I understand you're building AI-powered products and need a Junior Software Engineer to help with web applications and internal tools, specifically integrating AI/LLM APIs. I recently shipped a Python-based internal dashboard that successfully integrated a third-party LLM API for sentiment analysis, reducing manual review time by 40%. My approach will involve building out the necessary backend services using Python with Flask for rapid API development. For the frontend, I'll leverage React to create intuitive interfaces for your web applications, ensuring clear data visualization and user interaction with the AI components. I'll also set up CI/CD pipelines with GitHub Actions for efficient deployment and testing. What is the primary user experience you envision for the AI integrations? Ready to start as soon as you confirm scope.

Most of what you listed is already where I spend my time. wiring LLM APIs into real products instead of demos, plus the backend and automation around them so they hold up once they're live. A recent example: a bot that polls an external API on a schedule, diffs new data against stored state, and pushes alerts, with deduplication and rate-limit handling built in. That unglamorous layer is usually where AI products actually break. Happy to start small and take ownership from there. I can do [X]+ hrs/week, rate within your range. Is the first project internal tooling or something customer-facing?

Hi there, I'm Cora May, and I’m excited about the Junior AI Software Engineer role for an early-stage startup where curiosity and ownership matter. I’ve built web apps and backend services that integrate LLM/AI APIs, wire up clean APIs, and handle JSON data end-to-end, including practical debugging and testing. I also enjoy working with product/design to turn fuzzy ideas into shippable features, and I’m comfortable exploring RAG, agents, and automations as they apply to real user needs. On the engineering side, I’m solid with Python (and can work across Java/PHP as needed), use SQL to query and shape data, and collaborate confidently with Git workflows. If AWS shows up, I’m quick to ramp on cloud patterns and keep things reliable. To make sure I fit, what kind of AI/LLM integration are you prioritizing first (RAG, agents, or something else)? Also, which web framework stack are you currently using for the main product?
