NICE TO HAVE: * Direct experience with Claude / Anthropic models. * Experience with Supabase and Deno Edge Functions specifically. * E-commerce or marketplace platform experience (catalog, cart, checkout, payments, order lifecycle). * Construction tech, field-operations software, or other complex multi-stakeholder platform experience. ## Description Build & Own the Stack * Design, build, and ship full-stack features across frontend, backend, and data layers. * Own systems end-to-end - auth, multi-tenancy, billing, and deployment - as connected concerns, not isolated tickets. * Make pragmatic architecture decisions early, ship them, and refine as the product and requirements evolve. AI & Data * Build and maintain Python services that power data pipelines and AI workloads. * Integrate LLMs (Claude / Anthropic and others) into real product workflows - not demos. * Apply sound data modeling and query design in Postgres to keep the platform fast and reliable as it scales. Integration & Reliability * Wire up third-party and enterprise APIs, handling authentication, rate limits, and pagination. * Build systems that recover gracefully when upstream services misbehave. Team & Culture * Collaborate directly with the CTO and early team to set technical direction. * Contribute to a fast-moving, low-process culture that values ownership, directness, and judgment. ## Related Videos - [Under the Hood of Building on Lovable](https://www.wearedevelopers.com/videos/100032-under-the-hood-of-building-on-lovable) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Intro to FastAPI](https://www.wearedevelopers.com/videos/462-intro-to-fastapi) - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence)
