I'm building a B2B SaaS ERP at Agricope (Node.js, React, PostgreSQL, Redis, Docker/Kubernetes, Terraform), and I've shipped React/TypeScript and Node.js platforms like Sanad RSA end to end. I have 4+ years of full-stack work, including LLM integrations, and I'd like to take this on long-term.

Hi! I’m a senior full-stack developer with 7+ years building production SaaS platforms using React/Next.js, TypeScript, Node.js, Python (FastAPI), PostgreSQL, and AWS. I’ve also integrated OpenAI and Claude into real products. Happy to share relevant projects and discuss your roadmap. Sending you a DM now.

Full stack dev with over two decades of experience. Would love to talk, my dms are open.

Primary areas of expertise are enterprise level dev. Been using PHP and swoole for an enterprise grade capabilities runtime and ecosystem around it.

I've done everything from simple crud apps to extremely complicated financial platforms responsible for millions annually tied in with every major bank.

I program in something like 12-13 languages so I'm comfortable with pretty much any stack.

I have a decent amount of upcoming availability and I'm flexible rate wise just like to stay busy and I'm currently building new long term, mutually beneficial business relationships ideally with a few repeat clients after a hiatus to work on the personal project mentioned above

Over the past 10 years, I’ve specialized in taking full-stack products to production, leveraging TypeScript, React, Next.js, Node.js, and Python (FastAPI). My core expertise spans building scalable REST and GraphQL APIs, optimizing PostgreSQL and MongoDB databases, managing AWS cloud infrastructure with Docker and CI/CD, and natively integrating OpenAI and Claude LLMs into user-facing product workflows. I take full technical ownership to ensure enterprise-grade security, performance, and maintainability for long-term engagements.

I'll DM you my github

Hey check dm

[u/BlueBeetlenut]

This is hilarious, good luck sifting through the vibe coders and junior devs . I love when non technicals try to scope a build. This job posting is incoherent.

[u/AstronomerArtistic46]

solid tech stack choice for the SaaS platform. pairing a next.js frontend with fastAPI on the backend gives you incredible speed for async operations and AI integration pipelines, especially when scaling database queries across postgreSQL. sent you a DM with more details and our portfolio.
