, writing production-grade code
• Hands-on experience with FastAPI or Flask for building REST APIs

Database

• Experience with relational databases (PostgreSQL, MySQL, SQL Server, or equivalent)
• Good understanding of schema design, joins, indexing, and query optimization

Architecture & Problem Solving

• Ability to think through system design and build scalable solutions
• Strong analytical mindset to break down complex or ambiguous problems

Good-to-Have Skills

• Experience with Claude Code or other AI-assisted development tools — extra points for this
• desktop app based on Electron framework - Extra points for this
• Agentic Frameworks (ADK, Langraph )
• API documentation (Swagger / OpenAPI)
• Git and version control best practices
• Basic DevOps awareness (Docker, CI/CD)
• Testing experience, both unit and integration

These are weighted equally with technical skill. Candidates who are strong engineers but weak here will not be a fit.
