Project details

I build AI automation and integrations for ERP and business systems, and ship them as working, deployed software, not a mockup.

Most ERP automation stalls for one reason: the fear of letting software touch live financial data. I solve that directly. My AI agents write to a staging table first, a person approves, then the change commits in one transaction that can be rolled back. Every failed record is kept with its payload and reason, deduplicated and exportable, so nothing is silently lost.

What I automate and connect: purchase and month-end closing (aggregate, email suppliers, verify replies, post tax invoices, report), reconciliation, loss-less sync between two ERPs or an ERP and a commerce system, and inventory-to-settlement flows.

Stack: Python/FastAPI, MSSQL and common ERP databases, Ecount-type accounting, Supabase/Postgres, OpenAI and Claude.

Working demos are in the gallery. I work end to end: shape, build, deploy, and maintain, in plain language. Senior engineer, 3+ years shipping production AI systems. Tell me what you want to automate and I will say honestly whether it fits.

About JoonBae

JoonBae J.Status: Offline
Senior Full-Stack Engineer | Web Apps, SaaS & Automation + AI
Seoul, South Korea - 9:16 am local time
Hi, I'm a senior engineer. I spent many years building software in Korea, and I recently came to Upwork to work with more great clients around the world.

I can partner with you across the whole journey, from the first planning stage to launch. Years of building products, and of working closely with clients, taught me that the best results don't start with technical jargon. They start with listening. I take time to understand what you really want, agree on a clear scope and milestones with you, and stay with it to the finish.

I've worked across a wide range of domains: full-stack web apps and SaaS, GIS and mapping platforms, real-time data and trading dashboards, legal and document AI, IoT and data pipelines, and business automation. My core stack is Python, Node, and React/Next.js with Supabase/Postgres, and I add AI (RAG, chatbots, LLM and agent integrations) wherever it genuinely makes the product better.

What clients value most: I take your brief and turn it straight into a working PoC, so you can use and test it before you decide. I also bring ideas of my own into it, so you end up with something you can grow a real business on, not just what was asked for.

Because I work fast, I usually prefer fixed-price projects, though I'm always happy to stay flexible when it makes sense.

I'd love to meet you and get started. Thank you for reading.
