Like most cases, the answer is always “it depends”. Without knowing too much about the application and the state of the startup (do you have users? do you have funding-related milestones or are you bootstrapping?), it’s tricky to recommend a production stack off the bat. Most basic versions of production web apps could be backends coupled with an ORM like Ruby on Rails/Django/Spring/etc. No need to complicate things by splitting the front-end since you’re the only developer and your experience is ERP. Pick a tech that you’re strong with and reuse popular battle-proof libraries. Deploy to application platforms and offload the infrastructure management if your startup can afford it. You can also leverage fractional CTO services to help guide you through the process. Personally, I’ve mentored a few junior developers on an ad-hoc, hourly basis to help them build out their expertise.
