We're a productized AI service running an agent runtime — one isolated instance per customer — on a stack of FastAPI, Next.js 14, Postgres, and Docker. We're past MVP and into production hardening: real customers, real revenue, real SLAs. Inherit and improve the existing FastAPI control plane (routes, async SQLAlchemy 2.0 + asyncpg, Pydantic, JWT, Stripe billing, APScheduler) Tighten the Next.js 14 / React 18 / Tailwind / Clerk auth frontend Improve security posture: per-tenant row-level security in Postgres, input validation, rate limiting Performance pass: SSE streaming, DB query optimization, caching layer Work alongside an AI agent engineer and a Twilio specialist (separate hires) Required: 7+ years full-stack production experience Deep FastAPI + async Python (NOT a Flask/Django person retrofitting) Next.js 14 App Router + TypeScript at production scale Postgres at scale — async drivers, RLS, query planning Docker, comfortable with Render or similar managed infra Comfortable inheriting a working codebase — you read before you rewrite Nice to have: Multi-tenant SaaS architecture experience Stripe metered billing Clerk or similar managed auth Sentry, observability Have inherited and improved an AI/LLM-adjacent platform before How we work: This is an ongoing engagement, not a one-off. 20–30 hrs/week. Async-friendly but US time zones strongly preferred for sync calls. We pay $80–150/hr depending on seniority. We are not the lowest bidder's client. Paid 4–8 hour trial task (real codebase work) before any retainer.

I have built out an MVP using lovable for the wedding content creator community. It is a gallery platform where they upload their iphone videos and it displays in a gallery (Like pic-time, pixieset, etc). Our users primarily record 4k short form iphone videos and the upload pipeline is the most important piece. I dont have background in any of this and have only build with lovable, but the business is growing quickly and I would love some help to fix bugs and harden the pipelines/overall architecture. We use Cloudflare, Backblaze, Mux, Fly, and Lovable. We haave also built out an app that is on Testflight (Primarily what our users are using to upload).

We are seeking a Mid to Senior-level Fullstack Developer (3–5 years of experience) to not only maintain and expand our platform (Next.js frontend + Django backend) but also guide us in fully integrating AI-powered coding assistance across the full stack. The frontend is already set up for AI-assisted editing (e.g. Cursor), and we want to evolve our backend similarly. The ideal candidate will help us transition the entire development environment, so both we and the developer can leverage state-of-the-art AI coding tools. Beyond coding, you’ll act as a mentor, helping us better understand the backend’s architecture and workflows while integrating AI-driven development tools into our process. You’ll have a key role in making our stack both stable and future-ready, with AI-assisted flexibility. The Context Our frontend was recently ported to Next.js in an ad-hoc manner, leaving certain sections in need of refactoring and stabilization. We have committed to keeping our backend in Django to leverage its robust processing capabilities. You will be the point person for bridging these two environments. Key Responsibilities -Maintenance & Stability: Perform routine maintenance and optimization across the full stack. -Bug Fixing: Identify and resolve issues within the existing Next.js frontend and Django backend. -System Reliability: Provide technical support and troubleshooting during system downtime. -Feature Implementation: Build and deploy new features, ensuring seamless integration between the AI pipeline and the user interface. Required Technical Profile -3–5 years of professional fullstack experience. -Frontend: Proficiency in Next.js and React; experience cleaning up/refactoring "messy" or legacy codebases is a plus. -Backend: Strong experience with Django (Python), specifically working with complex data pipelines or API integrations. -Mindset: A pragmatic approach to coding—balancing the need for new features with the necessity of technical debt reduction.
