• Fullstack Development : Build and maintain features across the stack: React/Next.js frontend, Node.js/NestJS backend, PostgreSQL. • Develop clean, well-documented APIs with strong error handling. • Implement pixel-perfect, responsive UI when working on the frontend. • Contribute to architectural decisions — data modeling, service boundaries, performance. • Code Quality & Engineering : Refactor and improve existing code — better structure, clearer naming, stronger typing, fewer surprises. • Write and maintain tests. Increase coverage where it matters most. • Improve typing where it’s weak — meaningful types, not `any` everywhere. • Identify and reduce technical debt. Leave every file better than you found it. Review code with care. Catch the things others miss. • AI & Automation (Optional) : Work on AI-powered features: LLM integrations, agent workflows, prompt engineering. Contribute to our agents layer in Python if comfortable (LangChain). • Collaboration : Work with the engineering team daily. Communicate proactively about progress, blockers, and decisions. • Be self-directed. You’ll have high autonomy — use it well. Participate in planning and prioritization. Flag risks and blockers early.
