Most side projects die in the idea phase. Not because the ideas are bad, but because there is no constraint forcing them to ship. At work, you have deadlines, stakeholders, and a definition of done. Side projects have none of that. So they sprawl, stall, and quietly rot in a git repo.
I built PiggyPing - an AI-powered expense tracker - by applying the same discipline I use at work. Fixed scope. Defined MVP. Weekly milestones. A ship date that I told people about so I could not quietly abandon it.
The first step was scope cutting. My initial feature list had 30 items. I crossed out 22 of them. The MVP was: snap a receipt, extract the data with AI, categorize it, and show a monthly summary. That is it. No budgets. No shared expenses. No export. Those are version two features. Version one needs to do one thing well enough that someone would use it twice.
The second step was time-boxing. I gave myself weekends only. Friday evening to Sunday evening. No weeknight coding because that leads to 1am sessions and burned-out Monday mornings. Each weekend had a specific goal: weekend one was the receipt scanning flow. Weekend two was the AI extraction pipeline. Weekend three was the dashboard and category views. Weekend four was polish and launch.
The third step was treating launch as a forcing function. I bought the domain early. I set up the landing page before the app was built. I told five friends to try it on a specific date. These small commitments created real pressure. Not stressful pressure, but the productive kind that turns maybe-I-will-finish into I-need-to-finish.
The technical stack was intentionally boring. Next.js, TypeScript, Tailwind, Vercel. Tools I know cold. The goal of a side project is to explore one new thing, not five. For PiggyPing, the new thing was the AI receipt parsing pipeline. Everything else was deliberately familiar so I could move fast without debugging infrastructure.
PiggyPing shipped. It is not perfect. The AI misreads handwritten receipts. The category suggestions are wrong 15% of the time. But it exists. People use it. And every improvement from here is iteration on a live product, not speculation on a hypothetical one.
The lesson is simple: treat side projects like products. Define the MVP. Set a deadline. Cut everything that is not essential. Use boring tools. Ship it. Then improve it. The gap between a shipped imperfect product and an unshipped perfect idea is infinite.
