Maria Chen has been teaching AP Chemistry and Physics at Lincoln High School for eleven years. Like every teacher, she spent countless hours on the administrative side of teaching — creating assignments, distributing them, collecting submissions, grading, recording scores, and sending feedback. She'd tried every tool on the market.
The Problem
"Google Classroom is fine for basic assignments, but it doesn't understand the workflow of a science class," Maria explains. "I need to attach lab protocols, accept photo submissions of lab notebooks, grade with rubrics that change per assignment, and track which students need to redo experiments. No tool did all of that."
She was managing a patchwork of Google Classroom, Google Sheets, email, and a physical gradebook. Students would submit work to the wrong place. Parents would email asking for updates she'd already posted. Grades lived in three different systems.
Building ClassFlow
Maria had heard about AI-powered development from a colleague who'd built a personal budgeting app over a weekend. She decided to try describing her ideal homework platform to Velosyti.
"I described exactly what I needed: a place where I can create assignments with custom rubrics, where students submit work including photos and files, where I can grade with the rubric and leave inline comments, and where parents can see their kid's progress in real-time."
The first version was ready in under an hour. Maria spent a weekend refining it — adding a lab notebook submission flow, a rubric builder, and an automatic "missing assignment" notification system.
The Results
ClassFlow launched at the start of the spring semester. Within a month, all four of Maria's classes were using it daily.
"The first week, a parent emailed me to say it was the first time she could actually see what her daughter was working on without having to ask. That's when I knew it was working."
Maria estimates she saves about 12 hours per week — time she previously spent on data entry, chasing submissions, and answering status questions that parents can now look up themselves.
What's Next
Word spread to other teachers at Lincoln High. Three of Maria's colleagues now use ClassFlow for their own classes. She's considering opening it up as a paid tool for other schools.
"I never thought of myself as someone who could build software. I'm a chemistry teacher. But the tool I needed didn't exist, so I built it. That still feels surreal to say."
