CollegeVine is an online platform that offers college admissions guidance and mentorship to high school students, aiming to help students navigate the often complex and stressful college admissions process with confidence and support. The platform offers a range of services, including college essay review, application strategy development, a college admissions blog, a school research tool, and a free admissions calculator. But the real value is the networking aspect: with a professional CollegeVine profile highlighting their achievements, many students engage directly with admissions officers and eventually receive generous financial aid and direct admissions offers right on our website.Technically, CollegeVine is a pretty traditional web app (not an SPA), backed by a relational database. It’s using Rails as backend, a couple supporting services written in Haskell, and the browser front-end is mostly (but not 100%) written in PureScript. We have a non-trivial data science department, which powers many of our user-facing features, but I don’t think I’m qualified to talk about it, and not sure what I can say and what I can’t.My official title in the company is “Principal Software Engineer”, and it reflects what I do pretty well. Like everybody else, I write code, work with product owners and designers, but on top of that I do things like mentorship, supporting lower-level libraries and tools, weighing in on design decisions, technology choices, promoting practices, and so on.
